本文解决了一个常见的Eclipse发布项目到Tomcat时出现的java.lang.ClassNotFoundException错误，详细介绍了如何通过修改项目的Deployment Assembly设置来确保所有依赖的jar文件被正确包含。

在使用eclipse发布到tomcat时提示java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener，感觉很奇怪，于是到网站发布目录发现在WEB-INF里面没有lib目录，这就是为什么提示类没有找到的原因，导致该问题可以按照下面方法解决：

1。右键点击项目，选择properties选项

2.选择“Deployment Assembly”项，选择“Add” “”Java Build Path Entries”并选择“”Maven Depedencies”选项即可

3.重新发布就会成功

如果你是maven项目，tomcat在发布项目的时候没有同时发布maven依赖所添加的jar包， 你需要设置一下eclipse： 项目 —> 属性 -> Deployment Assembly -> Add -> Java Build Path Entries -> 选择Maven Dependencies -> Finish -> OK 把对应的Maven依赖包也发布到tomcat，调试时会自动
