More than one fragment with the name [spring_web] was found.

项目跑的好好的。突然之间报错，不能tomcat启动。

报错如下：

Caused by: java.lang.IllegalArgumentException: More than one fragment with the name [spring_web] was found. This is not legal with relative ordering. See section 8.2.2 2c of the Servlet specification for details. Consider using absolute ordering.

  不知所云，无从下手。

  解决方案如下：

     add <absolute-ordering /> tag to your web.xml just under the <display-name> tag. should work.

    在web.xml 文件的<display-name>的元素后面增加 <absolute-ordering/> 元素。如下：

 

<display-name>XXXX</display-name>
	<absolute-ordering/>

 

  问题解决。。。tomcat成功启动。
