使用maven管理后,依然找不到需要的jar包

使用maven管理后，依然报错，找不到，比如如下错误
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

方法如下

1) Open the project‘s properties (e.g., right-click on the project‘s name in the project explorer and select "Properties")
2) select "Deployment Assembly"
3) Click the "Add..." button on the right margin
4) Select "Java Build Path Entries" from the menu of Directive Type and click "Next"
5) Select "Maven Dependencies" from the Java Build Path Entries menu and click "Finish".
