SpringBoot打包瘦身

获取lib

先用正常方式打包 解压原始jar包 获取boot-Inf目录中的lib目录 拷贝到服务器上

打包跳过lib中的Jar包

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <mainClass>cn.duckflew.NotepadApplication</mainClass>
        <layout>ZIP</layout>
        <includes>
            <include>
                <groupId>nothing</groupId>
                <artifactId>nothing</artifactId>
            </include>
        </includes>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

选择性打包

不是lib包中所有的jar都是不频繁变动的，假设我们依赖了项目中的其他模块，那么我们需要把这些模块也全部打包进去，不适合作为lib放到服务器上面异步加载

 <configuration>
    <mainClass>com.tkelevator.RmsAdminApplication</mainClass>
    <layout>ZIP</layout>
    <includes>
        <include>
            <groupId>com.tkelevator</groupId>
            <artifactId>rms-service</artifactId>
        </include>
        <include>
            <groupId>com.tkelevator</groupId>
            <artifactId>rms-mapper</artifactId>
        </include>
        <include>
            <groupId>com.tkelevator</groupId>
            <artifactId>rms-common</artifactId>
        </include>
        <include>
            <groupId>com.tkelevator</groupId>
            <artifactId>rms-model</artifactId>
        </include>
    </includes>
</configuration>

瘦身之后的效果

可以看到，Jenkins部署的时间从之前的5分钟缩短到了1分钟不到
