java.lang.IllegalStateException: Unable to redefine classes

springboot以jar包的形式启动，目前远程热部署一部分会生效，也有的会遇见下面这种问题，请指导一下原因是什么？ HOTSECONDS: 18:29:26.630 ERROR err java.lang.IllegalStateException: Unable to redefine classes at org.hotswap.agent.config.PluginManager.hotswap(PluginManager.java:296) at com.liubs.hotdeployseconds.server.HotDeployServiceImpl.hotswapClass(HotDeployServiceImpl.java:88) at com.liubs.hotdeployseconds.server.HotDeployServiceImpl.loadNewClass(HotDeployServiceImpl.java:183) at com.liubs.hotdeployseconds.server.HotDeployServiceImpl.loadNewClassBatch(HotDeployServiceImpl.java:250) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:357) at sun.rmi.transport.Transport$1.run(Transport.java:200) at sun.rmi.transport.Transport$1.run(Transport.java:197) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:196) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:573) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:834) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.lambda$run$0(TCPTransport.java:688) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:687) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.UnsupportedOperationException: class redefinition failed: attempted to add a method at sun.instrument.InstrumentationImpl.redefineClasses0(Native Method) at sun.instrument.InstrumentationImpl.redefineClasses(InstrumentationImpl.java:170) at org.hotswap.agent.config.PluginManager.hotswap(PluginManager.java:292) ... 20 more

Java几？如果是Java8那就是XXaltjvm=dcevm 没加，或者没生效，Java8以上那就是没按文档装jdk

[majiatao]

java8 181版本 我刚测试貌似是因为存在 private static final Logger logger=LoggerFactory.getLogger(XxxController.class); 的问题，是存在static静态变量就不可以嘛？

Java几？

[Liubsyy]

不是，随意改代码都没问题的，包括增删字段方法类

[majiatao]

应该是生效的，因为java文件不存在静态变量的可以远程热部署成功的，存在静态变量的就不可以，

Java几？如果是Java8那就是XXaltjvm=dcevm 没加，或者没生效，Java8以上那就是没按文档装jdk

[Liubsyy]

跟静态变量也没关系的，增加静态变量只是触发类的静态初始化，不加则不触发

Reference

那这个的原因还能是出现在哪里呢？

就是没生效，ps -ef｜grep java把jvm参数贴一下吧

重新把server端放在运行目录下 就可以了，谢谢大佬
