如何使用Junit做单元测试，急

guduying

我的测试如下，注解部分：
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextHierarchy({
        //@ContextConfiguration(classes = WebApplicationContext.class),
        @ContextConfiguration("file:src/main/resources/public/beans.xml"),
        @ContextConfiguration("file:src/main/resources/public/spring-mvc.xml")
})
@TestPropertySource(locations = { "file:src/main/webapp/JE/data/config/datasource.properties",
        "classpath:jdbc.properties", "classpath:redis.properties", "classpath:sysconfig.properties" })
一直是不成功的
