Mybatis应用（二）

springMVC中整合Mybatis:

springmvc的配置文件：

<?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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">


	<!-- 引入配置文件 -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:db.properties" />
	</bean>
	
	<context:component-scan base-package="com.hurricane.learn.concurent" />
	<mvc:annotation-driven></mvc:annotation-driven>
	<!-- 视图层配置 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/pages/" />
		<property name="suffix" value=".jsp" />
	</bean>

	<mvc:resources location="/" mapping="/res/**"></mvc:resources>

	<!-- dataSource配置 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />

	</bean>
	
	<!-- MyBatis begin -->

	</bean>

	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"/>
	</bean>
</beans>

数据库链接配置db.properties:

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
jdbc.username = root
jdbc.password = root

mybatis的sql映射文件：

<?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.hurricane.learn.concurent.dao.IndexDao">

	<select id="testMybatis" resultType="map">
		select * from stu
	</select>

</mapper>

dao层java文件：

package com.hurricane.learn.concurent.dao;

import java.util.List;
import java.util.Map;

public interface IndexDao {
	List<Map> testMybatis(Map map);
}

service层：

package com.hurricane.learn.concurent.service;

import java.util.List;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.Marker;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.hurricane.learn.concurent.dao.IndexDao;
@Component
public class IndexService {
	private static Logger logger = LoggerFactory.getLogger(IndexService.class);
	private IndexDao indexDao;
	@Autowired
	public void setIndexDao(IndexDao indexDao) {
		this.indexDao = indexDao;
	}
	
	public void testMybatis() {
		List<Map> testMybatis = indexDao.testMybatis(null);
		for (Map map : testMybatis) {
			logger.trace(map.toString());
		}
	}
}

以上。
