java 打包发布到docker java项目如何打包发布

零、跳过单元测试

<!-- 跳过单元测试 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3.2</version>
                <configuration>
                    <skip>true</skip>
                    <!--<source>${java.version}</source>
                    <target>${java.version}</target>-->
                    <encoding>${project.build.sourceEncoding}</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>

一、打包

1、在pom.xml中指定main类

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
       <appendAssemblyId>false</appendAssemblyId>
       <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
       </descriptorRefs>
       <archive>
          <manifest>
             <!-- 此处指定main方法入口的class -->
             <mainClass>com.a.App</mainClass>
          </manifest>
       </archive>
    </configuration>
    <executions>
       <execution>
          <id>make-assembly</id>
          <phase>package</phase>
          <goals>
             <goal>assembly</goal>
          </goals>
       </execution>
    </executions>
 </plugin>

 

普通项目达成一个jar

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>single</goal>
                        </goals>
                        <phase>package</phase>
                        <configuration>
                            <descriptorRefs>
                                <descriptorRef>jar-with-dependencies</descriptorRef>
                            </descriptorRefs>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

2、打第三方包的mvn命令

#dependency:copy-dependencies 是将依赖的包打到dependency目录下
打包：clean package dependency:copy-dependencies 

#-DoutputDirectory=lib 是将依赖的包打到指定（lib）目录下
打包：clean package dependency:copy-dependencies -DoutputDirectory=lib

 

二、项目启动

例：

jar包path: D:\software\eclispe-workspace\eclipse13\sunxj-package\target\lib\sunxj-package-0.0.1-SNAPSHOT.jar

D:\software\eclispe-workspace\eclipse13\sunxj-package\target>java -jar lib/sunxj-package-0.0.1-SNAPSHOT.jar com.a
+++++++++++++package-test++++++++++++++++

D:\software\eclispe-workspace\eclipse13\sunxj-package\target>java -classpath lib/* com.a.App
+++++++++++++package-test++++++++++++++++

D:\software\eclispe-workspace\eclipse13\sunxj-package\target>java -cp lib/* com.a.App
+++++++++++++package-test++++++++++++++++  注：类加载器为app

D:\software\eclispe-workspace\eclipse13\sunxj-package\target>java -Djava.ext.dirs=lib com.a.App
+++++++++++++package-test++++++++++++++++  注：类加载器为ext

 

三、第三方包打到lib下

1、pom配置：

<build>
         <!-- 用指定的jdk版本打jar包 -->
         <plugins>
             <!-- <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-compiler-plugin</artifactId>
                 <configuration>
                     <source>1.7</source>
                     <target>1.7</target>
                     <encoding>UTF-8</encoding>
                 </configuration>
             </plugin> -->            <!-- 将依赖的jar包打到lib目录下 -->
             <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-jar-plugin</artifactId>
                 <configuration>
                     <archive>
                         <manifest>
                             <addClasspath>true</addClasspath>
                             <!-- 指定出程序的入口类 -->
                             <classpathPrefix>lib/</classpathPrefix>
                             <!-- 依赖JAR包输出到了lib -->
                             <mainClass>com.test.service.ServerStartup</mainClass>
                         </manifest>
                     </archive>
                 </configuration>
             </plugin>
             
             <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-dependency-plugin</artifactId>
                 <executions>
                     <execution>
                         <id>copy</id>
                         <phase>package</phase>
                         <goals>
                             <goal>copy-dependencies</goal>
                         </goals>
                         <configuration>
                             <outputDirectory>${project.build.directory}/lib</outputDirectory>
                         </configuration>
                     </execution>
                 </executions>
             </plugin>        </plugins>
     </build>

2、目录结构

3、启动脚本

java -jar sunxj-mail-0.0.1-SNAPSHOT.jar

 

