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

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

jdbc2.username=root
jdbc2.password=leizhimin
iBatis的SQLMap配置：
sql-map-config_A.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

lazyLoadingEnabled="true" errorTracingEnabled="true"
useStatementNamespaces="true"/>
<sqlMap resource="com/lavasoft/stu/jtom/entity/sqlmap/TabB.xml"/>
</sqlMapConfig>
日志的配置：log4j.properties
log4j.rootLogger=INFO,CONSOLE,LOGFILE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out

log4j.logger.java.sql.Connection=debug
log4j.logger.java.sql.Statement=INFO,CONSOLE
log4j.logger.java.sql.PreparedStatement=INFO,CONSOLE
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.setName("aaa");
a.setAddress("address a");
TabB b = new TabB();
b.setId(1L);
b.setName("bbb");
b.setAddress("address b");
ser.saveAB(a, b);
}
public static void main(String[] args) {
test_();
}
}

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
jdbc.password=leizhimin

jdbc2.username=root
jdbc2.password=leizhimin
iBatis的SQLMap配置：
sql-map-config_A.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<settings cacheModelsEnabled="true" enhancementEnabled="true"

lazyLoadingEnabled="true" errorTracingEnabled="true"
useStatementNamespaces="true"/>
<sqlMap resource="com/lavasoft/stu/jtom/entity/sqlmap/TabB.xml"/>
</sqlMapConfig>
日志的配置：log4j.properties
log4j.rootLogger=INFO,CONSOLE,LOGFILE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out

log4j.logger.java.sql.Connection=debug
log4j.logger.java.sql.Statement=INFO,CONSOLE
log4j.logger.java.sql.PreparedStatement=INFO,CONSOLE
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.setName("aaa");
a.setAddress("address a");
TabB b = new TabB();
b.setId(1L);
b.setName("bbb");
b.setAddress("address b");
ser.saveAB(a, b);
}
public static void main(String[] args) {
test_();
}
}
