Question

我无法构建我的实体管理器工厂，我得到的错误是“选择的事务策略需要访问JTA事务管理器”。任何人都可以建议我必须配置什么来通过这个？仅供我使用Jboss 6，没有弹簧。

这是我的 persistance.xml

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="AvengersPU" transaction-type="JTA">
    <jta-data-source>java:/jdbc/thor_ds</jta-data-source>
    <class>avenger.Grouptable</class>
    <class>avenger.MyUser</class>
    <exclude-unlisted-classes>true</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
    </properties>
  </persistence-unit>
</persistence>

这是部分堆栈跟踪...

Answer 1

这是一个非理想的答案，我将在此同时使用。

指定非jta数据源：

<non-jta-data-source>java:/jdbc/thor_ds</non-jta-data-source>

将交易类型从JTA更改为RESOURCE_LOCAL

<persistence-unit name="AvengersPU" transaction-type="RESOURCE_LOCAL">

这是关于主题的discussion：
