Spring Boot全局統一異常處理器
一、封裝統一返回結果類
import com.jiusen.exercise.enums.ErrorEnum; import com.jiusen.exercise.exception.BusinessException; import lombok.Getter; import lombok.Setter; /** * @author: Lawson * @date: 2021/5/11 * @description: TODO 統一的返回結果 */ @Getter @Setter public class AjaxResult { //是否成功 private Boolean success; //狀態碼 private Integer code; //提示信息 private String msg; //數據 private Object data; public AjaxResult() { } //自定義返回結果的構造方法 public AjaxResult(Boolean success, Integer code, String msg, Object data) { this.success = success; this.code = code; this.msg = msg; this.data = data; } //自定義異常返回的結果 public static AjaxResult defineError(BusinessException de) { AjaxResult result = new AjaxResult(); result.setSuccess(false); result.setCode(de.getErrorCode()); result.setMsg(de.getErrorMsg()); result.setData(null); return result; } //其他異常處理方法返回的結果 public static AjaxResult otherError(ErrorEnum errorEnum){ AjaxResult result = new AjaxResult(); result.setMsg(errorEnum.getErrorMsg()); result.setCode(errorEnum.getErrorCode()); result.setSuccess(false); result.setData(null); return result; } }
二、自定義異常封裝類
import lombok.Getter; import lombok.Setter; /** * @author: Lawson * @date: 2021/5/11 * @description: TODO 類描述 */ @Getter @Setter public class BusinessException extends RuntimeException{ private static final long serialVersionUID = 1L; /** * 錯誤狀態碼 */ protected Integer errorCode; /** * 錯誤提示 */ protected String errorMsg; public BusinessException() { } public BusinessException(String message, Integer errorCode, String errorMsg) { super(message); this.errorCode = errorCode; this.errorMsg = errorMsg; } }
三、錯誤枚舉
** * @author: Lawson * @date: 2021/5/11 * @description: TODO 類描述 */ public enum ErrorEnum { //數據操作錯誤定義 SUCCESS(200, "成功"), NO_PERMISSION(403, "你無權訪問"), NO_Auth(401, "未授權,請登錄驗證"), NO_FOUND(404, "未找到資源"), INTERNAL_SERVER_ERROR(500, "服務器異常, 請聯系管理員!"); /** * 錯誤碼 */ private Integer errorCode; /** * 錯誤信息 */ private String errorMsg; ErrorEnum(Integer errorCode, String errorMsg) { this.errorCode = errorCode; this.errorMsg = errorMsg; } public Integer getErrorCode() { return errorCode; } public String getErrorMsg() { return errorMsg; } }
四、全局異常處理類
import com.jiusen.exercise.enums.ErrorEnum; import com.jiusen.exercise.exception.BusinessException; import com.jiusen.exercise.rest.AjaxResult; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.RestControllerAdvice; /** * @author: Lawson * @date: 2021/5/11 * @description: TODO 類描述 */ @RestControllerAdvice public class GlobalExceptionHandler { private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class); /** * 處理自定義異常 * @param e * @return */ @ExceptionHandler(value = BusinessException.class) public AjaxResult bizExceptionHandler(BusinessException e) { log.error(e.getErrorMsg(), e); return AjaxResult.defineError(e); } /** * 處理其它異常 */ @ExceptionHandler(value = Exception.class) public AjaxResult exceptionHandler(Exception e) { log.error(e.getMessage(), e); return AjaxResult.otherError(ErrorEnum.INTERNAL_SERVER_ERROR); } }
五、測試
import com.jiusen.exercise.enums.ErrorEnum; import com.jiusen.exercise.exception.BusinessException; import com.jiusen.exercise.rest.AjaxResult; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.RestControllerAdvice; /** * @author: Lawson * @date: 2021/5/11 * @description: TODO 類描述 */ @RestControllerAdvice public class GlobalExceptionHandler { private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class); /** * 處理自定義異常 * @param e * @return */ @ExceptionHandler(value = BusinessException.class) public AjaxResult bizExceptionHandler(BusinessException e) { log.error(e.getErrorMsg(), e); return AjaxResult.defineError(e); } /** * 處理其它異常 */ @ExceptionHandler(value = Exception.class) public AjaxResult exceptionHandler(Exception e) { log.error(e.getMessage(), e); return AjaxResult.otherError(ErrorEnum.INTERNAL_SERVER_ERROR); } }
