Java 使用Spring boot 2.0.0仅在响应时执行GenericFilterBean

我已经看到，如果我注册一个Spring

GenericFilterBean

类，它会在每次请求时调用。只有当服务返回响应时，才可以调用另一个筛选器（可能是另一个

GeneircFilterBean

）吗？基本上，我希望实现与Jersey

ContainerResponseFilter

相同的行为

提前感谢

您可以在chain.doFilter（请求、响应）方法之后传递代码。 下面是一个例子

public class SimpleLoggingFilter extends GenericFilterBean {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        chain.doFilter(request, response);
//This code will work after response
        if ((response instanceof HttpServletResponse) && (request instanceof HttpServletRequest))  {           
            HttpServletResponse httpServletResponse = (HttpServletResponse) response;
            System.out.println("Response status is " + httpServletResponse.getStatus() +" " +
                    "Response  content-length is " + httpServletResponse.getHeader("content-length"));
        }
    }
}
