The context is I want to migrate my Jersey Application to Spring MVC, For the Filter part, Jersey ContainerRequestContext has getEntity() function, which I can use to check response type is MyClientResponse or not

@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) {
    if (isMyClientResponse(responseContext.getEntity())) {}

but in spring Filter

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

    HttpServletRequest req = (HttpServletRequest) request;
    HttpServletResponse res = (HttpServletResponse) response;

the param HttpServletResponse doesn't have such method which I can extract the entity object from it

In Java HttpServletResponse class, I only see method like

public ServletOutputStream getOutputStream() throws IOException;

but don't see method like

public Object getEntity();

Which we can get the entity body from it, so how can we get entity from HttpServletResponse? Or is there any way to convert ServletOutputStream to Object?
