<!-- 如果设置排除规则 则无需添加 use-default-filters="false" -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 1.导入外部文件 -->

<!-- 3.配置jdbcTemplate 被Mybaits代替 -->
<!-- 3.配置使用Mybatis操作数据库 -->
<!-- 可以根据配置文件得到 sqlSessionFactoryBean-->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 配置配置文件位置 -->
<property name="configLocation" value="classpath:mybaits/mybaits-config.xml"></property>

<bean id="tm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="ComboPooledDataSource"></property>
</bean>
<!-- 5.基于xml配置 事务;哪些方法切入事务还要写切入点表达式 -->
<aop:config>
<!-- execution(* com.item.services.*.*(..))
1*:表示任意修饰符
2*:任意类
3*:任意方法
4..:任意参数
-->
<!-- 配置切入店 表达式 -->
<aop:pointcut expression="execution(* com.item.services.*.*(..))" id="txPoint"/>

<!-- 6.配置事务增强 事务属性 -->
<tx:advice id="txInfo" transaction-manager="tm">
<!-- 配置事务属性 -->
<tx:attributes>

<!-- 注解版 配置事务管理器 -->

<!-- </bean> -->
<!-- 2:开启基于注解的事务控制模式:依赖tx名称空间 -->
<!-- <tx:annotation-driven transaction-manager="transactionManager"/> -->
<!-- 3:给事务方法加注解 @Transactionl-->
</beans>
3.SpringMVC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"

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"/>
<!-- 指定所上传文件的总大小不能超过1G。注意maxUploadSize属性的限制不是针对单个文件,而是所有文件的容量之和 -->
<property name="maxUploadSize" value="1073741824"/>
<!--resolveLazily属性启用是为了推迟文件解析,以便在UploadController 中捕获文件大小异常-->
<property name="resolveLazily" value="true"/>
<property name="maxInMemorySize" value="4096"></property>
</bean>
<!-- 处理静态资源 -->
<mvc:default-servlet-handler/> <!-- 将静态资源的处理经由Spring MVC框架交回Web应用服务器处理 -->
<mvc:annotation-driven></mvc:annotation-driven> <!-- 表示:注解驱动开发 -->
</beans>
4.Mybaits配置:
(1).Spring整合-Mybaits: 添加在Spring 配置文件中
<!-- 3.配置jdbcTemplate 被Mybaits代替 -->
<!-- 3.配置使用Mybatis操作数据库 -->
<!-- 可以根据配置文件得到 sqlSessionFactoryBean-->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 配置配置文件位置 -->
<property name="configLocation" value="classpath:mybaits/mybaits-config.xml"></property>
<!-- 控制数据源 -->
<property name="dataSource" ref="ComboPooledDataSource"></property>
<!-- 指定 mapper的位置 路径 -->
<property name="mapperLocations" value="mybaits/mapper/*.xml"></property>
</bean>
<!-- 把每个dao接口的实现 加入到ioc容器中 -->
<bean id="" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 指定dao接口所在的包 -->
<property name="basePackage" value="com.item.dao"></property>
</bean>
(2).Mybaits配置文件:
<?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="lazyLoadingEnabled" value="true"/>
<setting name="aggressiveLazyLoading" value="false"/>
<setting name="cacheEnabled" value="true"/>
</settings>
</configuration>
(3).Dao配置文件:
<?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">
<!-- namespace:接口的全类名 ,相当于告诉配置文件是实现哪个接口的;
id:方法名,相当于配置是对某个方法的实现
resultType:返回值类型(如果为查询操作 必须指定)
#{属性名}:代表取出传递过来的某个参数的值
-->
<mapper namespace="com.item.dao.ItemDao">
<resultMap type="com.item.bean.Item" id="itemMap">
<result property="id" column="id" jdbcType="VARCHAR"/>
<result property="name" column="name" jdbcType="VARCHAR"/>
<result property="password" column="password" jdbcType="VARCHAR"/>
</resultMap>
<!--举例方法: public Item getItemById(String id); -->
<select id="getItemById" resultType="com.item.bean.Item">
select * from M_TEST where id = #{id}
</select>
</mapper>
三:测试
(1).index.jsp页面发送get请求 跳转success 获取参数
<a href="getItemById?id=001">查询数据</a>
(2).查看success是否成功显示
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>成功</h1>
