4.JotmFactoryBean實現類

import javax.naming.NamingException;


import org.objectweb.jotm.Current;
import org.objectweb.jotm.Jotm;
import org.omg.CORBA.SystemException;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.beans.factory.FactoryBean;

public class JotmFactoryBean implements FactoryBean, DisposableBean {

    private Current jotmCurrent;
    private Jotm jotm;

    public JotmFactoryBean() throws NamingException {
        jotmCurrent = Current.getCurrent();
        if (jotmCurrent == null) {
            jotm = new Jotm(true, false);
            jotmCurrent = Current.getCurrent();
        }
    }

    public void setDefaultTimeout(int defaultTimeout) {
        jotmCurrent.setDefaultTimeout(defaultTimeout);
        try {
            try {
                jotmCurrent.setTransactionTimeout(defaultTimeout);
            } catch (javax.transaction.SystemException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } catch (SystemException ex) {
        }
    }

    public Jotm getJotm() {
        return jotm;
    }

    public Object getObject() {
        return jotmCurrent;
    }

    public Class<? extends Current> getObjectType() {
        return jotmCurrent.getClass();
    }

    public boolean isSingleton() {
        return true;
    }

    public void destroy() {
        if (jotm != null)
            jotm.stop();
    }

}

5.springMVC-servlet.xml配置

<beans xmlns="http://www.springframework.org/schema/beans"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"  
        xmlns:context="http://www.springframework.org/schema/context"

            http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd   
            http://www.springframework.org/schema/context   
            http://www.springframework.org/schema/context/spring-context-3.2.xsd   
            http://www.springframework.org/schema/aop   
            http://www.springframework.org/schema/aop/spring-aop-3.2.xsd   
            http://www.springframework.org/schema/tx   
            http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">  

        <!-- 配置Handler，handler實現了Controller接口 -->  
        <!-- 啓用spring mvc 註解 -->
        <context:annotation-config />
       <!-- 對於註解的Handler(Controller)可以單個配置實際開發中建議使用組件掃描  -->
       <context:component-scan base-package="com.xy.controller"></context:component-scan>
         <!-- 視圖解析器這裏配置前綴爲jsp,vm所在的路徑，後綴配置爲jsp,vm,所以在Controller中返回的時候只需要進行返回文件的名稱就可以了，視             圖解析器會找到該名稱的文件進行渲染  -->  
    <bean  
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <!-- 配置jsp路徑的前綴 -->  
        <property name="prefix" value="/WEB-INF/jsp/"/>  
        <!-- 配置jsp路徑的後綴 -->  
        <property name="suffix" value=".jsp"/>  
    </bean> 
 </beans>

2.JOTM簡介

1.JOTM是個開源的JTA事務管理組件，可以讓程序脫離J2EE容器而獲得分佈式事務管理的能力
2.spring集成JOTM編程步驟:
A.定義JotmFactoryBean實現類
B.實例org.springframework.transaction.jta.JtaTransactionManager—JTA事物管理器,注入JOTM實例
C.配置JOTM對應的數據源org.enhydra.jdbc.pool.StandardXAPoolDataSource
