springMVC+mybatis框架搭建

首先我们先要弄清搭建项目的一般流程,需要注意哪些方面,想要什么样的效果,自己的功能有哪些?

(假设效果:项目目录结构清晰,能够查询到本地数据库中的内容。。)

1.  工程目录结构整理清楚

在src/main/java文件夹中,新建包cn.springmvc.model(存放javabean),

                                            cn.springmvc.dao(存放spring与mybatis连接接口),

                                            cn.springmvc.service(service接口),

                                            cn.springmvc.service.impl(service接口的实现),

                                            cn.springmvc.controller(存放控制层controller)

在src/main/resource文件夹中,新建包conf(存放配置文件),

                                                   mapper(mybatis的mapper文件)

在src/test/java文件夹中,新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹(存放jsp文件)

这样项目结构基本完成了

2.  引入依赖包

打开maven的pom文件,对本次开发所需使用的架包依次导入(maven项目管理的优势)

查找依赖结构有个不错的网站,http://search.maven.org/   只要输入包名即可查找引来关系

pom.xml(包依赖)

public class User {

     private int state;
     private String nickname;
     public int getId() {
         return id;
     }
     public void setId( int id) {
         this .id = id;
     }
     public int getState() {
         return state;
     }
     public void setState( int state) {
         this .state = state;
     }
     public String getNickname() {
         return nickname;
     }
     public void setNickname(String nickname) {
         this .nickname = nickname;
     }
}

import cn.springmvc.model.User;
import cn.springmvc.service.UserService;
 
 
@Service
public class UserServiceImpl implements UserService{
 
     @Autowired
     private UserDAO userDAO;
     
     @Override
     public int insertUser(User user) {
         // TODO Auto-generated method stub
         return userDAO.insertUser(user);
     }
 
}

         <!-- 命名空间 -->

          < typeAlias alias = "User" type = "cn.springmvc.model.User" />
     </ typeAliases >
 
     <!-- 映射map -->

< mapper namespace = "cn.springmvc.dao.UserDAO" >
            
          < insert id = "insertUser" parameterType = "User" keyProperty = "id" >
              insert into days_user( 
          state,
          nickname)
          values
          (       
          #{state},
          #{nickname})
          </ insert >
          
</ mapper >



这样就完成了基本插入用户的功能!


7.  junit测试插入功能

import cn.springmvc.model.User;
import cn.springmvc.service.UserService;
 
 
 
public class UserTest {
 
private UserService userService;
     
     @Before
     public void before(){                                                                   
         @SuppressWarnings ( "resource" )
         ApplicationContext context = new ClassPathXmlApplicationContext( new String[]{ "classpath:conf/spring.xml"
                 , "classpath:conf/spring-mybatis.xml" });
         userService = (UserService) context.getBean( "userServiceImpl" );
     }
     
     @Test
     public void addUser(){
         User user = new User();
         user.setNickname( "你好" );
         user.setState( 2 );
         System.out.println(userService.insertUser(user));
     }
}



测试结果如图:


maven+springMVC+mybatis+junit详细搭建过程

即完成插入功能!
