工作总结（鄂州商城数据库配置）————spring配置多数据源+atomikos分布式事务

本文主要是介绍工作总结（鄂州商城数据库配置）————spring配置多数据源+atomikos分布式事务，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

宜宾商城用的是druid数据库，鄂州商城用的是多数据源。于是想总结这块的数据库配置。先看鄂州的。

---------------------背景-------------

鄂州商城有一部分信息，是深圳项目组做的后台系统发布的数据，我需要展示在门户网站上，可以让同事写接口提供。但是我直接配数据库直接读取了（多数据源）。

其实简单配个多数据源我这就够用了，因为本身没有分布式事务的业务。之前的招标采购系统有报建，历史，正式多个库，且业务上多库间需要维护事务，那里才用的合适。当然鄂州这里我们还是实现分布式事务。

---------大致讲下鄂州的数据库配置------

1.依赖包 pom.xml 中

<!-- Atomikos dependencies -->
<dependency>
   <groupId>com.atomikos</groupId>
   <artifactId>transactions</artifactId>
   <version>3.9.3</version>
</dependency>
<dependency>
   <groupId>com.atomikos</groupId>
   <artifactId>transactions-jta</artifactId>
   <version>3.9.3</version>
</dependency>
<dependency>
   <groupId>com.atomikos</groupId>
   <artifactId>transactions-jdbc</artifactId>
   <version>3.9.3</version>
</dependency>

2.配置数据源

<!-- 交易网的数据库 -->
<bean id="dataSourceJyw" class="com.atomikos.jdbc.AtomikosDataSourceBean">
   <property name="uniqueResourceName" value="dataSourceJyw"/>
   <property name="xaDataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"/>
   <property name="xaProperties">
      <props>
         <prop key="user">${userjyw}</prop>       
         <prop key="password">${passwordjyw}</prop>       
         <prop key="URL">${urljyw}</prop>   
         <prop key="pinGlobalTxToPhysicalConnection">true</prop>       
      </props>
   </property>
   <property name="minPoolSize" value="2"/>
   <property name="maxPoolSize" value="${cpool.maxPoolSize}"/>
   <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>
   <property name="testQuery" value="select 1 "/>
</bean>

3.使用数据源 ,配置sessionfactory

<bean id="sessionFactoryJyw" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
   <property name="dataSource" ref="dataSourceJyw" />
   <property name="jtaTransactionManager" ref="atomikosTransactionManager" /> 
   <property name="hibernateProperties">
      <value>
      hibernate.dialect=org.hibernate.dialect.MySQLDialecthibernate.show_sql=truehibernate.format_sql=truehibernate.query.substitutions=true 1, false 0hibernate.jdbc.batch_size=20hibernate.current_session_context_class=jtahibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory<!-- hibernate.connection.release_mode=after_statement -->
      </value>
   </property>
   <property name="packagesToScan">
      <list>  
         <value>com.truelore.jyw.*</value>  
      </list>  
   </property>  
</bean>

4.配置事务

<!-- 配置事务 -->
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
   <property name="forceShutdown" value="true"/>
   <!-- <property name="startupTransactionService" value="true" />
       <property name="transactionTimeout" value="300" /> -->
</bean>

<!-- Atomikos事务实现 -->
<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
   <property name="transactionTimeout" value="300"/>
</bean>

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
   <property name="transactionManager" ref="atomikosTransactionManager"/>
   <property name="userTransaction" ref="atomikosUserTransaction"/>
   <!-- <property name="allowCustomIsolationLevels" value="true"/> -->
</bean>

<tx:annotation-driven transaction-manager="transactionManager" order="1" />

5.atomikos的配置文件jta.properties
