Spring_ibatis_jta多数据源配置

Spring+iBatis+JOTM实现JTA事务
JOTM是个开源的JTA事务管理组件，可以让程序脱离J2EE容器而获得分布式事务管理的能力。
测试过程如下：
一、环境
1、准备软件环境
spring-framework-2.5.6.SEC01-with-dependencies.zip
ibatis-2.3.4
ow2-jotm-dist-2.1.4-bin.tar.gz
MySQL-5.1
JDK1.5
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;
二、建立项目testJOTM
1、建立项目后，准备依赖的类库，结构如下：
│ spring-aop.jar
│ spring-beans.jar
│ spring-context-support.jar

│ spring-jms.jar
│ spring-orm.jar

│ asm-2.2.3.jar
│ log4j-1.2.15.jar
│ asm-commons-2.2.3.jar
│ asm-util-2.2.3.jar

│
├─ibatis
│ ibatis-2.3.4.726.jar

│
└─log4j
log4j-1.2.15.jar
2、根据表建立entity和SQLMap
public class TabA implements Serializable {
private Long id;
private String name;
private String address;
//省略getter/setter
public class TabB implements Serializable {
private Long id;
private String name;
private String address;
//省略getter/setter
TabA.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" >
<sqlMap namespace="tab_a">

</insert>

<select id="findById" parameterClass="long" resultMap="tab_a.result_base">

</sqlMap>
TabB.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" >

</resultMap>
<insert id="insert" parameterClass="TabB">

</select>
</sqlMap>

B的DAO和A类似，就不写了。

三、做JTOM、Spring、iBatis、Log4j等配置
JOTM配置：carol.properties
#JNDI调用协议
carol.protocols=jrmp
#不使用CAROL JNDI封装器
carol.start.jndi=false
#不启动命名服务器
carol.start.ns=false
Spring配置：ApplicationContext.xml

数据库配置：jdbc.properties
jdbc.database=cms_release
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.0.2:3306/testdb_a?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull
jdbc.username=root

四、测试
public class Test {
private static ApplicationContext ctx = ApplicationContextUtil.getApplicationContext();
private static StuJotmService ser = (StuJotmService) ctx.getBean("stuJotmService");
public static void test_() {
TabA a = new TabA();
a.setId(1L);

a.setAddress("address a");
TabB b = new TabB();

b.setName("bbb");
b.setAddress("address b");
ser.saveAB(a, b);
}
public static void main(String[] args) {
