一、問題

　　JPA中自動使用@Table(name = "userTab")後自動將表名、列名添加了下劃線的問題，如下圖：

二、解決

　　在application.properties文件中加入：

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

　　如：

#連接字符串
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url
 
=jdbc:mysql://172.16.4.203:3306/unicomcmpdb?characterEncoding=utf8&useUnicode=true&useSSL=false&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=123456
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
spring.datasource.platform
 
=org.hibernate.dialect.MySQL57Dialect
spring.jooq.sql-dialect=org.hibernate.dialect.MySQL57Dialect

#初始化數據
spring.datasource.schema=classpath:schema.sql
spring.datasource.data=classpath:data.sql
spring.datasource.sql-script-encoding=utf-8
spring.datasource.initialization-mode=ALWAYS
spring.datasource.continue-on-error
 
=true
#數據表命名下劃線問題
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

三、效果

JPA中自動使用@Table(name = "userTab")後自動將表名、列名添加了下劃線的問題
