1  tomcat 之前能启动过几天不能启动------------不管报什么错查看端口是否占用


2 同样的maven项目，过了几天就无法build了
报错：

将下面的参数写在：windows preferences java installed jars   edit的default vm args中
-Xms512m -Xmx2048m -XX:PermSize=2048m -XX:MaxPermSize=512m -XX:NewSize=128m
删除maven本地库中的相应的jar，
再次运行如果是系统的jar出错，查看本地库中下载的jar是否正常。

eclipse增加内存

eclipse安装后，在安装目录有个config.ini文件，内容如下：
-vmargs
-Xms40m
-Xmx256m
