Spring.x+Hibernate__java

 二、Spring.x+Hibernate+Atomikos整合

    Spring.x+Hibernate怎麼整合此處省略不說，主要講解Spring.x+Atomikos的整合，操作步驟如下：

    1、Atomikos,需要以下這些包

    atomikos-util-1.0.jar

    cglib-nodep-2.2.2.jar

    transactions-3.7.0.jar

    transactions-api-3.7.0.jar

    transactions-jdbc-3.7.0.jar

    transactions-jta-3.7.0.jar

    2、配置

    在applicationContext.xml檔案當中作如下配置

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

    <beans xmlns="http://www.springframework.org/schema/beans"

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