SSM整合与基本配置

Posted 2020-09-30

Spring+SpringMVC+Mybatis整合

 

一．首先创建三个文件夹用户存放Spring+SpringMVC+Mybatis，如下图 

 

 

Mybatis文件夹下的配置

1.config文件内容

 

<?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>

    <!--配置指向mappe.xml的路径-->

    <mappers>

        <mapper resource="mybatis/UserMapper.xml"/>

    </mappers>

 

</configuration>

2.UserMapper.xml文件配置

 

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE mapper

        PUBLIC "-//er 3.0//EN"

        "http://mybatimybatis.org//DTD Mapps.org/dtd/mybatis-3-mapper.dtd">

<!--指向Dao层-->        

<mapper namespace="cn.yunhe.dao.UserMapper">

    <!--用户信息查询-->

    <select id="selectUser" parameterType="int" resultType="map">

        select * from user where id = #{id}

    </select>

 

 </mapper>

Spring文件夹下的文件配置

3.Spring-mybatis.xml文件配置

 

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

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

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

 

    </bean>

 

    <!--配置spring的事物管理器-->
