net user User ****** /add

@RequestMapping("/front/login") @RestController public class FrLoginController { @Resource FrLoginService frLoginService; /** * 注册用户 */ @PostMapping("/addOne") public Result addOne(UserPO user){ return Result.success(frLoginService.addOne(user)); } /** * 用户登录 */ @GetMapping("/showOne") public Result showOne(String uAccount,String uPassword){ return Result.success(frLoginService.showOne(uAccount,uPassword)); } /** * 查重用户名 */ @GetMapping("/showByUAccount") public Result showByUAccount(String uAccount){ return Result.success(frLoginService.showByUAccount(uAccount)); } }

该方法接收一个UserPO对象作为参数，调用frLoginService.addOne(user)方法来注册用户，并将结果通过Result.success()方法返回。在showOne方法中，使用@GetMapping注解将该方法映射到"/front/login/...

@RestController @RequestMapping("users") public class Usercontroller { @Autowired private UserService userService; @GetMapping() public List<User> getUserList(){ return userService.getUserList(); } /根据id查询/ @GetMapping("{id}") public User getUserList(@PathVariable int id){ return userService.getUserById(id); } /新增/ @GetMapping() public Void add(User user) { userService.add(user); return null; } /更新/ @PutMapping() public User update(User user){ userService.update(user); return user; } /删除/ @DeleteMapping("{id}") public void delete(@PathVariable int id){ userService.delete(id); }

3. add(User user) 方法使用 @GetMapping 注解，处理了 "/users" 路径的 GET 请求，用于新增用户。它接收一个 User 对象作为参数，并调用 UserService 的 add(user) 方法来进行用户添加。 4. update(User ...

这段代码是关于断言的一段代码。断言是一种调试技术，可以在程序中加入一些检查，用来检测程序运行时的错误。当程序执行到断言语句时，如果断言条件为假，则程序会停止运行并报告错误。在这段代码中，使用了宏定义...

这是用于初始化GPIO引脚的函数。在该函数中，首先使能了GPIOC、GPIOD和GPIOB端口的时钟。然后，配置了LEDR_OUT_PD3_Pin引脚为输出模式，初始电平为高电平。接着，配置了RS485_RE_OUT_PB8_Pin和RS485_SE_OUT_PB9_Pin...
