Question

在将Hibernate4更新为Hibernate5之后，我提出了这个问题：休眠必需的事务，尽管这是一个静态方法，不应有任何事务...

javax.persistence.TransactionRequiredException：执行更新/删除查询 org.hibernate.query.internal.AbstractProducedQuery.executeUpdate（AbstractProducedQuery.java:1586）〜[hibernate-core-5.3.6.Final.jar：5.3.6.Final]在 com.security.sa.core.dao.impl.BaseDaoImpl $ 10.doInHibernate（BaseDaoImpl.java:565）〜[sa-ui-util-3.8.1.0.jar :?]在 org.springframework.orm.hibernate5.HibernateTemplate.doExecute（HibernateTemplate.java:384）〜[spring-orm-5.1.5.RELEASE.jar：5.1.5.RELEASE]在 org.springframework.orm.hibernate5.HibernateTemplate.execute（HibernateTemplate.java:336）〜[spring-orm-5.1.5.RELEASE.jar：5.1.5.RELEASE]在 com.security.sa.core.dao.impl.BaseDaoImpl.execSQLUpdate（BaseDaoImpl.java:555）在 com.security.sa.rps.core.rpt.common.DynamicDao.execSQLUpdate（DynamicDao.java:84）〜[sa-ui-business-3.8.1.0.jar :?]在 com.security.sa.rps.core.rpt.common.rptserver.SearchTask.resetTasks（SearchTask.java:176）〜[sa-ui-business-3.8.1.0.jar :?]在 com.security.sa.rps.core.rpt.common.rptserver.ServerInitializer $ 2.run（ReportServerInitializer.java:78） [sa-ui-business-3.8.1.0.jar：？]

在Thread中调用静态方法，我认为@Transactional对静态方法无效

// while hibernate5 still throw TransactionRequiredException
new BasicThread("doRestartServerTask") {
        @Override
        public void run() {
            while (isRun() && !isInited) {
                try {
                    // TransactionRequiredException caused by calling this static method
                    SearchTask.resetTasks();
                } catch (Throwable e) {
                    LOGGER.error(e.getMessage(), e);
                }
                threadSleep(3 * 1000);
            }
        }
    }.start();

@Transactional  //always got problem  no matter adding this @Transactional or not
public static void resetTasks() {
    DynamicDao rptdao = BasicOps.getReportDbDao();
    ......
    rptdao.execSQLUpdate(Sql)
}

public int execSQLUpdate(final String sql, final Object... params) {
    Integer cnt = ((Integer) this.getHibernateTemplate().execute(new HibernateCallback<Object>() {
        public Object doInHibernate(Session session) throws HibernateException {
            SQLQuery query = session.createSQLQuery(sql);
            ......
            return query.executeUpdate();
        }
}

TransactionRequiredException：对静态方法执行更新/删除查询
