我正在使用Spring Integration进行REST调用,如下所示。持续连接/使用Spring Integration客户端连接重用
<int:gateway id="ServiceRequestGateway"
service-interface="com.company.security.integration.RequestGateway"
default-request-channel="RequestChannel"
default-reply-channel="ResponseChannel">
<int:default-header name="Accept" value="application/json; v=5"/>
<int:default-header name="Content-Type" value="application/json; v=5"/>
<int:default-header name="ServiceType" expression="#args[1]"/>
</int:gateway>
<int-http:outbound-gateway
id="Outbound_Gateway"
request-channel="RequestChannel"
reply-channel="ResponseChannel"
header-mapper="headerMapper"
url="${service.host}/{xyzServiceType}"
http-method="POST"
expected-response-type="java.lang.String"
extract-request-payload="true">
<int-http:uri-variable name="ServiceType" expression="headers['xyzServiceType']" />
</int-http:outbound-gateway>
但是,在网络上的每个呼叫都会发生很多ssl握手。我如何重用连接并发出多个REST请求?有没有可能使用保持活力?

添加使用HttpComponentsClientHttpRequestFactory的。
<int-http:outbound-gateway
id="NPI_Tokenization_Outbound_Gateway"
request-channel="NPITokenizationRequestChannel"
reply-channel="ResponseChannel"
header-mapper="headerMapper"
url="${npi.turing.host}/{npiTuringType}"
http-method="POST"
expected-response-type="java.lang.String"
extract-request-payload="true">
<int-http:uri-variable name="npiTuringType" expression="headers['npiTuringType']" />
</int-http:outbound-gateway>
<bean id="requestFactory"
class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="connectTimeout" value="5000"/>
<property name="readTimeout" value="5000"/>
</bean>
请参见[此答案](http://stackoverflow.com/questions/35185025/default-keep-alive-time-for-a -httpconnection-when-using-spring-rest-template)获取更多链接。 –
谢谢,我添加了HttpComponentsClientHttpRequestFactory(更新了我上面的问题),但是我没有看到有关如何在Spring集成环境中配置保持活动的属性/示例 –
已不是Spring集成责任。您必须从''添加'request-factory'引用。所有的事情都取决于'HttpComponentsClientHttpRequestFactory'配置。对我来说,我们给了你足够的链接来阅读这件事...... –
