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.spring work.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: 8017spring:  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.spring work.beans.factory.annotation.Value;import org.spring work.web.bind.annotation.RequestMapping;import org.spring work.web.bind.annotation.RestController;@RestControllerpublic 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/getSigndev环境打印：developpro环境打印：product
