Springboot 集成JPA 完成接口demo

从事一段时间Android的我，通常都是调用别人的接口来进行相关的开发，但是一直以来对于接口问题和后端开发的同学争吵不休，无法确定责任到底在谁，最终在这种情况下，我重新回到自己之前的Java开发，经过了两个小时的努力，完成了一个以springboot 为框架，其中集成了jpa，mysql的方式来完成。废话不多说了，直接上代码！
其中项目的依赖文件为 ：

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

            org.springframework.boot        spring-boot-starter-web                org.springframework.boot        spring-boot-devtools        runtime        true                mysql        mysql-connector-java        runtime                org.springframework.boot        spring-boot-starter-test        test                ，            application.properties  的配置文件为：

spring.datasource.url=jdbc:mysql://localhost:3306/zhiteng?characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#配置JPA
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

bean 文件为：

@Entity
public class User {@Column
br/>@Column

br/>@GeneratedValue()

br/>@Column

br/>@Column

br/>@Column

br/>@Column

br/>@Column

br/>@Column

br/>@Column

br/>@Email

public String Email;@Column
br/>@Column

br/>@Column

br/>@Column

br/>@Column

br/>@Column

}
JPA ：

public interface UserJpa extends JpaRepository {
long countUserByPhoneNum(String phoneNum);
}

Controller：@RestController
br/>@RestController

br/>@Autowired

@RequestMapping(value = register)public Result register(@RequestParam("userName") String userName, @RequestParam("password") String password, String address, int age, String name,                       String userAccount, String Email, @RequestParam("userPhone") String userPhone, String nikeName) {    Result result = new Result();    long tag = userJpa.countUserByPhoneNum(userPhone);    if (tag > 0) {        result.code = 201;        result.msg = "用户已存在，可以直接登录";    } else {        User user = new User();        user.userID = SerialUtils.getUserId();        user.name = name;        if (StringUtils.isEmpty(userAccount)) {            user.userAccount = userName;        } else {            user.userAccount = userAccount;        }        user.phoneNum = userPhone;        user.password = MyMD5Util.getMD5(password);        if (StringUtils.isEmpty(nikeName)) {            user.nikeName = "zhiteng" + userPhone.substring(userPhone.length() - 4);        } else {            user.nikeName = nikeName;        }        user.userName = userName;        if (StringUtils.isEmpty(address)) {            user.address = "陕西，渭南";        } else {            user.address = address;        }        user.age = age;        user.Email = Email;        user.userType = UserType.common;        user.userRule = UserRule.user;        User u = userJpa.save(user);        if (null == u) {            result.code = 202;            result.data = user;            result.msg = "注册失败";        } else {            result.code = 200;            result.data = user;            result.msg = "注册成功";        }    }    return result;}

}

对于Controller中的各类注解解释如下：@RestController将返回数据自动格式化为json文件
br/>@RestController将返回数据自动格式化为json文件

@RequestParam 必传参数，
其他为非必传参数
