在当前模型中,我们有一个REST端点,该端点获取请求正文,并基于该端点创建一个jms文本消息并将其发送到JMS队列,
TextMessage outMessage = session.createTextMessage(messagePayloadText);
..
outMessage.setStringProperty("clientType", clientType);
outMessage.setStringProperty("DYNAMIC", dynaHeader);
在上面的代码中,需要DYNAMIC来帮助我创建我们的网址
<int:chain input-channel="gCStatusInChannel" output-channel="headerFilterChannel">
<int:header-enricher>
<int:header name="Api-Key" value="B8872853E8B"></int:header>
<int:header name="Accept" value="application/json" />
<int:header name="Content-Type" value="application/json" />
</int:header-enricher>
<int-http:outbound-gateway
url="https://i-zaie.sr13.tst.bst/ia-zaaie/rest/search/v2/cReference/{cref}"
http-method="PUT"
header-mapper="headerMapper"
expected-response-type="java.lang.String"
encode-uri="false"
request-factory="sslFactory">
<int-http:uri-variable name="cref" expression="headers['DYNAMIC']" />
</int-http:outbound-gateway>
<int:object-to-string-transformer></int:object-to-string-transformer>
</int:chain>
一切都适用于此模型。现在我要使用网关而不是JMS
新代码:
<int:gateway id="gService"
service-interface="n.d.lr.eai.gw.GGateway"
default-reply-channel="dest-channel"
default-request-timeout="5000" default-reply-timeout="5000">
<int:method name="vCreateSignal" request-channel="vCreateSignalInChannel"/> ...
问题: 我可以在网关中使用以下方法吗?
public String vCreateSignal(String caseDat, String dynamic);
我应该怎么做才能启用
<int:chain input-channel="gCStatusInChannel"...
..>
获取标题['DYNAMIC']值并继续。
答案 0 :(得分:1)
是的,您可以这样做。您只需要在该@Header("DYNAMIC")
参数中添加一个dynamic
:
public String vCreateSignal(String caseDat, @Header("DYNAMIC") String dynamic);
当您调用此网关的方法时,您只需指定一个参数,它将被映射到适当的标头,并且所有参数:https://docs.spring.io/spring-integration/docs/current/reference/html/messaging-endpoints-chapter.html#gateway-mapping
