SpringMVC单元测试之MockMVC，模拟登入用户

今天介绍一下springMVC的单元测试，可以参考spring官方文档进行
前提准备，springmvc的demo工程，这里就不做叙述了

单元测试类
这里的静态导入比较重要，有时候没办法自动导入的
就是下面的 import static xxx.*

另一点，
[java] view plain copy 在CODE上查看代码片派生到我的代码片
@ContextConfiguration(locations = {classpath:applicationContext.xmlclasspath:applicationContext.mvc.xml})  
代表的是加载的配置文件，可以根据需要进行添加
