Spring+Springmvc+Mybatis+junit+log4j集成的一个小案例

1.     本文主要内容

搭建一个整合了Spring、SpringMVC和mybatis的项目框架，同时我也添加了一些示例功能在里面，将主要的功能填充起来。

因为springMVC是基于spring的原因，所以这三个框架整合实际上就是两个框架的整合。

此外，我还整合了log4j用于日志的输出，整合junit用于单元测试。

2.     搭建springmvc框架

首先是导入相关jar包，这里我使用的maven管理这些jar包，不做解释。我是采用xml配置方式搭建框架。直接代码展示。

3．代码展示

1).jdbc.properties //数据库连接配置文件，MySQL

#mysql jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/emps?characterEncoding=utf8 jdbc.username=root jdbc.password=123

2).applicationContext\_User.xml//主要用来配置数据库，事务管理等

6).log4j.properties//日志配置文件

7).Java代码

Controller层部分代码

private UserService userService;

@RequestMapping("/userList")
    public String list(ModelMap model) {
        model.put("users", userService.getUserEntities());
        System.out.println(userService.getUserEntities().toString());
        return "list";
    }

实体部分代码//setter和getter方法自动生成或者手动生成

private String userId;
    private String userName;
    private String password;
    private String sex;
    private String email;

接口代码

public interface UserMapper {
        //根据用户ID获取用户信息   public  UserEntity getUserEntityById(String userId);
        //获取用户所有的用户信息    public List<UserEntity> getUserEntities();
        //插入用户信息    public int insertUser(UserEntity userEntity);
    }

service层代码

public interface UserService {
        //根据用户ID获取用户信息     UserEntity getUserEntityById(String userId);
        //获取用户所有的用户信息     List<UserEntity> getUserEntities();
        //插入用户信息     UserEntity insertUserEntity(UserEntity userEntity);
    }

serviceImpl代码

public class UserServiceImpl implements UserService {
        @Autowired     private UserMapper userMapper;
        public UserMapper getUserMapper() {
            return userMapper;
        }
        public void setUserMapper(UserMapper userMapper) {
            this.userMapper = userMapper;
        }
        @Override     public UserEntity getUserEntityById(String userId) {
         return this.userMapper.getUserEntityById(userId);
        }
        @Override     public List<UserEntity> getUserEntities() {
            return this.userMapper.getUserEntities();
        }
        @Override     public UserEntity insertUserEntity(UserEntity userEntity) {
            this.userMapper.insertUser(userEntity);
          return getUserEntityById(userEntity.getUserId());
        }
    }

测试代码

@RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration({
       "classpath:config/applicationContext_User.xml"})
    public class STest {
        Logger log = LoggerFactory.getLogger(this.getClass());
    
        @Before     public void before(){
        }
    
        @org.junit.Test     public void testShowUser() throws Exception {
           log.info("start");
            ApplicationContext ctx = new ClassPathXmlApplicationContext("config/applicationContext_User.xml");
            UserMapper userMapper  = (UserMapper) ctx.getBean("userMapper");
            List<UserEntity> u =  userMapper.getUserEntities();
            UserEntity us = userMapper.getUserEntityById("2");
            System.out.println(u.toString());
            System.out.println(us.toString());
            log.info("成功");
        }
      @org.junit.Test   public void addUser(){
            log.info("开始执行插入操作");
            ApplicationContext ctx = new ClassPathXmlApplicationContext("config/applicationContext_User.xml");
            UserMapper userMapper  = (UserMapper) ctx.getBean("userMapper");
            UserEntity user = new UserEntity();
            user.setUserId("10");
            user.setUserName("Tim");
            user.setPassword("12345");
            user.setSex("男");
            user.setEmail("920449464@qq.com");
            log.info("插入成功");
           System.out.println(userMapper.insertUser(user));
        }
    }
