Answer 3

这个原因是因为没有编译好导致的，你把公正用到jar包都remove掉，然后应用修改，重新加进来看看。

Answer 4

谁能给我发一套jar包，我都换了一堆jar包了 谁有ssh完整版jar包能发下[email protected]  谢谢了

Answer 5

修改类文件或者配置文件后，应该重启 tomcat 服务，而不是使用其 reloadable 功能！

Answer 6

这个表示持久堆内存溢出，持久堆是存放类信息、方法信息的空间，由于热部署的次数太多，导致该内存区中的内存耗尽，重启 tomcat 服务就可以了。

Answer 7

后面又报了恶心的错误，最终全是jar包的问题。现在好了。
