Spring cloud project, using the gateway gateway, through a method call forward gateway interface can't receive the information returned, Java is normal background data processing, direct call target interface, can receive return information, what reason is this excuse me? Gateway returns information is how to deal with it?

 
Public Mono The filter (ServerWebExchange exchange, GatewayFilterChain chain) {
ServerHttpResponse originalResponse=exchange. The method getResponse (); 
DataBufferFactory bufferFactory=originalResponse. BufferFactory (); 
ServerHttpResponseDecorator decoratedResponse=new ServerHttpResponseDecorator (originalResponse) {
@ Override 
Public Mono WriteWith (Publisher<? Extends DataBuffer> Body) {
If (body instanceof Flux) {
Flux<? Extends DataBuffer> FluxBody=(Flux<? Extends DataBuffer>) The body; 
Return super. WriteWith (fluxBody. The map (dataBuffer - & gt; {
//probably should reuse buffers 
Byte [] the content=new byte [dataBuffer readableByteCount ()]; 
DataBuffer. Read (content); 
//release memory 
DataBufferUtils. Release (dataBuffer); 
String s=new String (the content, the Charset. Class.forname (" utf-8 ")); 
//TODO, s is the value of the response 
Byte [] uppedContent=new String (the content, the Charset. Class.forname (" utf-8 ")). GetBytes (); 
Return bufferFactory. Wrap (uppedContent); 
})); 
} 
//if the body is not a flux. Never got there. 
Return super. WriteWith (body); 
} 
}; 
//replace the response with the decorator 
Return chain. The filter (exchange. Mutate (). The response (decoratedResponse). The build ()); 
} 

View the return information, found that the contentType is null?

Remove the filter you configured to direct, to test, should be the filter you have any question, enhance the log, recording analysis analysis

To check the reason, request brought Expect=100 - continue inside, cause the request does not return, after removing it
