问题：

在执行spring mvc的web的test模块的单元测试方法时候，报错。

报错：Error creating bean with name 'resourceHandlerMapping' defined in com.mvc.test.WebConfig: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'resourceHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: No ServletContext set

解决方案：

在spring test类上加：@WebAppConfiguration("src/main/resources")
