费很大劲解决了此问题，根据自己的操作解决方法大概总结如下：

首先检查配置的JDK的路径是否正确，正确的话操作【Window】->【Preferences】-> 【Java】->【Compiler】->【JDKCompliance level】->1.4

1. 选择的版本是否是正确

2. 如果以上都检查正确的话，Preferences—>Java—>Installed JRE查看是否添加jdk；

3.如果以上正确查看windows ->preference ->AplicationServers-> tomcat -> JDK-> Tomcate JDK name；

（注意配置的是JDK非JRE）
