Question

当我尝试运行Spring Boot 2.0.5应用程序且 entity 具有单边@ManyToOne关系时，

出于任何原因，控制台都会在日志下方显示在日志下方。如果 @ManyToOne已删除，控制台日志将清除，但应用程序加载正常且未显示任何错误。

在application.properties中设置DB，以在文件中创建（如果DB在内存中，则将得到相同的错误日志）。日志显示了正确的SQL，可以创建表，FK并插入新的预定义行（位于classpath：data.sql中）

我检查了不同的帖子，由于很多选择，似乎这个问题不容易解决。有什么建议么？谢谢。

不幸的是，

Update 并不是表名。我更新为USER_ACCOUNT，但遇到相同的错误：用户缺少特权或找不到对象：PUBLIC.USER_ACCOUNT。它必须与注释@ManyToOne相关，因为当我删除它时，一切都会很好地加载

Answer 1

您不能将“用户”用作表名，因为它是保留字。参见documentation

有两种解决方案。

1。将实体名称从“用户”更改为“用户”。

2。如果仍然要使用保留字，请使用反引号。

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'

mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

我建议您寻求第一种解决方案。

Spring Boot 2.0.5和HSQL文件数据库显示注销用户缺少特权或当实体包含@ManyToOne时找不到对象
