第三课主要是健康管理员端后台接口开发，主要功能有健康管理员对基本信息（姓名、性别、年龄、手机）的操作、用户和健康管理员转账的功能。

AccountController.java

// 标记controller，返回json数据
@RestController
public class AccountController {

    // 自动注入service
    @Autowired
    private AccountService accountService;

    /**
     * 转账
     * @param transferDetail
     * @return
     */
    @PostMapping("transfer")
    public ResultObject add(@RequestBody TransferDetail transferDetail) {
        String status = accountService.transfer(transferDetail);
        ResultObject resultObject = new ResultObject(200, status, null);
        return resultObject;
    }
}

DoctorController.java

// 标记controller，返回json数据，URL前缀：/doctor
@RestController
@RequestMapping("doctor")
public class DoctorController {

    // 自动注入service
    @Autowired
    private DoctorService doctorService;

    /**
     * 创建健康管理员
     * @param doctor
     * @return
     */
    @PostMapping("add")
