Eclipse报错java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener解决方案

在使用Eclipse做SSH整合时Tomcat报错

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

但是Eclipse显示已经导包成功，spring中的类也可以正常使用，

于是找到了http://bbs.csdn.net/topics/3000668792009年的神贴，按照42楼的说法是

If you're using Eclipse and Maven, then the problem is with one particular project settings option:
project properties -> Java EE Module Dependencies -> Maven Dependencies
the last option must be checked (which isn't by default).

上面说到了如果使用Eclipse就必须将项目以来的jar包添加到 Java EE Module Dependencies中，但是在新版的Eclipse中没有这个选项，因此又有Eclipse : Java EE Module Dependencies Is Replaced By Web Deployment Assembly的说明，新版的Eclipse已经使用更加灵活的Deployment Assembly替换掉了Java EE Module Dependencies，因此只要在这里添加上WEB工程中的jar包即可。效果如下图所示：

PS:关于Java EE Module Dependencies的解释：This property page lets you add a Web Library dependency to utility projects, JAR files or classpath entries. Archive dependencies will be resolved into the WEB-INF/lib folder of the web module at deployment time. Class folder dependencies will be resolved into the WEB-INF/classes folder.
