一、打包简介

springboot的打包方式有很多种。可以打war包，可以打jar包，可以使用jekins进行打包部署的。不推荐用war包，SpringBoot适合前后端分离，打成jar进行部署更加方便快捷。

二、自定义启动页

这样就替换了原先SpringBoot的启动样式。

三、打包配置

1、打包pom配置

<!-- 项目构建 -->
<build>
    <finalName>${project.artifactId}</finalName>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    <plugins>
        <!-- SpringBoot插件：JDK编译插件 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
        <!-- SpringBoot插件：打包 -->
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
                <executable>true</executable>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <!-- 跳过单元测试 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skipTests>true</skipTests>
            </configuration>
        </plugin>
    </plugins>
</build>

2、多环境配置

1）application.yml配置

server:
  port: 8017
spring:
  application:
    name: node17-boot-package
  profiles:
    active: dev

2）application-dev.yml配置

project:
  sign: develop

3）application-pro.yml配置

project:
  sign: product

3、环境测试接口

package com.boot.pack.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class PackController {
    @Value("${project.sign}")
    private String sign ;
    @RequestMapping("/getSign")
    public String getSign (){
        return sign ;
    }
}

四、打包执行

1、指定模块打包

mvn clean install -pl node17-boot-package -am -Dmaven.test.skip=true
生成Jar包：node17-boot-package.jar

2、运行Jar包

运行dev环境 java -jar node17-boot-package.jar --spring.profiles.active=dev 运行pro环境 java -jar node17-boot-package.jar --spring.profiles.active=pro

http://localhost:8017/getSign
dev环境打印：develop
pro环境打印：product