四、SpringBoot--使用appassembler-maven-plugin打包

      appassembler-maven-plugin是一个用来为Java应用打包并生成启动脚本的Maven插件，使用起来非常简单，只需要在项目的pom.xml中加入插件的相关配置即可。它在脚本打包过程中，能够将项目的所有依赖自动复制到指定的打包目录中，并将这些依赖添加到classpath中。

官网地址：http://www.mojohaus.org/appassembler/appassembler-maven-plugin/  

一：生成可执行的启动脚本

打包命令：mvn clean package appassembler:assemble 

<build>
         <plugins>
             <plugin>
                 <groupId>org.codehaus.mojo</groupId>
                 <artifactId>appassembler-maven-plugin</artifactId>
                 <version>2.0.0</version>
                 <configuration>
                     <!-- 生成linux, windows两种平台的执行脚本 -->
                     <platforms>
                         <platform>unix</platform>
                         <platform>windows</platform>
                     </platforms>
                     <!-- 包存放的根目录 -->
                     <assembleDirectory>${project.build.directory}/${project.name}</assembleDirectory>
                     <!-- 打包的jar，以及maven依赖的jar存放目录 -->
                     <repositoryName>lib</repositoryName>
                     <!-- lib目录中jar的存放规则，默认是${groupId}/${artifactId}的目录格式，flat表示直接把jar放到lib目录 -->
                     <!-- 可执行脚本的存放目录 -->
                     <binFolder>bin</binFolder>
                     <!-- 配置文件的存放目录 -->
                     <configurationDirectory>conf</configurationDirectory>
                     <!-- 拷贝配置文件到上面的目录中 -->
                     <copyConfigurationDirectory>true</copyConfigurationDirectory>
                     <!-- 从哪里拷贝配置文件 (默认src/main/config) -->
                     <configurationSourceDirectory>src/main/resources</configurationSourceDirectory>
                     <repositoryLayout>flat</repositoryLayout>
                     <encoding>UTF-8</encoding>
                     <logsDirectory>logs</logsDirectory>
                     <tempDirectory>tmp</tempDirectory>
                     <programs>
                         <program>
                             <!-- 启动类 -->
                             <mainClass>com.pengjunlee.MyApplication</mainClass>
                             <jvmSettings>
                                 <extraArguments>
                                     <extraArgument>-server</extraArgument>
                                     <extraArgument>-Xmx1G</extraArgument>
                                     <extraArgument>-Xms1G</extraArgument>
                                 </extraArguments>
                             </jvmSettings>
                         </program>
                     </programs>
                 </configuration>
             </plugin>
         </plugins>
     </build>

二：生成后台服务程序

打包命令：mvn clean package appassembler:generate-daemons

Usage: { console | start | stop | restart | status | dump } 
    <build>
         <plugins>
             <plugin>
                 <groupId>org.codehaus.mojo</groupId>
                 <artifactId>appassembler-maven-plugin</artifactId>
                 <version>2.0.0</version>
                 <configuration>
                     <!-- 根目录 -->
                     <assembleDirectory>${project.build.directory}/${project.name}</assembleDirectory>
                     <!-- 打包的jar，以及maven依赖的jar存放目录 -->
                     <repositoryName>lib</repositoryName>
                     <!-- 可执行脚本的存放目录 -->
                     <binFolder>bin</binFolder>
                     <!-- 配置文件的存放目录 -->
                     <configurationDirectory>conf</configurationDirectory>
                     <!-- 拷贝配置文件到上面的目录中 -->
                     <copyConfigurationDirectory>true</copyConfigurationDirectory>
                     <!-- 从哪里拷贝配置文件 (默认src/main/config) -->
                     <configurationSourceDirectory>src/main/resources</configurationSourceDirectory>
                     <!-- lib目录中jar的存放规则，默认是${groupId}/${artifactId}的目录格式，flat表示直接把jar放到lib目录 -->
                     <repositoryLayout>flat</repositoryLayout>
                     <encoding>UTF-8</encoding>
                     <logsDirectory>logs</logsDirectory>
                     <tempDirectory>tmp</tempDirectory>
                     <daemons>
                         <daemon>
                             <mainClass>com.pengjunlee.MyApplication</mainClass>
                             <platforms>
                                 <platform>jsw</platform>
                             </platforms>
                             <generatorConfigurations>
                                 <generatorConfiguration>
                                     <generator>jsw</generator>
                                     <includes>
                                         <include>linux-x86-32</include>
                                         <include>linux-x86-64</include>
                                         <include>windows-x86-32</include>
                                         <include>windows-x86-64</include>
                                     </includes>
                                     <configuration>
                                         <property>
                                             <name>configuration.directory.in.classpath.first</name>
                                             <value>conf</value>
                                         </property>

