取消阻止来自servelt过滤器的PROPFIND http-method

Question

我做了一个过滤器，并在web.xml上注册，当我试图过滤PROPFIND抛出500内部服务器错误的http请求。这段代码可以很好地用于任何其他http方法。我想要有405的响应码

if (httpRequest.getMethod()==”PROPFIND”) {
HttpServletResponse respProp = (HttpServletResponse) response;
respProp.sendError(405);
chain.doFilter(request, respProp);
} else {
chain.doFilter(request, response);

获取java.lang.IllegalStateException时出错:在org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:462)处的javax.servlet.http.HttpServletResponseWrapper.sendError(HttpServletResponseWrapper.java:120)处的javax.servlet.http.HttpServlet.service(HttpServlet.java:673)处的org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:812)处提交响应后，无法调用sendError()

Answer 1

Instead of sending error i have sent 405 as response and my problem got solved 

    if (httpRequest.getMethod()==”PROPFIND”) {
    HttpServletResponse resp = (HttpServletResponse) response;                              
    resp.setStatus(HttpServletResponse.SC_METHOD_NOT_ALLOWED);
    } else {
    chain.doFilter(request, response);
    }
