SpringMVC是用junit测试

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"})
