Eclipse中tomcat加大内存

一、eclipse老是报内存溢出，加大内存
tomcat maven plugin 设置启动内存

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <version>1.1</version>
    <configuration>
	<path>/</path>
	<systemProperties>
	    <JAVA_OPTS>-Xms512m -Xmx1024m -XX:MaxPermSize=256m</JAVA_OPTS>
	</systemProperties>
    </configuration>
