今天这个是mybatis与spring的整合

依旧是一个查询的demo

首先是demo的结构

然后是我的jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql:///test?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=falsejdbc.username=rootjdbc.password=root

与我的实体

package com.fei.model;/** * Created by fei on 2015/9/8. */public class User {    private Integer id;    private String name;    private String password;    private Integer age;    public User(String name, String password, int age) {        this.name=name;        this.password=password;        this.age=age;    }    public User() {    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }    @Override    public String toString(){        return "User[id="+id+" , name="+name+" , password="+password+"]";    }}

这个数据库就自己弄了哈

下面是两个配置文件，分别是mybatis的与spring的，网上的整合方式有三种，我这个就做了一种

mybatis-conf.xml是这个样子的

<?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>    <mappers>        <mapper resource="mapper/userMapper.xml"/>    </mappers></configuration>

spring是这个样子的

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"       xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:aop="http://www.springframework.org/schema/aop"       xsi:schemaLocation="            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd            http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">    <context:property-placeholder location="classpath:jdbc.properties"/>    <bean id="jdbcDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"          p:driverClassName="${jdbc.driverClassName}"          p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}"></bean>    <!--        <bean id="jdbcDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">            <property name="driverClassName">                <value>com.fei</value>            </property>            <property name="url">                <value>jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=UTF-8</value>            </property>            <property name="username">                <value>root</value>            </property>            <property name="password">                <value>root</value>            </property>        </bean>    -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="jdbcDataSource"/>        <property name="configLocation" value="classpath:mybatis-config.xml"></property>    </bean>    <bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">        <property name="mapperInterface" value="com.fei.dao.UserDao"></property>        <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>    </bean></beans>

不要说看不懂这个，这里只剩下需要的了

下面就是mybatis的mapper
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.fei.dao.UserDao">    <select id="getUser" parameterType="com.fei.model.User" resultType="com.fei.model.User">    SELECT * FROM user WHERE name=#{name} AND password=#{password}    </select>    <select id="getUserById" parameterType="com.fei.model.User" resultType="com.fei.model.User">        SELECT * FROM  user WHERE id=#{id}    </select>    <insert id="addUser" parameterType="com.fei.model.User" flushCache="true">        INSERT INTO user (name,password,age) VALUES (#{name},${password},#{age})    </insert></mapper>

接下来是dao了

package com.fei.dao;import com.fei.model.User;/** * Created by fei on 2015/9/8. */public interface UserDao {    public User getUser(User user);    public User getUserById(Integer id);    public void addUser(User user);/*    public void updateUser(User user);    public void deleteUser(int UserId);*/}

这里就把程序搭建好了（没有web部分，这个就是mybatis与spring的整合而已，springmvc再说）

执行main

package com.fei.test;import com.fei.dao.UserDao;import com.fei.model.User;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * Created by fei on 2015/9/8. */public class Main {    public static void main(String[] args) {        ApplicationContext ctx=null;        ctx=new ClassPathXmlApplicationContext("application.xml");        UserDao userDao=(UserDao) ctx.getBean("userDao");/*        User user=new User("test","1234",12);        userDao.addUser(user);*/        User user=new User();        user.setName("test");        user.setPassword("1234");        User newUser=userDao.getUser(user);        System.out.println(newUser.toString());    }}

对，就是这样，简单吧
此处有demo 15kb哦，绝对可用
