Hibernate错误消息：意外令牌：NULLS（脚本文件行中的错误：13个意外令牌：NULLS）

标签： hibernate java-ee null mapping hsqldb

在学习Hibernate时，我遇到了一个非常模糊的错误消息。首先是一些快速的背景。我以前有一个表数据库工作正常。现在我添加了第二个表，第一个表包含第二个表的集合。更清楚地说，我之前有一个Team表。现在我添加了一个Player表。团队包含一个属性，用于保存该团队的团队成员。当然团队成员是由球员组成的。我想让这个工作，但我不明白错误信息。我已经包含了我认为相关的文件。我省略了我的家庭控制器和团队控制器以及相关的视图，因为这些从未触及过上一个工作版本。还省略了DAO和Service层;再也没有碰过。这是错误日志：

答案 0 :(得分：3)

问题出在database.script文件中。添加播放器表时，以下行添加到脚本中（这必须是自动的，因为我没有触及此文件）：

SET DATABASE SQL NULLS FIRST TRUE
SET DATABASE SQL AVG SCALE 0

然后我不得不改变这一行：

database.script的更改

SET DATABASE TRANSACTION ROLLBACK ON CONFLICT TRUE

到

SET DATABASE TRANSACTION ROLLBACK ON DEADLOCK TRUE

任何人都能解释为什么会这样吗？ HSQL不喜欢令牌NULL或AVG？无论如何，那都在堆栈跟踪中。

答案 1 :(得分：2)

您必须在db.script文件中更改此行：

SET DATABASE TRANSACTION ROLLBACK ON CONFLICT TRUE

到

SET DATABASE TRANSACTION ROLLBACK ON DEADLOCK TRUE

再次打开后，db.script删除新生成的行

SET DATABASE SQL AVG SCALE 0

这将使其发挥作用。
