springboot集成hibernate-jpa方式

1、maven依赖

   org.springframework.boot
   spring-boot-starter-data-jpa


   mysql
   mysql-connector-java

2、application.yml

# Hibernate JPA
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db_demo
    username: root
    password: root
    driverClassName: com.mysql.jdbc.Driver
  jpa:
    database: MYSQL
    hibernate:
      ddl-auto: update
      dialect: org.hibernate.dialect.MySQL5Dialect
    show-sql: true

3、jpa配置

@Configuration
@EntityScan(basePackages="com.glodon.springboot.po")
@EnableJpaRepositories(basePackages= "com.glodon.springboot.repository")
@EnableTransactionManagement
public class HibernateJpaConfig {

}

4、测试demo
