Spring Cloud 集成 WebHook 1.配置 WebHook 地址登录 GitHub，点击 GitHub 的 WebHook 菜单，右侧面板中 Payload URL 填写 <配置中心 url>/actuator/bus-refresh, Content-type 选择 applicaton/json，保存即可。因为需要用到外网，这里使用natapp外网穿透做外网映射设置 WebHook 操作： 2.修改config-server添加：import org.springframework.stereotype.Component;import javax.servlet.*;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletRequestWrapper;import java.io.ByteArrayInputStream;import java.io.IOException;@Componentpublic class WebHookFilter implements Filter {    @Override     public void init(FilterConfig filterConfig) throws ServletException {     }    @Override     public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)             throws IOException, ServletException {         HttpServletRequest httpServletRequest = (HttpServletRequest) request;         String url = new String(httpServletRequest.getRequestURI());        // 只过滤 /actuator/bus-refresh 请求         if (!url.endsWith("/actuator/bus-refresh")) {             chain.doFilter(request, response);            return;         }        // 使用 HttpServletRequest 包装原始请求达到修改 post 请求中 body 内容的目的         CustometRequestWrapper requestWrapper = new CustometRequestWrapper(httpServletRequest);         chain.doFilter(requestWrapper, response);     }    @Override     public void destroy() {     }    private class CustometRequestWrapper extends HttpServletRequestWrapper {        public CustometRequestWrapper(HttpServletRequest request) {            super(request);         }        @Override         public ServletInputStream getInputStream() throws IOException {            byte[] bytes = new byte[0];             ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);            return new ServletInputStream() {                @Override                 public boolean isFinished() {                    return byteArrayInputStream.read() == -1 ? true : false;                 }                @Override                 public boolean isReady() {                    return false;                 }                @Override                 public void setReadListener(ReadListener readListener) {                 }                @Override                 public int read() throws IOException {                    return byteArrayInputStream.read();                 }             };         }     } }  3.测试 完成以上配置后，重启项目 修改github文件 再执行 http://localhost/test/getConfigInfo 因为网络原因，等几秒钟加载几次就能拉去新的数据了
