Spring 常用配置小结

声明式事务管理配置：

@Transaction 注解方式：

beans.xml：

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

           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
     <strong>     <span style="font-size:14px;">http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx-3.0.xsd</span></strong>
           ">

<!-- annotation方式配置事务管理器 -->
	<tx:annotation-driven transaction-manager="mytxManager" />
	<bean id="mytxManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

***Service.java:

 

	@Transactional
	public void add(User user) {
		userDAO.save(user);
	}

	@Transactional
	public void add2(Log log) {
		logDAO.save(log);
	}

在Service层配置事物，add,add2均标注为单独的事物。

xml方式配置事务管理器：

<!-- xml方式配置事务管理器- -->
	<tx:annotation-driven />
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	<aop:config>
		<aop:pointcut id="serviceOperation"
			expression="execution(* com.bjsxt.service.*Service.*(..))" />
		<aop:advisor pointcut-ref="serviceOperation" advice-ref="txAdvice" />
	</aop:config>
	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="*" />
		</tx:attributes>
	</tx:advice>

** .properties 文件配置  

<!-- .properties 文件配置  -->
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:jdbc.properties</value>
		</property>
	</bean>

 dbcp配置 以及 sessionFactory  
 

<!-- dbcp配置 以及 sessionFactory -->

	<bean id="dataSource" destroy-method="close"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="packagesToScan">
			<list>
				<value>com.bjsxt.model</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect
				</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
	</bean>

HibernateTemplate配置：

<bean id="hibernateTem" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

properies文件：

jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/spring
jdbc.username=root
jdbc.password=root
