使用junit测试SpringMVC

架包支持：junit.jar;org.springframework.test-3.1.0.RELEASE.jar


测试Dao基础类：JUnitDaoBase

package test.test;
import javax.annotation.Resource;
import javax.sql.DataSource;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
/**
 * <b>Summary: </b> TODO Junit 基础类,加载环境 
 * <b>Remarks: </b> TODO DAO测试基础类
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/config/applicationContext.xml"})
public  class JUnitDaoBase extends AbstractTransactionalJUnit4SpringContextTests {

	/**
	 * <b>Summary: </b> 复写方法 setDataSource
	 * 
	 * @param dataSource
	 * @see org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests#setDataSource(javax.sql.DataSource)
	 */
	@Override
	@Resource(name = "myDataSource")
	public void setDataSource(DataSource dataSource) {
		// TODO Auto-generated method stub
		super.setDataSource(dataSource);
	}
}

具体dao 测试继承daoBaseTest就可以了

package test.java.dao;

import java.util.List;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import com.pinfang.dao.UserDao;
import com.pinfang.vo.User;

import test.test.JUnitDaoBase;
/**
 * dao层测试例子
 * @author fule
 *
 */
public class UserDaoTest extends JUnitDaoBase {
	@Autowired
	private UserDao userDao;

	

	@Test
	public void testUserDao() {
		User user = new User();
		user.setPassword("123456");
		user.setName("大妈");
		user.setSex(1);
		//System.out.println(userDao.findOnValidate(user).getMark());
		List<User> list = userDao.getAll();
		System.out.println(list);
		//System.out.println(userDao.findOneByName("张三s"));
		//System.out.println(userDao.addUser(user));
	}
}

action层测试基础类：JUnitActionBase

package test.test;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.junit.BeforeClass;
import org.springframework.mock.web.MockServletContext;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.XmlWebApplicationContext;
import org.springframework.web.servlet.HandlerAdapter;
import org.springframework.web.servlet.HandlerExecutionChain;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter;
import org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping;

/**
 * JUnit测试action时使用的基类
 * 
 * @author fule
 * 
 */
public class JUnitActionBase {
	private static HandlerMapping handlerMapping;
	private static HandlerAdapter handlerAdapter;

	/**
	 * 读取配置文件
	 */
	@BeforeClass
	public static void setUp() {
		if (handlerMapping == null) {
			String[] configs = { 
					"file:src/config/applicationContext.xml" };
			XmlWebApplicationContext context = new XmlWebApplicationContext();
			context.setConfigLocations(configs);
			MockServletContext msc = new MockServletContext();
			context.setServletContext(msc);
			context.refresh();
			msc.setAttribute(
					WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,
					context);// TODO
			handlerMapping = (HandlerMapping) context
					.getBean(DefaultAnnotationHandlerMapping.class);

			handlerAdapter = (HandlerAdapter) context
					.getBean(context
							.getBeanNamesForType(AnnotationMethodHandlerAdapter.class)[0]);

			// handlerAdapter = (HandlerAdapter) context.getBean(context
			// .getNamespace());
		}
	}

	/**
	 * 执行request请求的action
	 * 
	 * @param request
	 * @param response
	 * @return
	 * @throws Exception
	 */
	public ModelAndView excuteAction(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		// 这里需要声明request的实际类型，否则会报错
		request.setAttribute(HandlerMapping.INTROSPECT_TYPE_LEVEL_MAPPING, true);
		HandlerExecutionChain chain = handlerMapping.getHandler(request);
		ModelAndView model = null;
		try {
			model = handlerAdapter
					.handle(request, response, chain.getHandler());
		} catch (Exception e) {
			e.printStackTrace();
		}
		return model;
	}
}

测试action类继承它就可以了

package test.java.action;

import org.junit.Assert;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.web.servlet.ModelAndView;

import com.pinfang.logic.service.UserService;

import test.test.JUnitActionBase;
/**
 * action测试列子
 * @author fule
 *
 */
public class UserActionTest extends JUnitActionBase {
@Autowired UserService service;
	@Test
	public void testUserShow() throws Exception{
		MockHttpServletRequest request = new MockHttpServletRequest();
		MockHttpServletResponse response = new MockHttpServletResponse();
		request.setServletPath("/userManager/user.show");
		request.addParameter("name", "张三");
		request.addParameter("password", "123456");
		request.setMethod("post");
		request.setAttribute("msg", "测试action成功");
		final ModelAndView mav = this.excuteAction(request, response);
		Assert.assertEquals("userManager/userlist", mav.getViewName());
		String msg=(String)request.getAttribute("msg");
		System.out.println(msg);
	}
}

配置文件记得声明两个bean:

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<bean  class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

Spring读取WEB-INF下配置文件的方法：
配置文件放在class目录下：

view plaincopyprint?
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("springMVCForm-servlet.xml");  

WEB-INF下：

[java] view plaincopyprint?
ApplicationContext applicationContext = new FileSystemXmlApplicationContext("WebContent/WEB-INF/springMVCForm-servlet.xml"); 

多个文件可用*表示：

[java] view plaincopyprint?
ApplicationContext applicationContext = new FileSystemXmlApplicationContext("WebContent/WEB-INF/springMVCForm-*.xml");  

注解方式：
配置文件放在class目录下：

[java] view plaincopyprint?
@ContextConfiguration(locations={"classpath:springMVCForm-servlet.xml"})  

WEB-INF下：

view plaincopyprint?
@ContextConfiguration(locations={"file:WebContent/WEB-INF/springMVCForm-servlet.xml"})
