首先上官方参考文档

https://docs.spring.io/spring-data/rest/docs/current/reference/html/#reference
https://github.com/spring-projects/spring-hateoas-examples/tree/master/spring-hateoas-and-spring-data-rest
spring的文档还是写的很不错的

第一步引入pom

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-hateoas</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-rest</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <!-- http://127.0.0.1:8080/api/browser/index.html 来查看api 记住加上baseurl/-->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-rest-hal-browser</artifactId>
        </dependency>

设置

设置basepath

spring.data.rest.base-path=/api

这里要注意的是spring-data-rest-hal-browser使用这个api可视化查看文档，如果加了base-path 查看的时候一定要加上这个

数据库设置

spring.datasource.username=**
spring.datasource.password=**
spring.datasource.driver-class-name =com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/ethan?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

编写实体类和数据库层

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
@Entity
@JsonIgnoreProperties(value = { "hibernateLazyInitializer"})
public class User implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String userName;
    private String passWord;
}
@RepositoryRestResource(path = "user")
public interface UserRepository extends JpaRepository<User,Long> {

    @Query(value = "select * from  user where user_name=?1",nativeQuery = true)
    List<User>findByName(@Param("name") String name);

}

写完这些就大功告成了，记住不要写services和controller层了，现在直接可以增删改查了，增加接口就只需要在dao层直接写方法就行了，是不是很香~~~

最终效果

browser接口查询页面

默认的接口

这里只列举了查询，新增，更新，和删除可以自己尝试！

自定义的查询接口findByName
