how to set java_opts in eclipse
提问by CodeMed
I need to set JAVA_OPTSin a development machine running windows 7 home edition and tomcat 7 server. I am getting permgen out of memoryerror when running spring-mvcweb applications from eclipse. I want to enable classunloading so that memory gets freed up over the course of repeated reloading of web applications. I also want to increase the amount of memory available.
我需要JAVA_OPTS在运行 Windows 7 家庭版和tomcat 7 server. permgen out of memory运行spring-mvcWeb 应用程序时出现错误eclipse。我想启用class卸载，以便在重复重新加载 Web 应用程序的过程中释放内存。我还想增加可用内存量。
Can someone show me explicitly how to do this, in step by step form?
有人可以一步一步地明确告诉我如何做到这一点吗？
Do I set a windows system environmental variable? Do I run something from the command line? What specifically will my commands look like in code?
我是否设置了 Windows 系统环境变量？我从命令行运行一些东西吗？我的命令在代码中具体是什么样的？
Here is what I have so far (all on the same line):
这是我到目前为止所拥有的（都在同一行）：
JAVA_OPTS=XX:MaxPermSize=128MXX:+CMSClassUnloadingEnabledXX:+CMSPermGenSweepingEnabledXms256m -Xmx512m

In eclipse go to your launch configuration of the server (something like Apache Tomcat > Tomcat v7.0 Server at localhost) and add jvm arguments in the Argumentstab in the VM argumentsfield.
在 Eclipse 中，转到服务器的启动配置（类似于Apache Tomcat > Tomcat v7.0 Server at localhost）并Arguments在VM arguments字段的选项卡中添加 jvm 参数。
If you are using eclipsetotaletomcat plugin then go to
如果您使用的是eclipsetotaletomcat 插件，请转到
Preferences > Tomcat > JVM Settings > Append to JVM Paramaters
and add them one by one.
并一一添加。
EDIT(run as > run on server)
编辑（运行方式 > 在服务器上运行）
