spring Cloud 全局异常捕获

通过@RestControllerAdvice来处理。

@RestControllerAdvice
public class GlobalExceptionAdvice {
 
    @ExceptionHandler(value = Exception.class)
    public ApiResult<String> handlerAdException(HttpServletRequest request, Exception ex) {
        ApiResult<String> response = new ApiResult<>();
        response.setCodeToError(ex.getMessage());
        return response;
    }
}

ApiResult 是我自己包装的返回结果

public class ApiResult<T> {
    public static final String FAIL_CODE = "0";
    public static final String SUC_CODE = "1";
    public static final String ERROR_CODE = "2";
    public static final String SUC_MESSAGE = "Operate successfully";
    public static final String FAIL_MESSAGE = "Operation failure";
    public static final String ERROR_MESSAGE = "System Error";
    public static final String NOACCESS_MESSAGE = "No permission to access this page.";
 
    private String code = FAIL_CODE;
    private String message = FAIL_MESSAGE;
    private T data;
 
    public String getCode() {
        return code;
    }
 
    public void setCode(String code) {
        this.code = code;
    }
 
    public void setCode(String code, String message) {
        this.code = code;
        this.message = message;
    }
 
    public void setCodeToSuccessed() {
        this.code = SUC_CODE;
        this.message = SUC_MESSAGE;
    }
    public void setCodeToSuccessed(T data) {
        this.data = data;
        this.code = SUC_CODE;
        this.message = SUC_MESSAGE;
    }
    
    public void setCodeToError(String message) {
        this.code = ERROR_CODE;
        this.message = message;
    }
    
    public void setCodeToError() {
        this.code = ERROR_CODE;
        this.message = ERROR_MESSAGE;
    }
 
    public void setCodeToFail(String message) {
        this.code = ERROR_CODE;
        this.message = message;
    }
 
    public void setCodeToFail() {
        this.code = FAIL_CODE;
        this.message = FAIL_MESSAGE;
    }
    
    public void setCodeByNoAccess() {
        this.code = FAIL_CODE;
        this.message = NOACCESS_MESSAGE;
    }
 
    public String getMessage() {
        return message;
    }
 
    public void setMessage(String message) {
        this.message = message;
    }
    
    public boolean isSuccess() {
        return SUC_CODE.equals(code);
    }
 
    public T getData() {
        return data;
    }
 
    public void setData(T data) {
        this.data = data;
    }
    
    
    
}
