自定义异常处理

异常统一处理

serviceComb提供了统一的异常处理入口,可以添加自定义异常解析

如果是多个项目通用的可以写到common项目中。

  1. 添加自定义异常或者使用依赖中提供的都可以,这里已RuntimeException为示例

添加异常类 PlatformException 继承 RuntimeException

  1. 在代码中加入异常处理

public xxxx....{
        try {
            xxxxx....
        } catch (Exception e) {
            throw new PlatformException("xxxxxx");
        }
         xxxxx....
    }

  1. 添加异常处理

创建CloudPlatformExceptionToProducerResponseConverter异常处理类,implements接口ExceptionToProducerResponseConverter
泛型T 就是你要捕获的异常类

public class CloudPlatformExceptionToProducerResponseConverter implements ExceptionToProducerResponseConverter<PlatformException> {

    private static final Logger logger = LoggerFactory.getLogger(CloudPlatformExceptionToProducerResponseConverter.class);

    /**
     * 异常处理顺序
     */
    private static final int ORDER = 1;

    @Override
    public Class<PlatformException> getExceptionClass() {
        return PlatformException.class;
    }

    @Override
    public Response convert(SwaggerInvocation swaggerInvocation, PlatformException e) {
        logger.error(ExceptionUtil.getMessage(e));
        String url = ((Invocation)swaggerInvocation).getRequestEx().getRequestURI();
        logger.info("throw PlatformException error...........url....." + url);
        logger.info("throw PlatformException error...........context....." + ((Invocation) swaggerInvocation).getContext().toString());
        BaseRespResult baseRespResult = BaseRespResult.errorResult(e.getErrorCode(), e.getErrorParam(), e.getErrorMsg());
        InvocationException state = new InvocationException(javax.ws.rs.core.Response.Status.OK, baseRespResult);
        logger.error("log.isErrorEnabled():{}", logger.isErrorEnabled());
        logger.info("log.isInfoEnabled():{}", logger.isInfoEnabled());
        e.printStackTrace();
        //这行代码是将异常信息保存到平台的异常日志中
        CloudExceptionInfoStorage.saveExceptionLog(url,((Invocation) swaggerInvocation).getRequestEx().getParameterMap(),baseRespResult.getMessage(),baseRespResult.getCode(),e.getStackTrace());
        return Response.succResp(baseRespResult);
    }

    @Override
    public int getOrder() {
        return ORDER;
    }
}
  1. 配置文件添加异常引用,不然不生效

打开自己的项目(这里我截图meta,只是举例,并不是说要放到meta中),在注入异常处理配置文件中添加新添加的Converter
