报错：check the manual that corresponds to your MySQL server version for the right syntax

mysql数据库中建了order表，dao层OrderDAO继承了JpaRepository，想直接用其findAll()方法来取出order表的数据。结果一调用此方法控制台就报错：

2020-05-20 16:29:39.338  WARN 3964 --- [io-8888-exec-10] o.h.engine.jdbc.spi.SqlExceptionHelper   : SQL Error: 1064, SQLState: 42000

java实体类的字段和数据表的也一致。

最终看了check the manual that corresponds to your MySQL server version for the right syntax错误

说是表名order和mysql的关键字冲突了，这就是为什么报语法错误的原因。把表名order改为t_order就好了。
