spring boot项目打包war包，直接放在tomcat上运行，配置详细教程，本人测试成功可用，分享于初学的朋友

1.Application必须继承SpringBootServletInitializer ，文件路径如下图

spring boot项目打包怎么包含dll文件 spring boot打包war_java

package com.java1234;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

/**
 * 打包成war包时，必须继承SpringBootServletInitializer 
 * @author yqj234
 *
 */
@SpringBootApplication
public class JxcApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(JxcApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(JxcApplication.class);
    }
}

 2.复写ServletInitializer类，继承SpringBootServletInitializer，文件路径如上图所示

package com.java1234;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(JxcApplication.class);
	}

}

3.PO.XML配置war包相关的参数

3.1  修改打包方式为war

<packaging>war</packaging>

3.2  去掉内嵌tomcate

    

<dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-web</artifactId>
             <!--忽略内嵌tomcat，打包部署到tomcat。注*本地运行的时候要把这一段忽略引入个注释掉，要不然项目启动不了 -->
            <exclusions>
                 <exclusion>
                     <groupId>org.springframework.boot</groupId>
                     <artifactId>spring-boot-starter-tomcat</artifactId>
                 </exclusion>
             </exclusions>
             <!-- 移除嵌入式tomcat插件 -->
         </dependency>

3.3 添加javax.servlet 

 

<!-- 打包成war包，必须增加如下引用javax.servlet -->
         <dependency>
             <groupId>javax.servlet</groupId>
             <artifactId>javax.servlet-api</artifactId>
             <version>3.1.0</version>
             <scope>provided</scope>
         </dependency>

3.4 添加tomcat

 

<!-- 打包成war包，必须增加如下引用tomcat api -->
         <dependency>
             <groupId>org.apache.tomcat</groupId>
             <artifactId>tomcat-servlet-api</artifactId>
             <version>9.0.41</version>
             <scope>provided</scope>
         </dependency>

3.5 其他依赖和应用，根据项目实际应用来配置

4.logback-spring.xml配置，可通过tomcat的log查看应用程序log相关数据，可方案排查问题和处理异常[war包只有tomcatlog来查看log]

spring boot项目打包怎么包含dll文件 spring boot打包war_spring_02

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
    <property name="LOG_HOME" value="var/log" />
    <!-- 控制台输出 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

            <!--<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>-->
            <!-- 控制台也要使用utf-8，不要使用gbk -->
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <!-- 按照每天生成日志文件 -->
    <appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>
            ${LOG_HOME}/myapp-training-exam-service.log
        </file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

            <!--日志文件保留天数-->
            <MaxHistory>60</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread %X{user} %X{logjson} %X{code}] %-5level %logger{50} - %msg%n
            </pattern>
            <!--<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>-->
            <charset>UTF-8</charset>
        </encoder>
        <!--日志文件最大的大小-->
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>20MB</MaxFileSize>
        </triggeringPolicy>
    </appender>

    <!-- show parameters for hibernate sql 专为 Hibernate 定制 -->
    <logger name="org.hibernate.type.descriptor.sql.BasicBinder"  level="TRACE" />
    <logger name="org.hibernate.type.descriptor.sql.BasicExtractor"  level="DEBUG" />
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.engine.QueryParameters" level="DEBUG" />
    <logger name="org.hibernate.engine.query.HQLQueryPlan" level="DEBUG" />

    <!--mybatis log configure-->
    <logger name="com.apache.ibatis" level="TRACE"/>
    <logger name="java.sql.Connection" level="DEBUG"/>
    <logger name="java.sql.Statement" level="DEBUG"/>
    <logger name="java.sql.PreparedStatement" level="DEBUG"/>

    <!-- 日志输出级别 -->
    <root level="info">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />
    </root>

</configuration>

5.application-pro.yml配置log相关的参数

spring boot项目打包怎么包含dll文件 spring boot打包war_java_03

logging:
    config: classpath:logback-spring.xml 
    level:
      org.hibernate.SQL: debug
      org.hibernate.type.descriptor.sql.BasicBinder: trace  
      dao: debug
      org:
           mybatis: debug

 

server:
  port: 8080
 
spring:
   datasource:
      driver-class-name: com.mysql.jdbc.Driver
      url: jdbc:mysql://localhost:3306/db_jxc?useUnicode=true&characterEncoding=utf-8&useSSL=false  
      username: root
      password: mysql
   jpa:
     hibernate.ddl-auto: update
     show-sql: true
   thymeleaf:
    cache: false
   logging:
    config: classpath:logback-spring.xml 
    level:
      org.hibernate.SQL: debug
      org.hibernate.type.descriptor.sql.BasicBinder: trace  
      dao: debug
      org:
           mybatis: debug    
   devtools:
    restart:
      enabled: true  #设置开启热部署

6.application.xml配置 ,可以快速区换开发环境和生产环境

spring:
    profiles:
        active: pro

7. 打包以后，直接在war复制到webapps文件夹，放文件以前，关闭tomcat,放好以后，再启动tomcat,直接通过浏览器来访问，TOMCAT的端口来文件夹来访问

注：怎么打包，请参考另一个文章，打包过程
