[GitHub] [servicecomb-java-chassis] huanghezhen opened a new issue #1740: 在 highway 模式下 自定义ExceptionToProducerResponseConverter 返回对象序列化失败
huanghezhen opened a new issue #1740:
URL: https://github.com/apache/servicecomb-java-chassis/issues/1740
```java
public class GlobalExceptionFilter implements ExceptionToProducerResponseConverter<Exception> {
@Override
public Class<Exception> getExceptionClass() {
return Exception.class;
}
@Override
public Response convert(SwaggerInvocation swaggerInvocation, Exception e) {
System.out.println("----------------------------------------------------------");
//String s = JSONObject.toJSONString(BaseResponse.newInstance(CommonResponseMsg.ERROR));
return Response
.create(HttpStatus.SC_OK, String.valueOf(HttpStatus.SC_OK), BaseResponse.newInstance(CommonResponseMsg.ERROR));
}
}
```
> BaseResponse.newInstance(CommonResponseMsg.ERROR) 这个是自定义返回信息对象
当rpc 抛出 Exception 异常的时候,会得到如下json数据
```json
{
"message": "method POST, path /ProviderServiceImpl/testException/, statusCode 200, reasonPhrase 200, response content-type application/json; charset=utf-8 is not supported"
}
```
> 如下是期望的返回json数据
```json
{
"status": false,
"resultCode": "0000000",
"logicCode": "000000001",
"resultMsg": "接口异常"
}
```
