3.加密后的项目需要设置javaagent来启动,启动过程中解密class,完全内存解密,不留下任何解密后的文件

4.启动加密后的jar,生成xxx-encrypted.jar,这个就是加密后的jar文件,加密后不可直接执行

5.无密码启动方式,java-javaagent:xxx-encrypted.jar-jarxxx-encrypted.jar

6.有密码启动方式,java-javaagent:xxx-encrypted.jar=‘-pwd=密码’-jarxxx-encrypted.jar

加密方法

直接增加插件即可，写在Springboot的spring-boot-maven-plugin后面即可，注意修改要加密的packages配置

          <plugin>
                <!--
1.加密后,方法体被清空,保留方法参数、注解等信息.主要兼容swagger文档注解扫描  
2.方法体被清空后,反编译只能看到方法名和注解,看不到方法体的具体内容  
3.加密后的项目需要设置javaagent来启动,启动过程中解密class,完全内存解密,不留下任何解密后的文件  
4.启动加密后的jar,生成xxx-encrypted.jar,这个就是加密后的jar文件,加密后不可直接执行  
5.无密码启动方式,java-javaagent:xxx-encrypted.jar-jarxxx-encrypted.jar  
6.有密码启动方式,java-javaagent:xxx-encrypted.jar='-pwd=密码'-jarxxx-encrypted.jar

                </executions>
            </plugin>

实践

加密的效果，将所有的方法内容都清空了

应用启动方法：

java -javaagent:proguard-demo-1.0-SNAPSHOT-encrypted.jar -jar proguard-demo-1.0-SNAPSHOT-encrypted.jar

问题

启动报错

解决办法，注释掉application的加密和jar包加密就好了
