SpringMvc4.0.0+Spring4.0.0+Mybatis3.2.7整合开发

环境: Eclipse mars.2 + jdk1.8 + SpringMvc4.0.0+Spring4.0.0+Mybatis3.2.7整合开发

 

导入jar包：

mysql数据库驱动包

c3p0包

Mybatis

  mybatis-3.2.7.jar

   lib/*.jar

Spring

  libs/*.jar(包含了springmvc的jar包)

Mybatis与Spring整合额外需要的包 mybatis-spring-1.2.2.jar

 

 

建好项目结构包

com.zns.blog.controller

com.zns.blog.service

com.zns.blog.mapper

com.zns.blog.domain

 

 

假设数据库有一张用户表 就2个字段 主键 和 账号

 

新建User类

package com.zns.blog.domain;


public class User {
    private int UserID;
    private String UserAccount;
    
    public int getUserID() {
        return UserID;
    }
    public void setUserID(int userID) {
        UserID = userID;
    }
    public String getUserAccount() {
        return UserAccount;
    }
    public void setUserAccount(String userAccount) {
        UserAccount = userAccount;
    }        
}

 

 

新建UserMapper接口

package com.zns.blog.mapper;

import com.zns.blog.domain.User;

public interface UserMapper {
    public User getByID(int id) throws Exception;
}

 

 

新建UserMapper.xml

xml version="1.0" encoding="UTF-8" ?>
DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.zns.blog.mapper.UserMapper">
    <select id="getByID" parameterType="int"
        resultType="com.zns.blog.domain.User">
        select * from User where UserID=#{UserID}
    select>
mapper>

 

 

src下增加jdbc.properties文件

jdbc.driver = com.mysql.jdbc.Driver

jdbc.url = jdbc:mysql://localhost:3306/mydb

jdbc.user = root

jdbc.password =123456

 

新建一个config资源文件夹  

然后在config下新增spring和mybatis文件夹

 

在mybatis下新建mybatis-config.xml

xml version="1.0" encoding="UTF-8" ?>
DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
  
<configuration>
  
  
  
  
  <settings>
    <setting name="callSettersOnNulls" value="true"/>
  settings>
  
configuration>

 

 

在spring下新建applicationContext.xml

xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="user" value="${jdbc.user}"/>

    bean>
    
      
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" />  
          
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml">property>  
    bean>  
    
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    bean>
    
     
    
    
    
    
    
beans>

 

 

在spring下新建springmvc.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

新建UserService

package com.zns.blog.service;

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

import com.zns.blog.domain.User;
import com.zns.blog.mapper.UserMapper;

@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;
    public User getByID(int id) throws Exception{
          return userMapper.getByID(id);
    }
}

 

 

 

新建一个UserController

package com.zns.blog.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.zns.blog.domain.User;
import com.zns.blog.service.UserService;

@Controller
@RequestMapping("User")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("Detail")
    public ModelAndView Detail() throws Exception {
        User user = userService.getByID(1);
        System.out.println(user);
        ModelAndView modelAndView = new ModelAndView();
        //相当于加入到request域
        modelAndView.addObject("userInfo", user);
        modelAndView.setViewName("/xxx.jsp");
        return modelAndView;
    }
}

 

 

启动测试访问/项目名/User/Detail 可以看到打印的用户信息  基本整合完毕
