使用JTA进行Hibernate会话处理（无法找到当前的JTA事务）

标签： java hibernate jboss wildfly jta

我使用Hibernate 4.3.7在Wildfly 8.2（JBoss）上运行java应用程序。我使用sessionFactory.openSession（）与数据库进行交互。我想使用JTA更改为每个请求的会话模式。我是这个领域的新手。

到目前为止我做了什么：

1 - 我将数据源配置从hibernate.cfg.xml移动到Wildfly配置

<datasources>
    <datasource jta="true" jndi-name="java:jboss/datasources/Dummy" pool-name="Dummy" enabled="true"
                use-ccm="true">
        <connection-url>jdbc:mysql://localhost/dummy</connection-url>
        <driver-class>com.mysql.jdbc.Driver</driver-class>
        <driver>dummy-1.0.war_com.mysql.jdbc.Driver_5_1</driver>
        <security>
            <user-name>root</user-name>
            <password>root</password>
        </security>
        <validation>
            <validate-on-match>false</validate-on-match>
            <background-validation>false</background-validation>
        </validation>
        <timeout>
            <set-tx-query-timeout>false</set-tx-query-timeout>
            <blocking-timeout-millis>0</blocking-timeout-millis>
            <idle-timeout-minutes>0</idle-timeout-minutes>
            <query-timeout>0</query-timeout>
            <use-try-lock>0</use-try-lock>
            <allocation-retry>0</allocation-retry>
            <allocation-retry-wait-millis>0</allocation-retry-wait-millis>
        </timeout>
        <statement>
            <share-prepared-statements>false</share-prepared-statements>
        </statement>
    </datasource>
    <drivers>
        <driver name="h2" module="com.h2database.h2">
            <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
        </driver>
    </drivers>
</datasources>

2 - 我将数据源，事务工厂，当前会话上下文类和JTA平台添加到hibernate.cfg.xml 

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.datasource">java:jboss/datasources/Dummy</property>

         <!--How to find the Transaction-->
        <property name="hibernate.transaction.factory_class">org.hibernate.engine.transaction.internal.jta.JtaTransactionFactory</property>

        <!-- How to produce transaction -->
        <property name="hibernate.transaction.jta.platform">org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform</property>

        <!-- Session context with JTA -->
        <property name="hibernate.current_session_context_class">jta</property>

    </session-factory>
</hibernate-configuration>

3 - 我将jbossjta添加到我的gradle依赖项中

compile group: 'org.jboss.jbossts', name: 'jbossjta', version: '4.16.6.Final'

4 - 我从openSession改为getCurrentSession（）

public class DatabaseManager {

    private static SessionFactory sessionFactory;

    private static SessionFactory getSessionFactory() {
        if (sessionFactory == null) {
            sessionFactory = createSessionFactory();
        }

        return sessionFactory;
    }

    public static Session createSession() {
        SessionFactory sessionFactory = DatabaseManager.getSessionFactory();

        // Session session = sessionFactory.openSession();
        Session session = sessionFactory.getCurrentSession();
        session.beginTransaction();

        return session;
    }

    public static void commitAndCloseSession(Session session) {
        session.getTransaction().commit();
        session.close();
    }

    private static SessionFactory createSessionFactory() {
        Configuration configuration = new Configuration()
                .configure("hibernate-entities.cfg.xml");

        StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
                .configure("hibernate-connection.cfg.xml")
                .build();

        return configuration.buildSessionFactory(registry);
    }

}

当应用程序调用getCurrentSession时，抛出以下异常：

我错过了什么？到目前为止我做了正确的事吗？
