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-context.jar
│    spring-core.jar
│    spring-jdbc.jar
│    spring-jms.jar
│    spring-orm.jar
│    spring-test.jar
│    spring-tx.jar
│    spring-web.jar
│    spring-webmvc-portlet.jar
│    spring-webmvc-struts.jar
│    spring-webmvc.jar
│    aspectjrt.jar
│    aspectjweaver.jar
│    cglib-nodep-2.1_3.jar
│    asm-2.2.3.jar
│    log4j-1.2.15.jar
│    asm-commons-2.2.3.jar
│    asm-util-2.2.3.jar
│    aopalliance.jar
│    mysql-connector-java-5.1.6-bin.jar
│
├─ibatis
│            ibatis-2.3.4.726.jar
│            sql-map-2.dtd

│

│            xapool.jar
│            jotm-core.jar
│            jotm-standalone.jar
│            jotm-jms.jar
│            jotm-datasource.jar
│            ow2-jta-1.1-spec.jar
│            jotm-client.jar
│

│            commons-attributes-api.jar
│            commons-attributes-compiler.jar

│            commons-io.jar
│            commons-lang.jar
│            commons-logging.jar
│            commons-pool.jar
│            commons-validator.jar
│
├─junit
│            junit-3.8.2.jar
│            junit-4.4.jar
│            license.txt
│
└─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" >

<!-- 表名:tab_a -->
< sqlMap namespace ="tab_a" >
        < typeAlias alias ="TabA" type ="com.lavasoft.stu.jtom.entity.TabA" />
        < resultMap id ="result_base" class ="TabA" >
                < result property ="id" column ="id" />
                < result property ="name" column ="name" />
                < result property ="address" column ="address" />
        </ resultMap >
        <!-- 添加 -->
        < insert id ="insert" parameterClass ="TabA" >
                insert into tab_a(
                id,
                name,
                address
                ) values (

                #name#,
                #address#
                )
                < selectKey keyProperty ="id" resultClass ="long" >
                        select LAST_INSERT_ID()
                </ selectKey >
        </ insert >
        <!-- 更新 -->

                where id = #id#
        </ update >
        <!-- 删除 -->
        < delete id ="deleteById" parameterClass ="long" >
                delete from tab_a
                where id = #value#
        </ delete >
        <!-- 根据ID获取 -->
        < select id ="findById" parameterClass ="long" resultMap ="tab_a.result_base" >
                select *
                from tab_a
                where id = #value#
        </ select >
</ sqlMap >

 

TabB.xml

<? xml version ="1.0" encoding ="UTF-8" ?>

        </ resultMap >
        <!-- 添加 -->
        < insert id ="insert" parameterClass ="TabB" >
                insert into tab_b(
                id,
                name,
                address
                ) values (

                #address#
                )
                < selectKey keyProperty ="id" resultClass ="long" >

                id = #id#,
                name = #name#,

                where id = #id#
        </ update >
        <!-- 删除 -->
        < delete id ="deleteById" parameterClass ="long" >

        <!-- 根据ID获取 -->
        < select id ="findById" parameterClass ="long" resultMap ="tab_b.result_base" >
                select *
                from tab_b
                where id = #value#
        </ select >
</ sqlMap >

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.database=cms_release
jdbc2.driver=com.mysql.jdbc.Driver
jdbc2.url=jdbc:mysql://192.168.0.1:3306/testdb_b?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull
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/TabA.xml" />

</ sqlMapConfig >

 

sql-map-config_B.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.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss } - %-5p %c        %x - %m%n

log4j.appender.LOGFILE=org.apache.log4j.RollingFileAppender
log4j.appender.LOGFILE.File=contestlog.log
log4j.appender.LOGFILE.MaxFileSize=500KB
log4j.appender.LOGFILE.MaxBackupIndex=10
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss } -    %-p %c     %x - %m%n

log4j.logger.com.ibatis=INFO
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=INFO
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=INFO
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=INFO
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_();
        }
}

 

然后将主键其中一个改掉进行测试，让另外一个主键重复，发现a、b数据库均不能成功写入，经过多次测试，验证jtom真正实现了分布式事务的管理。
