【Spring】SpringBoot 全局異常捕獲和處理

一、編寫全局異常捕獲的類

@ControllerAdvice
public class BaseExceptionHandler {

    @ExceptionHandler(value = Exception.class)
    @ResponseBody
    public Result error(Exception e) {
        e.printStackTrace();
        return new Result(false, StatusCode.ERROR, e.getMessage());
    }
}

 

二、構造返回數據類

/****
 * @Author:
 * @Description:返回實體Bean
 *****/
@ApiModel(description = "Result",value = "Result")
public class Result<T> {

    @ApiModelProperty(value="執行是否成功,true:成功,false:失敗",required = true)
    private boolean flag;//是否成功
    @ApiModelProperty(value="返回狀態碼,20000:成功,20001:失敗,20002:用戶名或密碼錯誤,20003:權限不足,20004:遠程調用失敗,20005:重複操作,20006:沒有對應的數據",required = true)
    private Integer code;//返回碼

    @ApiModelProperty(value="提示信息",required = true)
    private String message;//返回消息
    @ApiModelProperty(value="邏輯數據",required = true)
    private T data;//返回數據

    public Result(boolean flag, Integer code, String message, Object data) {
        this.flag = flag;
        this.code = code;
        this.message = message;
        this.data = (T) data;
    }

    public Result(boolean flag, Integer code, String message) {
        this.flag = flag;
        this.code = code;
        this.message = message;
    }

    public Result() {
        this.flag = true;
        this.code = StatusCode.OK;
        this.message = "操作成功!";
    }

    public boolean isFlag() {
        return flag;
    }

    public void setFlag(boolean flag) {
        this.flag = flag;
    }

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }
}
