Spring集成：int-http：带有url路径变量的入站网关

Question

我正在尝试使用Spring Integration int-http：inbound-gateway测试Inbound http gatway：

<int-http:inbound-gateway id="correlateOutgoingMessage"
    supported-methods="POST" request-channel="toOutCorrelator"
    reply-channel="fromOutCorrelator" view-name="/correlateOutgoingMessage"
    path="/correlateOut/{origin}/{msgtype}/{priority}"
    reply-timeout="50000">
    <int-http:header name="origin" expression="#pathVariables.origin" />
    <int-http:header name="msgtype" expression="#pathVariables.msgtype" />
    <int-http:header name="priority" expression="#pathVariables.priority" />
</int-http:inbound-gateway>

我的Web.xml：

<servlet>
    <servlet-name>correlateOut</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/intg-schema.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>correlateOut</servlet-name>
    <!-- controler/* -->
    <url-pattern>/correlateOut/*</url-pattern>
</servlet-mapping>

使用RestTemplate，我试图向网关发出POST请求：

那个

uri =  "http://localhost:8080/test/correlateOutgoingMessage/{origin}/{msgtype}/{priority}"

    String origin = "xxxx";
    Integer msgtype = 2333;
    Integer priority = 2;

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.TEXT_PLAIN);

    HttpEntity<?> request = null;

    ResponseEntity<String> httpResponse = null;

    request = new HttpEntity<Object>(messageContent);


    httpResponse = template.exchange(uri, HttpMethod.POST, request,
            String.class, getUrlParams(origin, msgtype, priority));

我总是得到没有找到404，你能给我一些提示吗？

非常感谢！

首先，您应该显示用于发送HTTP请求的uri。

从另一端，如果您将servlet映射到/correlateOut/*，则不得在目标映射中使用它，因为所有其他endpoint都在该上下文下。

因此，您的< code>path应该是< code > path = " { origin }/{ msgtype }/{ priority } "
