平时对junit测试service/DAO层已经很熟悉不过了，如果不了解，可以猛戳这里，但是我们要测试controller层，不能总重启服务器吧，（重启tomcat好慢的飘过，别。。。别走啊），那么我们就用junit4模拟请求，测试controller层的方法。

代码1：直接Controller调用方法

import static org.junit.Assert.*;import java.sql.SQLException;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.mock.web.MockHttpServletRequest;import org.springframework.mock.web.MockHttpServletResponse;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.zz.login.web.LoginController;/** * @author zhzh * 2015-4-7 */@RunWith(SpringJUnit4ClassRunner.class)  @ContextConfiguration({"classpath*:/beans.xml","classpath*:/spring-mvc.xml"})  public class TestController {	// 模拟request,response      private MockHttpServletRequest request;      private MockHttpServletResponse response;             // 注入loginController      @Autowired      private LoginController loginController ;            // 执行测试方法之前初始化模拟request,response      @Before        public void setUp(){            request = new MockHttpServletRequest();              request.setCharacterEncoding("UTF-8");              response = new MockHttpServletResponse();          }             /**      *       * @Title：testLogin      * @Description: 测试用户登录        */      @Test      public void testLogin() {           try {          	request.setParameter("userName", "admin");        	request.setParameter("password", "2");            assertEquals("login",loginController.loginIn(request,response)) ;          } catch (Exception e) {              e.printStackTrace();          }      }  }

代码2：调用请求路径

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;import static org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup;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.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.transaction.annotation.Transactional;import org.springframework.web.context.WebApplicationContext;/** * @author zhzh * 2015-4-7 */@RunWith(SpringJUnit4ClassRunner.class)  @WebAppConfiguration  @ContextConfiguration({"classpath*:/beans.xml","classpath*:/spring-mvc.xml"}) //当然 你可以声明一个事务管理 每个单元测试都进行事务回滚 无论成功与否  @TransactionConfiguration(defaultRollback = true)  @Transactional public class TestController2 {	@Autowired      private WebApplicationContext wac;        private MockMvc mockMvc;         @Before      public void setup() {           this.mockMvc = webAppContextSetup(this.wac).build();      }         @Test      public void testLogin() throws Exception {          mockMvc.perform((post("/loginTest").param("userName", "admin").param("password", "1"))).andExpect(status().isOk())                  .andDo(print());      }         /*@Test      //有些单元测试你不希望回滚      @Rollback(false)  	public void testInsert() throws Exception {  	    mockMvc.perform((post("/insertTest"))).andExpect(status().isOk())  	            .andDo(print());  	} */}

注意：import static 的spring类

LoginController代码片段

/**	 * 登录入口	 * @param request	 * @param response	 * @return	 */	@RequestMapping(value = http://www.mamicode.com/"/loginTest", method = RequestMethod.POST)	public String loginTest(HttpServletRequest request,HttpServletResponse response){		String account = request.getParameter("userName");		String password = request.getParameter("password");		if (account.equals("admin")&&password.equals("1")){			return "index";		}else{			return "login";		}	}
