Spring-全局异常拦截

@ResponseBody
//可针对特定模块拦截
@ControllerAdvice
public class ExceptionAdvice {
    private static Logger logger = LoggerFactory.getLogger(ExceptionAdvice.class);

    /***
    * 参数绑定异常
    * @date 2018/10/16
    * @param exception HttpMessageNotReadableException
    */
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(HttpMessageNotReadableException.class)
    public Result<Long> messageNotReadable(HttpMessageNotReadableException exception){
        InvalidFormatException formatException = (InvalidFormatException)exception.getCause();
        List<JsonMappingException.Reference> e = formatException.getPath();
        String fieldName = "";
        for (JsonMappingException.Reference reference :e){

        }
        logger.error("参数不匹配"+exception);
        return Result.createFailResult(fieldName+"参数类型不匹配");
    }

    /***

    * @date 2018/10/16
    * @param e 没有匹配到的全局异常
    */
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(Exception.class)
    public Result<String> all(Exception e){
        //这里的log使用了“，”，这样能把异常的堆栈信息全部打印出来，更容易定位bug
        logger.error("异常：",e);
        return Result.createFailResult("工程抢救中……请稍后再试");
    }
}

@ControllerAdvice

@ControllerAdvice 默认监控所有的 @RequestMapping 方法，也可以对指定过滤的条件：

// 监控所有的被@RestController注解的Controllers类 
@ControllerAdvice(annotations = RestController.class)

// 监控特定的包下的Controllers类
@ControllerAdvice("org.example.controllers")

// 监控指定类的Controllers类
@ControllerAdvice(assignableTypes = {ControllerInterface.class, AbstractController.class})