                                         <property>
                                             <name>set.default.REPO_DIR</name>
                                             <value>lib</value>
                                         </property>
                                         <property>
                                             <name>wrapper.logfile</name>
                                             <value>logs/wrapper.log</value>
                                         </property>
                                     </configuration>
                                 </generatorConfiguration>
                             </generatorConfigurations>
                             <jvmSettings>
                                 <!-- jvm参数 -->
                                 <systemProperties>
                                     <systemProperty>com.sun.management.jmxremote</systemProperty>
                                     <systemProperty>com.sun.management.jmxremote.port=1984</systemProperty>
                                     <systemProperty>com.sun.management.jmxremote.authenticate=false</systemProperty>
                                     <systemProperty>com.sun.management.jmxremote.ssl=false</systemProperty>
                                 </systemProperties>
                             </jvmSettings>
                         </daemon>
                     </daemons>
                 </configuration>
             </plugin>
         </plugins>
     </build>

 

五、SpringBoot--使用appassembler-maven-plugin打包

1、pom.xml

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>a.App</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
<!-- maven-assembly-plugin -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>a.App</mainClass> <!-- 你的主类名 -->
                        </manifest>
                    </archive>
                    <finalName>sunxj-package</finalName>
                    <descriptors>
                        <descriptor>src/main/assembly/assembly.xml</descriptor>
                    </descriptors>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

注：spring-boot-maven-plugin可有可无。有时，启动脚本为java -jar sunxj-package.jar。没有时，启动脚本为java -cp ./lib/* a.App

2、assembly.xml

<?xml version='1.0' encoding='UTF-8'?>
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
    <id>${project.version}</id>
    <formats>
        <format>dir</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
            <directory>src/main/bin</directory>
            <outputDirectory>bin</outputDirectory>
        </fileSet>
    </fileSets>
    <dependencySets>
        <dependencySet>
            <unpack>false</unpack>
            <useProjectArtifact>true</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <scope>provided</scope>
        </dependencySet>
        <dependencySet>
            <unpack>false</unpack>
            <useProjectArtifact>true</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <scope>system</scope>
        </dependencySet>
        <dependencySet>
            <unpack>false</unpack>
            <useProjectArtifact>true</useProjectArtifact>
            <outputDirectory>lib</outputDirectory>
            <scope>runtime</scope>
        </dependencySet>
    </dependencySets>
</assembly>

 

六、springboot项目打成一个jar包

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <mainClass>com.App</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
</plugin>

