study-renjie opened a new issue, #3931:
URL: https://github.com/apache/servicecomb-java-chassis/issues/3931
在使用CSERestTemplate进行请求，并且通过JAVASPI使用拦截器ClientHttpRequestInterceptor对请求进行拦截时，存在强转异常，CSE不兼容Spring的原生拦截功能。
报错如下：
`Failed to execute http request. Exception: {}
java.lang.ClassCastException:
org.springframework.http.client.InterceptingClientHttpRequest cannot be cast to
org.apache.servicecomb.provider.springmvc.reference.CseClientHttpRequest
at
org.springframework.web.client.CseHttpMessageConverter.write(CseHttpMessageConverter.java:77)
~[provider-springmvc-1.3.0.B012.jar:5.3.27]`
问题代码
org.springframework:spring-web:5.3.27
778-782行
`
ClientHttpRequest request = createRequest(url, method);
if (requestCallback != null) {
requestCallback.doWithRequest(request);
}
response = request.execute();
`
在CSERestTemplate重写了doWithRequest，里面存在强转逻辑
`
/**
* {@inheritDoc}
*/
@Override
public void doWithRequest(ClientHttpRequest request) throws IOException {
orgCallback.doWithRequest(request);
if (!CseHttpEntity.class.isInstance(requestBody)) {
return;
}
CseClientHttpRequest req = (CseClientHttpRequest) request;
CseHttpEntity<?> entity = (CseHttpEntity<?>) requestBody;
req.setContext(entity.getContext());
}
`
