如何:配置 Spring-WS 以发布带有“?WSDL"样式 URL 的 WSDL 文件? [英] Howto: Configure Spring-WS to publish WSDL files with a '?WSDL' style URL?

问题描述

我正在尝试使用 Mule ESB 配置网络服务代理.

I am trying to configure web service proxying using Mule ESB.

我正在尝试使用 Mule 的 WSProxyService 来执行此操作，但在逐步执行相应的代码(使用调试器)后，很明显该类替换了端点地址.

I am attempting to do this using Mule's WSProxyService, but after stepping through the corresponding code (with the debugger), it is clear that this class replaces endpoint addresses.

问题是 Spring-WS WSDL 地址的样式是 http://xxxx/xxxx.wsdl，但 WSProxyService 需要 http://xxxx/xxxx?wsdl 或 http://xxxx/xxxx&wsdl.它将远程端点地址替换为本地 WSDL 地址；它在问号处切断远程 WSDL 地址，即?WSDL"旨在被切断，因此创建搜索词.但是因为 Spring-WS，这行不通.

The problem is Spring-WS WSDL addresses are of the style http://xxxx/xxxx.wsdl, but WSProxyService expects http://xxxx/xxxx?wsdl or http://xxxx/xxxx&wsdl. It replaces the remote endpoint addresses with the local WSDL address; it cuts the remote WSDL address at the question mark i.e. '?WSDL' is intended to be chopped off, so to create the search term. But because of Spring-WS, this does not work.

分解:

WSProxyService 最终尝试使用

WSProxyService ends up trying to use

http://xxxx/xxxx.wsdl

替换

http://xxxx/xxxx

与

http://yyyy/yyyy

失败...导致实际的 Web 服务调用直接进行，而不是通过代理.

which fails... leading to actual web service call going direct and not through the proxy.

有没有人注意到/解决过这个问题??

Has anyone ever noticed/solved this problem??

干杯，达伦

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
    }
}
