【Spring】SpringBoot 全局异常捕获和处理

一、编写全局异常捕获的类

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

二、构造返回数据类

/***** @Author:* @Description:返回实体Bean*****/
@ApiModel(description = "Result",value = "Result")
public class Result<T> {@ApiModelProperty(value="执行是否成功,true:成功,false:失败",required = true)private boolean flag;//是否成功@ApiModelProperty(value="返回状态码,20000:成功,20001:失败,20002:用户名或密码错误,20003:权限不足,20004:远程调用失败,20005:重复操作,20006:没有对应的数据",required = true)private Integer code;//返回码@ApiModelProperty(value="提示信息",required = true)private String message;//返回消息@ApiModelProperty(value="逻辑数据",required = true)private T data;//返回数据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;}
}
