在tomcat设置页面点击open launch configuration->Arguments->VM arguments里面加上这段 -Xms512m -Xmx768m -XX:CompileThreshold=8000 -XX:PermSize=128m -XX:MaxPermSize=256m -Xverify:none -Djavax.xml.soap.MessageFactory="com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl" -Djavax.xml.soap.MetaFactory="com.sun.xml.messaging.saaj.soap.SAAJMetaFactoryImpl"，和原来的用空格隔开
