将weblogic迁移到tomcat:没有可用的JTA UserTransaction

时间:2018-08-29 08:25:33

标签: java spring hibernate tomcat jta

我正在处理多模块Maven应用程序,并且Weblogic已经投入生产。堆栈是:

Tomcat 8.5

PostGre 9.6

休眠4.3.8

春季4.1.5

Spring Security 3.2.6

Spring Struts 3.2.13

Prime Faces 5.1

我开始通过在server.xml中创建JNDI数据源和在META-INF / context.xml中创建资源链接(我们将数据库从DB2移至PostGre)进行迁移,但是我遇到了一个例外:

由以下原因引起:java.lang.IllegalStateException:没有可用的JTA UserTransaction -指定“ userTransaction”或“ userTransactionName”或“ transactionManager”或“ transactionManagerName”

我的应用程序位于xml config上,并且我认为错误发生是因为JTA权限已委派给旧版本的weblogic:

DataSourceContext.xml

我的Tomcat数据源:

     UserDatabaseRealm to authenticate users

    <Resource auth="Container" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" name="UserDatabase" pathname="conf/tomcat-users.xml" readonly="true" type="org.apache.catalina.UserDatabase"/>

我认为我必须在DataSourceContext.xml中替换此道具: org.hibernate.engine.transaction.jta.platform.internal.WeblogicJtaPlatform吗?

现有的干净解决方案可以在tomcat 8.5中实现事务管理器吗?还是独立的事务管理器?

对于已经找到的所有解决方案(旧版本的JTA休眠或折旧的JTA),我感到困惑...如果有人可以启发我,我将不胜感激:)

答案 0 :(得分:0)

虽然Weblogic是完整的Application Server,但是Tomcat仅是Web容器。因此,您需要缩小两者之间的一些距离。

交易经理就是其中之一。 Weblogic将“自动”为您添加一个,而Tomcat无法这样做。

如果使用下面的代码片段,则应该可以克服此问题。

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
