近公司的项目和自己的项目中都用到了spring集成junit进行单元测试，总结一下几种基本的用法：
　　1.直接对spring中注入的bean进行测试(以DAO为例)：
　　在测试类上添加@RunWith注解指定使用springJunit的测试运行器，@ContextConfiguration注解指定测试用的spring配置文件的位置
　　之后我们可以注入我们需要测试的bean进行测试，Junit在运行测试之前会先解析spring的配置文件，初始化spring中配置的bean
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:spring-config-test.xml"})
public class TestProjectDao {
@Autowired
ProjectDao projectDao;
@Test
public void testCreateProjectCode(){
long applyTime = System.currentTimeMillis();
Timestamp ts = new Timestamp(applyTime);
Map codeMap = projectDao.generateCode("5"， "8"，ts，"院内");
String projectCode = (String)codeMap.get("_project_code");
Timestamp apply_time = (Timestamp)codeMap.get("_apply_time");
System.out.print(projectCode);
System.out.print(apply_time.toString());
Assert.assertTrue(projectCode.length()==12);
}
　　2.对springMVC进行测试：
　　spring3.2之后出现了org.springframework.test.web.servlet.MockMvc 类，对springMVC单元测试进行支持
　　样例如下：
package com.jiaoyiping.baseproject;
import com.jiaoyiping.baseproject.privilege.controller.MeunController;
import com.jiaoyiping.baseproject.training.bean.Person;
import junit.framework.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.servlet.ModelAndView;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
//@ContextConfiguration(classes = {WebMvcConfig.class， MockDataConfig.class})
@ContextConfiguration(locations={"classpath:/spring/applicationContext.xml"， "classpath*:mvc-dispatcher-servlet.xml"})
public class TestMockMvc {
@Autowired
private org.springframework.web.context.WebApplicationContext context;
MockMvc mockMvc;
@Before
public void before() {
//可以对所有的controller来进行测试
mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
//仅仅对单个Controller来进行测试

}
@Test
public void testGetMenu(){
try {
System.out.println("----------------------------");
ResultActions actions =
this.mockMvc.perform(get("/menu/manage.action"));
System.out.println(status());//
System.out.println(content().toString());
actions.andExpect(status().isOk());
//            actions.andExpect(content().contentType("text/html"));
System.out.println("----------------------------");
} catch (Exception e) {
e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
}
