This should be their own business code. I think just pay attention to :
```java
return DataBufferUtils.join(exchange.getRequest().getBody())
.flatMap(dataBuffer -> {
byte[] bytes = new
byte[dataBuffer.readableByteCount()];
dataBuffer.read(bytes);
DataBufferUtils.release(dataBuffer);
String body = Strings.fromUTF8ByteArray(bytes);
exchange.getAttributes().put(ConstantUtil.CACHE_REQUEST_BODY_OBJECT_KEY, body);
ServerHttpRequest mutatedRequest = new
ServerHttpRequestDecorator(
exchange.getRequest()) {
@Override
public Flux<DataBuffer> getBody() {
DataBuffer buffer =
exchange.getResponse().bufferFactory().wrap(bytes);
return Flux.just(buffer);
}
};
return
chain.filter(exchange.mutate().request(mutatedRequest).build());
});
```
