解决方法

1、点击项目右键，选择properties，点击Deployment Assembly，选择窗口旁边的“Add”，选择 Java China编程Build Path Entries，点击“next”，选中Junit 4，点击“finish”-->"Apply"-->"Apply and Close"

2、重启Tomcat，查看console控制台是否输出异常。ps:我的正常

总结

个人感觉是建立maven环境的项目时，Junit测试依赖没有正常添加进项目，个人测试在pom.xml里添加依赖仍不能解决问题，最终使用以上方式，成功解决。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持China编程(www.chinasem.cn)。
