1、之后有一个类似的问题有解决： http://stackoverflow.com/questions/12271187/how-to-override-web-xml-in-jetty-maven-plugin-when-filtering

2、https://vaadin.com/forum/#!/thread/9122376/9122375；

这个问题暂时没有解决。

之后换了tomcat之后问题得以解决，我想是不是由于我本机没有安装jetty的缘故。虽然在执行"mvn jetty:run"之后提示started jetty Server。但是在浏览器输入

http://localhost:8080/Spring_Struts_HibernateProject之后提交没有反应。
