springboot 集成 jpa 详解

采用maven配置

项目结构：

添加相关依赖

        <!-- SpringData-Jpa依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <!-- mysql驱动:com.mysql.jdbc.Driver -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <dependency>

application.yml

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/test
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver
  jpa: 
    properties:
      hibernate: 
        hbm2ddl.auto: create-drop

UserRepository

public interface UserRepository extends JpaRepository<User,Integer> {

    @Query("From User")
    public List<User> findTest(); 

    public List<User> findByUsernameLike(String username);
}
