spring boot jar包 瘦身

1、在瘦身之前先打出一个完整的jar包，解压后将lib全部拿出来，删除非第三方的jar （删除自己项目中的依赖包）

2、获取 功能 的maven 依赖GroupIds （红色为需要保留在jar包中的groupId字符串）

mvn dependency:tree|grep -e "compile" -e "runtime"|sed 's/|//g'|sed 's/+//g'|awk '{print $3}'|awk -F ":" '{print $1,","}'|sort|uniq|grep -vE "(com.****|common-)"|xargs

3、在maven配置文件中添加  <excludeGroupIds>

4、重新打包出一个thin jar  ，运行 java -Dloader.path=lib/ -jar demo.jar

			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<fork>true</fork>
				 	<!-- mvn dependency:tree|grep -e "compile" -e "runtime"|sed 's/|//g'|sed 's/+//g'|awk '{print $3}'|awk -F ":" '{print $1,","}'|sort|uniq|grep -vE "(com.sstc.hmis|common-)"|xargs -->
