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

8. 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：

1.  在MySQL中设置  lower_case_table_names的值为'0'
2. 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

报错信息

1. org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

4. 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

1. @Entity
2. @Data
3. @Table(name = "T_BASE_ORDER_PRINT_CLIENT")
4. public class MerchantPrinter {
5.  
6. @Id
7. @Column(name = "print_client_id")
8. private String id;
9.  
10. @Column(name = "merchant_id")
11. private String merchantId;
12.  
13. private String imei;
14.  
15. }

最终的解决方案

1. 在spring jpa配置中增加physical-strategy配置解决问题
2.  
3. spring:
4. datasource:
5. driver- class-name: com.mysql.jdbc.Driver
6. url: jdbc:mysql: //XXX:3306/dbname
7. username: root
8. password: *******
9. schema:
10. jpa:
11. hibernate:
12. ddl-auto: none
13. naming:
14. physical-strategy: org .hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
15. show-sql: true

physical 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) 
physical naming strategy：物理命名策略，用于转换“逻辑名称”(隐式或显式)的表或列成一个物理名称
