这个问题有2种解决方法：
我的报错是：
java.sql.SQLSyntaxErrorException: Table 'gaei_ms.gaei_work_task' doesn't exist方法一：

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'fecru.AO_B434B9_WEB_HOOK' doesn't exist原因：
MySQL对lower_case_table_names使用区分大小写的表名比较设置 （可能值为'0'）。但是，FishEye在表名 FE-4276中不一致-数据库表OPEN的大小写不一致。您可以使用以下查询确认设置：
show variables like 'lower_case_table_names'; 解决：
- 在MySQL中设置 lower_case_table_names的值为'0'
- 重新启动MySQL和FishEye / Crucible。
方法二：
我的情况是springboot项目，配置文件的改法略有不同：我的改法是在配置文件中加上这一行：
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl以下转自：https://blog.csdn.net/Halleycomett/article/details/78638639
报错信息
org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table XXX doesn't exist报错原因调查
mysql里实际表名都是大写
尝试在entity上标记表名大写，实际测试无效，仍然找不到表
@Entity
@Data
@Table(name = "T_BASE_ORDER_PRINT_CLIENT")
public class MerchantPrinter {@Id@Column(name = "print_client_id")private String id;@Column(name = "merchant_id")private String merchantId;private String imei;}最终的解决方案
在spring jpa配置中增加physical-strategy配置解决问题spring:datasource:driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://XXX:3306/dbnameusername: rootpassword: *******schema:jpa:hibernate:ddl-auto: nonenaming:physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImplshow-sql: truephysical naming strategy ：used to convert a “logical name” (either implicit or explicit) name of a table or column into a physical name (e.g. following corporate naming guidelines)
