jpa 查詢 帶下划線

添加jpa策略

spring:
    jpa:
       hibernate:
          naming:
            physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
       database: mysql

 

兩種策略的含義：

//1.PhysicalNamingStrategyStandardImpl：不做修改，直接映射
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
 
//2.SpringPhysicalNamingStrategy:在進行領域映射時,首字母小寫，大寫字母變為下划線加小寫
//ex: LoginName --> login_name
spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
