一、问题
JPA中自动使用@Table(name = "userTab")后自动将表名、列名添加了下划线的问题，如下图：
二、解决
在application.properties文件中加入：
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
如：
#连接字符串
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 #初始化数据
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
#数据表命名下划线问题
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
