如何写单元测试

[cloud13th]

jeesite旧版中，如何使用Junit写controller和service的单元测试用例呢？
以下是我写的单元测试例子：
`
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:/applicationContext.xml"})
public class HousingTypeRestTest extends AbstractJUnit4SpringContextTests {

@Autowired
protected WebApplicationContext context;

private MockMvc mockMvc;

@Before
public void init() {
    mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
}

@SneakyThrows
@Test
@Rollback
public void getCommentInfos() {
    mockMvc.perform(
            MockMvcRequestBuilders.get("/rest/abc")
                    .accept(APPLICATION_JSON_UTF8)
    )
            .andDo(print())
            .andExpect(status().isOk())
            .andReturn();
}

}
对应的controller代码为
@RequestMapping("/rest")
@controller
public class HelloRest {

@RequestMapping(value = "/abc")
@ResponseBody
public String hello() {
    return "Hello World.";
}

}
但是启动之后，报错误信息为：
java.lang.IllegalStateException: Failed to load ApplicationContext

at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:124)
at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:83)
at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:117)

...
`

查找了下，发现web.xml中配置的servlet为org.glassfish.jersey.servlet.ServletContainer，但是官方也是这么配置的，所以咱也不敢乱动。

so，请问有解决办法么？
