基於 spring boot 對異常處理的不友好，現在通過其他的方式來統一處理異常

步驟一：自定義異常類

public class UserNotExistException extends RuntimeException{
    private static final long serialVersionUID = -1574716826948451793L;

    private String id;

    public UserNotExistException(String id){
        super("user not exist");
        
 
this.id = id;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

步驟二：定義異常處理類

@ControllerAdvice
public class ControllerExceptionHandler {

    @ExceptionHandler(UserNotExistException.class)
    @ResponseBody
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    
 
public Map<String, Object> handleUserNotExistsException(UserNotExistException e) {
        Map<String, Object> map = new HashMap<>();
        map.put("id", e.getId());
        map.put("message", e.getMessage());
        return map;
    }
}

步驟三：控制層拋出異常

  @GetMapping("/{id:\\d+}
 
")
    public void get(@PathVariable String id) {
        throw new UserNotExistException(id);
   }

spring boot 中統一異常處理
