公司这个项目，不是我来配置构建的，把 spring的配置什么的，和 springmvc的配置没有区分开来，都是在一个配置文件里面，也就是 springmvc 里面。和我们一般的配置不一样，我们一般配置都是配置好 spring 容器的，，然后配置好 springmvc 的分开来。可是这个项目不是这样的，，，感觉是有点乱，后期也难维护管理。。。

没办法了。这个项目，他们是没有 junit 的，估计他们不喜欢用吧。可是我是有点喜欢junit 测试的。所以想自己集成junit ，在写代码的时候，方便自己测试使用。

可是在集成的时候 junit的时候居然报错了。。。

什么意思啊。。。？百度一下，，，发现这样的问题实在是太少了。。。使用网上的办法发现也不行啊。我一点点看的时候，发现是在某个 service 类初始化的时候，报错了。这个 service implements ApplicationContextAware 这类。按理来说，应该可以获取到啊，和 junit测试看起来是没有问题的。。继续看报错信息，说是某一些报错了

@Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
    	
        ServletContext application = ((WebApplicationContext) applicationContext)
                .getServletContext();

        application.setAttribute(
                WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,
                applicationContext);
        columnServic.queryAllTopics(application);
        application.setAttribute("application_link", linkService.query());
        application.setAttribute("application_banner", bannerService.query());
        //页面底部信息
        application.setAttribute("footer", footerservice.queryFooter());
        //页面系统信息
        application.setAttribute("sysconfig", syscfgService.getSysConfig());
        initEnumStatus(application);
        initSetSafetyQuestion(application);
        initSetServiceUser(application);
        
        
    }

看到了？这里是 WebApplicationContext ，和web相关要拿到 servlet 容器相关的。我们一般都是直接获取 ApplicationContext 就可以了。而我的junit 测试，只是想测试 spring的 service 而已，并不是 controller 类。但是这里是要获取 WebApplicationContext 类的，所以执行 junit 初始化的时候获取不到就报错了。并且也试过在 junit 测试的之前，构建 WebApplicationContext ，结果也是不行的。

因此只能使用 junit的 web测试方式来了，这样应该就可以了。构建来了之后果然可以了。下面是我的 junit spring mvc 测试类

package com.mytest.junit;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import com.moneyP2P.p2p.VSFP.spring.controller.test.MyTestController;
import com.moneyP2P.p2p.VSFP.spring.service.UserBaseInfoService;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = "classpath*:config/main/spring-mvc.xml")
// 默认不回滚， 如果需要 回滚，请自己 在方法 加上 回滚， @Rollback(true) 或者是 defaultRollback = true
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false)
// extends AbstractTransactionalJUnit4SpringContextTests
public class MyJunitTest extends AbstractTransactionalJUnit4SpringContextTests {

	// @Autowired
	// private WebApplicationContext wac;

	@Autowired
	private MyTestController myTestController;

	private MockMvc mockMvc;

	@Autowired
	private UserBaseInfoService userBaseInfoService;

	@Before
	public void setup() {
		// 模拟web必须有这个 构建代码否则报错
		mockMvc = MockMvcBuilders.standaloneSetup(myTestController).build();
	}

	@Test
	public void test() {

		System.out.println("==");
		System.out.println(userBaseInfoService.queryUserById(113L).getUserName());

	}
}

这样我们写 test 方法的时候，直接就获取 spring 的bean 来测试了，或者说想 mockMVC 使用 controller 来测试也是可以的。

参考 http://andy-ghg.iteye.com/blog/1772215

@RunWith(SpringJUnit4ClassRunner.class)  
@WebAppConfiguration  
@ContextConfiguration(locations = { "classpath:applicationContext-core.xml",  
        "classpath:applicationContext-servlet.xml" })  
public class TestController {  
  
    @Autowired  
    private WebApplicationContext wac;  
  
    @Autowired  
    private SYSUserController userController;//你要测试的Controller  
  
    private MockMvc mockMvc;  
  
    @Before  
    public void setup() {  
        mockMvc = MockMvcBuilders.standaloneSetup(userController).build();  
    }  
  
    @Test  
    public void testFindPageUsers() throws Exception {  
        ResultActions ra = this.mockMvc.perform(MockMvcRequestBuilders  
                .post("/sysconfig/user/findPageUsers")  
                .accept(MediaType.APPLICATION_JSON).param("page", "1")  
                .param("limit", "10"));  
        MvcResult mr = ra.andReturn();  
        String result = mr.getResponse().getContentAsString();  
        log.info(result);  
    }  
  
}
