junit单元测试报错Failed to load ApplicationContext，但是项目发布到tomcat浏览器访问没问题

junit单元测试报错Failed to load ApplicationContext，但是项目发布到tomcat浏览器访问没问题，说明代码是没问题的，配置也没问题。开始时怀疑是我使用junit版本的问题，于是换版本，不管用；甚至一度怀疑是不是我的myeclipse没破解好，一度有卸了重装的冲动。其实都没问题，点击myeclipse最上面的project——————>clean------->勾选你的项目--------->ok；(注意不是右键maven clean），然后再测试就没问题了，我也不知道为啥，感觉好奇葩，莫名其妙

错误信息如下：
