JTA分布式事务实战(atomikos)

最近需要用到分布式事务，研究了下jta，使用了atomikos这个jta的实现，使用的是spring3.0，废话少说，直接贴代码。

1.使用如下jar包

atomikos-util.3.7.0.jar

cglib-nodep-2.2.2.jar

transactions-3.7.0.jar

transactions-api-3.7.0.jar

transactions-jdbc-3.7.0.jar

transactions-jta-3.7.0.jar

2.spring配置文件如下:

<?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:jee="http://www.springframework.org/schema/jee"  
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"  
    default-lazy-init="true">  
  
  	
  	<context:component-scan base-package="com.atom.jta.test" />
  
    <!-- atomikos事务管理器 -->  
    <bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"  
        init-method="init" destroy-method="close">  
        <description>UserTransactionManager</description>  
        <property name="forceShutdown">  
            <value>true</value>  
        </property>  
    </bean>  
  
    <bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">  
        <property name="transactionTimeout" value="300" />  
    </bean>  
  
    <!-- spring 事务管理器 -->  
    <bean id="springTransactionManager"  
        class="org.springframework.transaction.jta.JtaTransactionManager">  
        <property name="transactionManager">  
            <ref bean="atomikosTransactionManager" />  
        </property>  
        <property name="userTransaction">  
            <ref bean="atomikosUserTransaction" />  
        </property>  
        <property name="allowCustomIsolationLevels" value="true">
        </property>
    </bean>  
    
    <!-- 事务拦截器 -->
	<bean id="transactionInterceptor"
		class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<!-- 配置事务管理器 -->
		<property name="transactionManager" ref="springTransactionManager" />
		<!-- 方法名：要求的事务属性 -->
		<property name="transactionAttributes">
			<props>
				<prop key="insertTest">PROPAGATION_REQUIRED,ISOLATION_REPEATABLE_READ,-Throwable
				</prop>
			</props>
		</property>
	</bean>
	
	<bean
		class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<list>
				<value>atomTransactionServiceImpl</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>
</beans>  

2.数据源:

datasource1:

package com.atom.jta.test;

import java.util.Properties;

import org.springframework.stereotype.Repository;

import com.atomikos.jdbc.AtomikosDataSourceBean;
@Repository
public class MasterAtomDatasource extends AtomikosDataSourceBean {
	
	private static final long serialVersionUID = -2471230875536339311L;

	public MasterAtomDatasource(){
		Properties prop = new Properties();
		prop.put("user", "root");
		prop.put("password", "");
		prop.put("URL", "jdbc:mysql://127.0.0.1:3306/test?autoReconnect=true");
		setXaDataSourceClassName("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");
		setUniqueResourceName("mysql_ds1");
		setPoolSize(5);
		setXaProperties(prop);
	}
	
}

 datasource2:

package com.atom.jta.test;

import java.util.Properties;

import org.springframework.stereotype.Repository;

import com.atomikos.jdbc.AtomikosDataSourceBean;
@Repository
public class SlaveAtomDataSource extends AtomikosDataSourceBean {

	private static final long serialVersionUID = -6210394799199416765L;
	public SlaveAtomDataSource(){
		Properties prop = new Properties();
		prop.put("user", "root");
		prop.put("password", "");
		prop.put("URL", "jdbc:mysql://127.0.0.1:3306/test1?autoReconnect=true");
		setXaDataSourceClassName("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");
		setUniqueResourceName("mysql_ds2");
		setPoolSize(5);
		setXaProperties(prop);
	}
	

}

3.BaseDao:

package com.atom.jta.test;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
@Repository
public class AtomBaseDao {
	private JdbcTemplate mastTemplate;
	private JdbcTemplate slaveTemplate;
	
	public JdbcTemplate getMastTemplate() {
		return mastTemplate;
	}
	@Resource(name="masterAtomDatasource")
	public void setMastTemplate(DataSource source) {
		this.mastTemplate = new JdbcTemplate(source);
	}
	public JdbcTemplate getSlaveTemplate() {
		return slaveTemplate;
	}
	@Resource(name="slaveAtomDataSource")
	public void setSlaveTemplate(DataSource source) {
		this.slaveTemplate = new JdbcTemplate(source);
	}
	
	
}

 4.测试service

package com.atom.jta.test;

import org.springframework.context.ApplicationContext;

public interface AtomTransactionService {
	public void insertTest(ApplicationContext ctx) throws Exception;
}

package com.atom.jta.test;

import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Service;
@Service
public class AtomTransactionServiceImpl implements AtomTransactionService {
	public void insertTest(ApplicationContext ctx) throws Exception {
		AtomBaseDao baseDao = ctx.getBean(AtomBaseDao.class);
		String str = "xxxx";
		String masterSql = "insert into demo (name) values "+"('"+str+"')";
		String slaveSql = "insert into test (name) values "+"('"+str+"')";
		baseDao.getMastTemplate().execute(masterSql);
		baseDao.getSlaveTemplate().execute(slaveSql);
		throw new Exception();
	}

}

 5.事务测试

package com.atom.jta.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AtomTest {
	public AtomTest(){
		ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-atomikos.xml");
		AtomTransactionService service = ctx.getBean(AtomTransactionService.class);
		try {
			service.insertTest(ctx);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public static void main(String[] args) {
		AtomTest test = new AtomTest();
		System.out.println("done.....");
	}

}

 就是如此简单
