SpringBoot项目的jar包瘦身计划

 1:添加maven-dependency-plugin插件用于将引用的jar包拷贝到指定的路径,便于后续tomcat启动指定依赖包路径

<!--拷贝依赖到jar外面的lib目录-->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy</id>
            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <!--指定的依赖路径-->
                <outputDirectory>
                    ${project.build.directory}/lib
                </outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

2:编译不打jar包的pom

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <!--以下configuration内的代码是不把jar包打进去,项目直接与jar包分离-->
                <configuration>
                    <layout>ZIP</layout>
                    <includes>
                        <include>
                            <groupId>nothing</groupId>
                            <artifactId>nothing</artifactId>
                        </include>
                        <include>
                            <groupId>你项目的groupId</groupId>
                <artifactId>你项目的artifactId</artifactId>
              </include>
            </includes>
          </configuration>
</plugin>

3:然后在启动项目时指定jar包路径-Dloader.path="../lib",这样就可以达到瘦身效果了

java -Dloader.path="D:develop/shared/lib" -jar 你的jar包名字.jar
