spring事务管理（声明式）

1、实现类：

package cn.com.gan.spring.database;

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

import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.DefaultTransactionDefinition;

import javax.sql.DataSource;

public class UserDao implements IUserDao {
	// private DataSource dataSource;
	private JdbcTemplate jdbcTemplate;
   // private PlatformTransactionManager tm;
   //private DefaultTransactionDefinition df;
	public void setDataSource(DataSource dataSource) {
		jdbcTemplate = new JdbcTemplate(dataSource);
		//tm=new DataSourceTransactionManager(dataSource);
		//df=new DefaultTransactionDefinition();
		//df.setPropagationBehavior(DefaultTransactionDefinition.PROPAGATION_REQUIRED);
	}
	@Override
	public List<User> find(String name) {
		List<Map> list = jdbcTemplate
				.queryForList("select * from user where name='" + name + "'");
		User user = null;
		List<User> relist=new ArrayList<User>();
		for (Map map : list) {
			user = new User();	
			user.setName(map.get("name").toString());
			user.setAge(Short.parseShort(map.get("age").toString()));
			relist.add(user);
		}
		return relist;
	}
	@Override
	public void insert(User user) {
		//TransactionStatus ts=tm.getTransaction(df);
		
	    jdbcTemplate.update("insert into user(name,age) values(?,?)",
				new Object[] { user.getName(), user.getAge() });
	    jdbcTemplate.update("insert into user(name,age) values(?,?)",
				new Object[] { user.getName(), user.getAge() });
	
	    //tm.commit(ts);
	}
}

其中貌似insert加入try catch 否则事务失效。例如这样

package cn.com.gan.spring.database;

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

import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.DefaultTransactionDefinition;

import javax.sql.DataSource;

public class UserDao implements IUserDao {
	// private DataSource dataSource;
	private JdbcTemplate jdbcTemplate;
   // private PlatformTransactionManager tm;
   //private DefaultTransactionDefinition df;
	public void setDataSource(DataSource dataSource) {
		jdbcTemplate = new JdbcTemplate(dataSource);
		//tm=new DataSourceTransactionManager(dataSource);
		//df=new DefaultTransactionDefinition();
		//df.setPropagationBehavior(DefaultTransactionDefinition.PROPAGATION_REQUIRED);
	}
	@Override
	public List<User> find(String name) {
		List<Map> list = jdbcTemplate
				.queryForList("select * from user where name='" + name + "'");
		User user = null;
		List<User> relist=new ArrayList<User>();
		for (Map map : list) {
			user = new User();	
			user.setName(map.get("name").toString());
			user.setAge(Short.parseShort(map.get("age").toString()));
			relist.add(user);
		}
		return relist;
	}
	@Override
	public void insert(User user) {
		//TransactionStatus ts=tm.getTransaction(df);
	   try{	
	    jdbcTemplate.update("insert into user(name,age) values(?,?)",
				new Object[] { user.getName(), user.getAge() });
	    jdbcTemplate.update("insert into user(name,age) values(?,?)",
				new Object[] { user.getName(), user.getAge() });
	}catch(Exception e){
          e.printStackTrace();
         return ;
        }
	    //tm.commit(ts);
	}
}

好像事务就失效了。
2、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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
	<!--
		<bean id="ds"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	-->
	<bean id="ds" class="org.apache.commons.dbcp.BasicDataSource">

			<value>jdbc:mysql://localhost/test</value>
		</property>
		<property name="driverClassName">
			<value>com.mysql.jdbc.Driver</value>
		</property>
		<property name="username">
			<value>root</value>
		</property>
		<property name="password">
			<value>pass</value>
		</property>
	</bean>
	<bean id="userdao" class="cn.com.gan.spring.database.UserDao">
		<property name="dataSource">
			<ref local="ds" />
		</property>
	</bean>
	<bean id="tranmanager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="ds"></property>
	</bean>
	<bean id="userdaoproxy"
		class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
		<property name="proxyInterfaces">
			<value>cn.com.gan.spring.database.IUserDao</value>
		</property>
		<property name="target" ref="userdao"></property>
		<property name="transactionManager">
			<ref local="tranmanager" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="insert">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>
</beans>

getBean的时候获取代理类，及userdaoproxy。
或者

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

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

	-->
	<property name="interceptorNames">

</beans>
