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代码  
<?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"

    default-lazy-init="true">

        <property name="allowCustomIsolationLevels" value="true">

    <!-- 事务拦截器 -->

        <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

            <list>  
                <value>transactionInterceptor</value>  
            </list>  
        </property>  
    </bean>  
</beans>    

2.数据源:

datasource1:

Java代码  
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:

Java代码  
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:

Java代码  
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

Java代码  
package com.atom.jta.test;  
  
import org.springframework.context.ApplicationContext;  
  
public interface AtomTransactionService {  
    public void insertTest(ApplicationContext ctx) throws Exception;  
}  

Java代码  
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

Java代码  
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.....");  
    }  
  
}
