SpringBoot全局异常拦截

SpringBoot全局异常捕获

使用到的技能

@RestControllerAdvice或(@ControllerAdvice+@ResponseBody)

@ExceptionHandler

代码实现

统一返回入口

自定义异常

全局异常处理

统一返回入口Result

/**

• @ClassName Result

• @Description 统一返回格式

• @Author chaoba

• @Version V1.0
  
  */
  
  @Data
  
  public class Result {
  
  private int code;
  
  private String msg;
  
  private T data;

  /**

  • 成功时候的调用
    
    */
    
    public static Result success(T data) {
    
    Result result = new Result(CodeMsg.SUCCESS);
    
    result.setData(data);
    
    return result;
    
    }

  /**

  • 成功时候的调用
    
    */
    
    public static Result successMsg(String msg) {
    
    return new Result(200, msg);
    
    }

  /**

  • 失败时候的调用
    
    */
    
    public static Result errorCodeMsg(CodeMsg codeMsg) {
    
    return new Result(codeMsg);
    
    }

  /**

  • 成功时候的调用
    
    */
    
    public static Result successCodeMsg(CodeMsg codeMsg) {
    
    return new Result(codeMsg);
    
    }

  public static Result error(T data) {
  
  Result result = new Result(CodeMsg.FAIL);
  
  result.setData(data);
  
  return result;
  
  }

  /**

  • 失败时候的调用
    
    */
    
    public static Result errorMsg(String msg) {
    
    return new Result(0, msg);
    
    }

  /**

  • 全部参数
  • @param
  • @param
  • @return
    
    */
    
    public static Result getResult() {
    
    return new Result();
    
    }

  public static Result toAjaxResult(int rows) {
  
  return rows > 0 ? success(null) : error(null);
  
  }

  public static Result toAjaxResult(boolean rows) {
  
  return rows ? success(null) : error(null);
  
  }

  private Result(T data) {
  
  this.data = data;
  
  }

  private Result() {
  
  }

  private Result(int code, String msg) {
  
  this.code = code;
  
  this.msg = msg;
  
  }

  private Result(CodeMsg codeMsg) {
  
  if (codeMsg != null) {
  
  this.code = codeMsg.getCode();
  
  this.msg = codeMsg.getMsg();
  
  }
  
  }

}

自定义异常

/**

• @ClassName GlabalException

• @Description 全局异常

• @Author chaoba

• @Version V1.0
  
  */
  
  @Data
  
  public class GlabalException extends RuntimeException {
  
  //错误状态码
  
  private int code;

  public GlabalException(int code) {
  
  this.code = code;
  
  }

  public GlabalException(String message, int code) {
  
  super(message);
  
  this.code = code;
  
  }

  public GlabalException(CodeMsg codeMsg) {
  
  super(codeMsg.getMsg());
  
  this.code = codeMsg.getCode();
  
  }

  public GlabalException(String message) {
  
  super(message);
  
  }

  public GlabalException(Throwable cause, int code) {
  
  super(cause);
  
  this.code = code;
  
  }

  public GlabalException(GlabalException ex) {
  
  super(ex);

  }
  
  }
  
  全局异常处理
  
  /**

• @ClassName GlabalExceptionHandler

• @Description 全局异常拦截，只提供接口-无需页面404等错误

• @Author chaoba

• @Version V1.0
  
  */
  
  @RestControllerAdvice
  
  public class GlabalExceptionHandler {
  
  //拦截自定义异常
  
  @ExceptionHandler(value = GlabalException.class)
  
  public Result jsonErrorHandler(GlabalException e) {
  
  Result

}