启动：java  -jar sunxj-deploy.jar

jvm启动脚本可以用“-cp”指定多个文件夹、文件、jar包，用“：”分割：

/export/servers/jdk1.8.0_20/jre/bin/java -Xms5120m -Xmx5120m -XX:MetaspaceSize=128M -XX:MaxDirectMemorySize=96m -Dio.netty.allocator.type=pooled -Dio.netty.allocator.tinyCacheSize=0 -Dio.netty.allocator.smallCacheSize=0 -Dio.netty.allocator.normalCacheSize=0 -Dagent.uuid=5ad1973f51f64e8c9498cc3410e4e334 -Dtest.id=282405 -Dtestcase.id=390637 -cp /export/forcebot_bigfile/390637:/export/forcebot_cfs_local/390637/attachment:/export/forcebot_cfs_local/390637/attachment/1.txt:/export/forcebot_cfs_local/390637/attachment/pin-coupon.txt:/export/forcebot_cfs_local/390637/attachment/sunxj-genfile-1.0-SNAPSHOT.jar:/export/App/conf/:/export/App/lib/aws-java-sdk-core-1.11.600.jar:/export/App/lib/aws-java-sdk-kms-1.11.600.jar:/export/App/lib/aws-java-sdk-s3-1.11.600.jar:/export/App/lib/commons-beanutils-1.9.3.jar:/export/App/lib/commons-codec-1.11.jar:/export/App/lib/commons-collections-3.2.2.jar:/export/App/lib/commons-compiler-3.0.7.jar:/export/App/lib/commons-lang3-3.10.jar:/export/App/lib/commons-logging-1.2.jar:/export/App/lib/fastjson-1.2.72.jar:/export/App/lib/forcebot-agent-worker-3.0.0-SNAPSHOT.jar:/export/App/lib/forcebot-engine-3.0.0-SNAPSHOT.jar:/export/App/lib/forcebot-netty-3.0.0-SNAPSHOT.jar:/export/App/lib/forcebot-toolkit-3.0.0-SNAPSHOT.jar:/export/App/lib/groovy-all-2.4.11.jar:/export/App/lib/hamcrest-core-1.3.jar:/export/App/lib/httpclient-4.5.12.jar:/export/App/lib/httpcore-4.4.13.jar:/export/App/lib/ion-java-1.0.2.jar:/export/App/lib/jackson-annotations-2.8.0.jar:/export/App/lib/jackson-core-2.8.9.jar:/export/App/lib/jackson-core-asl-1.9.2.jar:/export/App/lib/jackson-databind-2.8.9.jar:/export/App/lib/jackson-dataformat-cbor-2.6.2.jar:/export/App/lib/jackson-mapper-asl-1.9.2.jar:/export/App/lib/janino-3.0.7.jar:/export/App/lib/javassist-3.18.1-GA.jar:/export/App/lib/jcommander-1.72.jar:/export/App/lib/jmespath-java-1.11.600.jar:/export/App/lib/joda-time-2.8.2.jar:/export/App/lib/json-simple-1.1.1.jar:/export/App/lib/junit-4.12.jar:/export/App/lib/logback-classic-1.2.3.jar:/export/App/lib/logback-core-1.2.3.jar:/export/App/lib/lombok-1.18.4.jar:/export/App/lib/msgpack-0.6.12.jar:/export/App/lib/netty-all-4.1.8.Final.jar:/export/App/lib/okhttp-3.6.0.jar:/export/App/lib/okio-1.11.0.jar:/export/App/lib/open-api-sdk-2.0.jar:/export/App/lib/opencsv-3.9.jar:/export/App/lib/slf4j-api-1.7.30.jar com.jd.forcebot.worker.process.WorkerEntryPoint -worker-id 0 -console-port 35501 -log-level ERROR -log-output FILE -log-path /export/Logs/forcebot-agent/forcebot-agent-worker-0.log -log-max-file-size 512 -log-total-size 2048

七、将项目所依赖的jar文件名称输出到指定文件

说明：在generate-sources阶段执行build-classpath

<build>
        <resources>
            <resource>
                <directory>src/main/resources/</directory>
                <includes>
                    <include>sunxj-dependencies.txt</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <version>2.10</version>
                <executions>
                    <execution>
                        <id>dependency-scan</id>
                        <phase>generate-sources</phase>
                        <configuration>
                            <fileSeparator>/</fileSeparator>
                            <pathSeparator>;</pathSeparator>
                            <includeScope>runtime</includeScope>
                            <outputFile>${project.basedir}/target/classes/sunxj-dependencies.txt
                            </outputFile>
                        </configuration>
                        <goals>
                            <goal>build-classpath</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
