SSM架構整合之配置檔案的定義

一、mybatis所需要的配置檔案

1，mybatis映射檔案 

<strong><?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="接口的全限定性名稱">

	<insert id="對應的方法名稱">
                 <!-- sql語句-->
		insert into student(name,age) values(#{name},#{age})
	</insert>
	
</mapper></strong>

2，mybatis主配置檔案 

<strong><?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>
	<!-- 為實體類指定别名 -->
	<typeAliases>
		<package name="com.bjpowernode.beans"/>
	</typeAliases>
	
	<!-- 注冊映射檔案 -->
	<mappers>
		<!-- 映射檔案的名字和實體類的名字相同的時候才能這樣寫
				要是不同，就要用 mapper标簽-->
		<package name="com.bjpowernode.dao"/>
	</mappers>
	
</configuration></strong>

二、Spring架構所需配置檔案

1，Spring-db 

<strong><?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"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="

        http://www.springframework.org/schema/aop/spring-aop.xsd">
        
        <!-- 注冊C3P0資料源 -->
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        	<property name="driverClass" value="${jdbc.driver}"/>
        	<property name="jdbcUrl" value="${jdbc.url}"/>
        	<property name="user" value="${jdbc.user}"/>
        	<property name="password" value="${jdbc.password}"/>
        </bean>
        
        <!-- 注冊屬性檔案 -->
        <context:property-placeholder location="classpath:resources/jdbc.properties"/>
        
</beans></strong>

2，Spring-mybatis 

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

        http://www.springframework.org/schema/aop/spring-aop.xsd">
        
        <!-- 注冊SqlSessionFactory -->
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        	<property name="configLocation" value="classpath:resources/mybatis.xml"/>
        	<property name="dataSource" ref="dataSource"/>
<!-- 當mybatis的xml檔案和mapper接口不在相同包下時，需要用mapperLocations屬性指定xml檔案的路徑. *是個通配符，代表所有的檔案，**代表所有目錄下 -->   
          <property name="mapperLocations" value="classpath:com/wj/mapper/*.xml" /> 
        </bean>
        
        <!-- 生成Dao的代理對象 -->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        	<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        	<property name="basePackage" value="com.bjpowernode.dao"/>
        </bean>
</beans></strong>

3，Spring-Service 

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

	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="

</beans>
</strong>

4，Spring-tx 

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

        <!-- 注冊切面 -->
        <bean id="myAspect" class="com.bjpowernode.aspect.MyAspect"/>

三、SpringMVC所需配置 

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