解决方案:
造成这种错误原因是的支撑Tomcat运行的JDK版本与支撑application运行的JDK版本不一致导致的.
把它们的JDK本改成一致步骤如下:
1.Window --> Preferences -->Java --> compiler中的compiler compliance level对应的下拉菜单中选择JDK版本.
2.Window --> Preferences -->MyEclipse --> Servers -->Tomcat --> Tomcat n.x -->JDK中的Tomcat JDK name下的下拉菜单中选择自身电脑上安装的JDK版本(必需与步骤1中的JDK版本一致).
