为什么选择查询会在 JPA 休眠中触发乐观锁定错误？

编程问答 2022-05-28

问题描述

抛出了一个 ObjectOptimisticLockingFailureException。我检查了日志，发现这个异常是由一个选择查询触发的。这很奇怪。

这是异常堆栈跟踪。

日志显示它在更新 POS 表时遇到了乐观锁错误。这条线 "at net.homecredit.mcd.app.dao.UserRolePosDao.countOtherRoles(UserRolePosDao.java:225)"，触发此乐观错误。我检查了这段代码。

    public Integer countOtherRoles(User user,UserRolePos userRole) {
        return em.createNamedQuery(UserRolePos.COUNT_OTHER_ROLE_FOR_USER,Long.class)
                .setParameter("user",user)
                .setParameter("userRole",userRole)
                .getSingleResult().intValue();
    }

相关查询如下

 @NamedQuery(name = UserRolePos.COUNT_OTHER_ROLE_FOR_USER,query = "SELECT COUNT(urp) FROM UserRolePos urp " +
                "WHERE urp.user = :user " +
                "AND urp != :userRole "
        )

这只是对另一个 UserRole 表的选择查询，为什么会触发 POS 表的乐观锁错误？

解决方法

如果您仔细查看堆栈跟踪，您会注意到 Hibernate 会“自动刷新”。当您的持久性上下文中有“脏”实体并尝试使用与脏实体的表相交的表进行查询时，就会发生这种情况。如果它不刷新脏条目，您可能会得到错误的结果。
