JTA事物管理

Spring+iBatis+Atomikos实现JTA事务

 

Atomikos是一个公司名字，旗下最著名的莫过于其Atomikos的事务管理器产品。

 

产品分两个：一个是开源的TransactionEssentials，一个是商业的ExtremeTransactions。

 

TransactionEssentials的主要特征：

JTA/XA 事务管理 —— 提供事务管理和连接池

不需要应用服务器 —— TransactionEssentials可以在任何Java EE应用服务器中运行，也就是不依赖于任何应用服务器

开源 —— TransactionEssentials是遵守Apache版本2许可的开源软件

专注于JDBC/JMS —— 支持所有XA资源，但是资源池和消息监听是专供JDBC和JMS的

与Spring 和 Hibernate 集成 —— 提供了描述如何与Spring和Hibernate集成的文档

 

ExtremeTransactions 是基于TransactionEssentials之上的，增加了对非XA事务的支持，在servlet容器中提供了图形化管理控制面板。Atomikos还提供了基于订阅的支持服务，一份订阅可以得到访问ExtremeTransactions中额外功能的权限。

Pardon继续说道，在很多情况下，一个应用服务器对于一个应用也许不是最佳方案 —— 他以SOA/ESB终端作为例子，阐述了通过JDBC来处理JMS消息可能是一个非常轻量级的可伸缩的方案。

 

 

关于TransactionEssentials的后继版本，Pardon提到了更强大的JDBC和JMS连接池，支持OSGi 和JMX事务管理工具，是计划中的3.3版的主要特征。Pardon还说明为JDBC数据源和JMS连接器增加JMX是4.0版的目标。

 

 

 

下面是Spring+iBatis+Atomikos实现JTA事务的测试过程：

 

一、环境

 

1、准备软件环境

 

 spring-framework-2.5.6.SEC01-with-dependencies.zip
 ibatis-2.3.4
 AtomikosTransactionsEssentials-3.5.5.zip
 MySQL-5.1
 JDK1.5
 
 http://www.atomikos.com/downloads/transactions-essentials/3.5.5/AtomikosTransactionsEssentials-3.5.5.zip

 

2、创建数据库环境，注意数据库引擎为InnoDB，只有这样才能支持事务。

 

CREATE DATABASE IF NOT EXISTS testdb_a        DEFAULT CHARACTER SET utf8;    

USE testdb_a;    

DROP TABLE IF EXISTS tab_a;    

CREATE TABLE tab_a (    
        id bigint(20) NOT NULL,    
        name varchar(60) DEFAULT NULL,    
        address varchar(120) DEFAULT NULL,    
        PRIMARY KEY (id)    
) ENGINE=InnoDB DEFAULT CHARSET=utf8;    


CREATE DATABASE IF NOT EXISTS testdb_b        DEFAULT CHARACTER SET utf8;    

USE testdb_b;    

DROP TABLE IF EXISTS tab_b;    

CREATE TABLE tab_b (    
        id bigint(20) NOT NULL,    
        name varchar(60) DEFAULT NULL,    
        address varchar(120) DEFAULT NULL,    
        PRIMARY KEY (id)    
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

三、配置

 

jta.properties

com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory
com.atomikos.icatch.console_file_name = tm.out
com.atomikos.icatch.log_base_name = tmlog
com.atomikos.icatch.tm_unique_name = com.atomikos.spring.jdbc.tm
com.atomikos.icatch.console_log_level = INFO
