Spring WS servlet 前面的 servlet 过滤器如何检查 url 和 params?

How about a servlet filter in front of the Spring WS servlet that checks the url and the params?

如果匹配，则返回 WSDL，否则就让请求通过，就好像什么都没发生一样.

In case of a match, you return the WSDL, otherwise you let the request through as if nothing happened.

这应该很容易实现并且可以满足您的需求，如果您绝对必须将 WS + ?WSDL 的 url 附加到它.

This should be trivial to implement and will fill your need, if you absolutely must have the url of the WS + ?WSDL appended to it.

代码如下:

public class WsdlQueryCompatibilityFilter implements Filter {
    @Override
    public void init(final FilterConfig filterConfig) throws ServletException {
        // do nothing
    }

    @Override
    public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain)
            throws IOException, ServletException {
        final HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        if ("GET".equals(httpServletRequest.getMethod())
                && "wsdl".equalsIgnoreCase(httpServletRequest.getQueryString())) {
            httpServletRequest.getSession().getServletContext().getRequestDispatcher("/ws.wsdl")
                    .forward(request, response);
        } else {
            chain.doFilter(request, response);
        }
    }

    @Override
    public void destroy() {
        // do nothing
    }
}
