關於spring mvc+mybatis+junit單元測試

這次測試的目的是直接在單元測試中測試Controller的類。

在單元測試的時候一定要保證spring部分和mybatis部分的代碼編寫全部正確，即便是沒有用到的一些bean和一些mybatis的增刪改查。junit會掃描全部的內容，遇到掃描錯誤的就會報出。

先看applicationContext文件

Controller部分：TestController.java

package com.ewell.home.controller;

import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.ewell.home.service.UserService;
import com.ewell.home.vo.User;

@Controller
@RequestMapping("/TestController")
public class TestController {
	
	@Autowired
	private UserService userService;
	
	@RequestMapping("/getUser")
	@ResponseBody
	public String getUser(String id){
		String massage = "";
		Map<String,Object> map = new HashMap<String,Object>();
		User user = null;
		user = userService.getUser(Integer.parseInt(id));
		
		if(null == user){
			massage = "error";
		}else{
			massage = "success";
		}
		return massage;
	}
}

ServiceImpl文件

package com.ewell.home.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.ewell.home.service.UserService;
import com.ewell.home.vo.User;
import com.ewell.isd.mybatis.dao.MyBatisDAO;

@Service
public class UserServiceImpl implements UserService{
	@Autowired
	private MyBatisDAO myBatisDAO;
	
	@Override
	public User getUser(Integer id) {
		// TODO Auto-generated method stub
		return (User)myBatisDAO.findForObject("getUser",id);
	}
}

單元測試部分

基類BaseSpringTestCase

package com.ewell;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

	@RunWith(SpringJUnit4ClassRunner.class)
	@ContextConfiguration(locations={"classpath:applicationContext.xml"})

	// 添加註釋@Transactional 回滾對數據庫操作  
	@Transactional
	public class BaseSpringTestCase {
		
	}

測試類：TestUser

package com.ewell;

import static org.junit.Assert.assertEquals;

import java.sql.SQLException;

import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;

import com.ewell.home.controller.TestController;
import com.ewell.home.service.UserService;
import com.ewell.home.vo.User;


public class TestUser extends BaseSpringTestCase{
	private MockHttpServletRequest request;
	private MockHttpServletResponse response;
	private UserService userService;
	@Autowired
	private TestController testController ;
    @Before
    public void before(){                                                                   
/*        ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:applicationContext.xml"
                ,"classpath:mybatis/mybatis-sqlserver.xml"});*/
        request = new MockHttpServletRequest();    
        request.setCharacterEncoding("UTF-8");    
        response = new MockHttpServletResponse();
    }
     
    @Test
    public void addUser(){
        User user = new User();
		String id= "23" ;
		assertEquals("loginok",testController.getUser(id)) ;
    }
}
