springBoot-统一异常处理实现

实现模块：

1.定义响应数据格式

• 常量

public interface Conf {/*** 成功标记*/Integer SUCCESS = 0;/*** 失败标记*/Integer FAIL = 1;
}

• 响应体

/*** 响应信息主体** @param * @author guiyun*/
@Builder
@ToString
@NoArgsConstructor
@AllArgsConstructor
@Accessors(chain = true)
public class R<T> implements Serializable {private static final long serialVersionUID = 1L;@Getter@Setter
//	@ApiModelProperty(value = "返回标记：成功标记=0，失败标记=1")private int code;@Getter@Setter
//	@ApiModelProperty(value = "返回信息")private String msg;@Getter@Setter
//	@ApiModelProperty(value = "数据")private T data;public static <T> R<T> ok() {return restResult(null, Conf.SUCCESS, null);}public static <T> R<T> ok(T data) {return restResult(data, Conf.SUCCESS, null);}public static <T> R<T> ok(T data, String msg) {return restResult(data, Conf.SUCCESS, msg);}public static <T> R<T> failed() {return restResult(null, Conf.FAIL, null);}public static <T> R<T> failed(String msg) {return restResult(null, Conf.FAIL, msg);}public static <T> R<T> failed(T data) {return restResult(data, Conf.FAIL, null);}public static <T> R<T> failed(T data, String msg) {return restResult(data, Conf.FAIL, msg);}private static <T> R<T> restResult(T data, int code, String msg) {R<T> apiResult = new R<>();apiResult.setCode(code);apiResult.setData(data);apiResult.setMsg(msg);return apiResult;}}

2.自定义异常类与全局异常拦截

• 自定义异常类

/*** 基础异常* */
public class BaseException extends RuntimeException {private static final long serialVersionUID = 1L;/*** 所属模块*/private String module;/*** 错误码*/private Integer code;/*** 错误码对应的参数*/private Object[] args;/*** 错误消息*/private String defaultMessage;public BaseException(String module, Integer code, Object[] args, String defaultMessage) {this.module = module;this.code = code;this.args = args;this.defaultMessage = defaultMessage;}public BaseException(String module, Integer code, Object[] args) {this(module, code, args, null);}public BaseException(Integer code, String defaultMessage) {this(null, code, null, defaultMessage);}public BaseException(Integer code, Object[] args) {this(null, code, args, null);}public BaseException(String defaultMessage) {this(null, Conf.FAIL, null, defaultMessage); // 默认给 0}@Overridepublic String getMessage() {// 以后开启国际化/** String message = null; if (!StringUtils.isEmpty(code)) { message =* MessageUtils.message(code, args); } if (message == null) { message =* defaultMessage; }*/return defaultMessage;}public String getModule() {return module;}public Integer getCode() {return code;}public Object[] getArgs() {return args;}public String getDefaultMessage() {return defaultMessage;}
}

• 全局异常拦截

package com.guiyun.exception;
/*** 全局异常拦截* * @author 29631**/
@ControllerAdvice
public class DefaultExceptionHandler {Logger logger = LoggerFactory.getLogger(DefaultExceptionHandler.class);/*** 基础异常*/@ExceptionHandler(BaseException.class)@ResponseBodypublic R<?> baseException(BaseException e) {logger.error(e.getMessage());R<?> result = new R<>();result.setMsg(e.getDefaultMessage());return result;}/*** 时间日期解析错误*/@ExceptionHandler(ParseException.class)public R<?> parseException(ParseException e) {logger.error(e.getMessage(), e);R<?> result = new R<>();result.setMsg(e.getMessage());return result;}/*** 拦截Exception类的异常* * @param e* @return*/@ExceptionHandler(Exception.class)@ResponseBodypublic R<?> exceptionHandler(Exception e, HttpServletRequest request) {logger.error("异常:" + e.getMessage(), e);R<?> result = new R<>();result.setMsg("系统异常，请稍后再试！");return result;}}

原理模块等有时间再补上
