Background: Deploy two projects at the same time as Tomcat, launch java.lang.OutOfMemoryError: PermGen space

Cause: Because there are too many jar packages for two items, the JVM explodes the default memory when loading the class file.

Workaround:

(1) Find a lot of online methods, but still can not solve my problem. My workaround is to:

Right-click eclipse Project = = "Run As===èrun configuration= look to the left of Apache Tomcat below the Tomcat...=è clicking on the right side of the argument, the VM argument inside to append the following:" Remark: size oneself according to own machine set "

-xms512m-xmx512m-xx:permsize=512m-xx:maxpermsize=1024m

Note: The size of the configuration depends on your own memory, my laptop memory is 8G
