maven springboot 分环境打包jar，根据不同环境生成不同脚本

落日映苍穹つ 2022-12-28 11:09 840阅读 0赞

## 背景 ##

我的springboot 项目要部署到多个环境，每个环境的数据库等配置都不一样，我希望不同环境打包不同的jar包，jar包名根据环境区分，并且我的项目里写了启动的shell脚本，这个shell脚本的内容根据不同环境也会不一样。

## 需求 ##

1.  按不同环境的配置来打包
2.  jar包名按不同环境来命名
3.  jar包内不能包含别的环境的配置文件，（否则反编译jar包可以看到别的环境的配置，我们公司业务是一个城市一个环境，各个城市间的配置不希望泄露）
4.  启动shell脚本中的内容会根据不同环境来修改脚本内的内容

## 实现 ##

**pom.xml 配置多个profile**

<profiles>
            <profile>
                <id>test</id>
                <properties>
                    <env>test</env>
                </properties>
            </profile>
            <profile>
                <id>handan</id>
                <properties>
                    <env>handan</env>
                </properties>
            </profile>
            <profile>
                <id>baoji</id>
                <properties>
                    <env>baoji</env>
                </properties>
            </profile>
            <profile>
                <id>eerduosi</id>
                <properties>
                    <env>eerduosi</env>
                </properties>
            </profile>
    
            <profile>
                <id>haiyan</id>
                <properties>
                    <env>haiyan</env>
                </properties>
            </profile>
            <profile>
                <id>dev</id>
                <properties>
                    <env>dev</env>
                </properties>
    
            </profile>
            <profile>
                <id>local</id>
                <properties>
                    <env>local</env>
                </properties>
                <activation>
                    <activeByDefault>true</activeByDefault>
                </activation>
            </profile>
        </profiles>

**application.properties 配置spring.profiles.active 读取pom中的环境变量**

spring.profiles.active=@env@

**pom 指定生成的jar包名**

**这样就可以分环境打包了，打包命令 mvn package -P \[环境名\]**

**或者在idea中勾选环境打包，这就相当于上面的 mvn package -P 命令：**

**光这样还是不行的，我发现jar包中会把所有的application-xxx.properties都打进去，所以打包还要排除其他环境的application-xxx.properties配置。pom添加如下配置，相当于resource目录下只要所有的xml、application.properties、application-$\{env\}.properties 文件。env就是当前打包的环境。**

***注意filtering设置true,因为application.properties文件中有变量 @env@ 要替换***

<build>
      <finalName>bus-${env}</finalName>
      <resources>
          
          <resource>
              <directory>src/main/resources/</directory>
              <filtering>true</filtering>
              <includes>
                  <include>**/*.xml</include>
                  <include>application.properties</include>
                  <include>application-${env}.properties</include>
              </includes>
          </resource>
      </resources>
     </build>

**最后我写了shell脚本，启动jar包的，但是不同环境的jar包名不一样，shell中的内容就不一样，我要用pom中的env环境变量去替换shell脚本中的字符串  
shell源码如下：**

**pom中添加如下，注意开启filtering，这个表示shell 中的 @env@ 字符串要被替换成pom profile 中设定的值**

<build>
      <finalName>bus-${env}</finalName>
      <resources>
        <resource>
            <directory>${basedir}</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.sh</include>
            </includes>
            <targetPath>${project.build.directory}</targetPath>
        </resource>
      </resources>

**这是最后打包后的shell文件内容，我们看到已经替换了**
