我使用以下弹簧集成进行休息呼叫。
<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,网络上的每个呼叫都会发生很多SSL握手。如何重复使用连接并提出多个休息请求?是否可以使用饲养场?

添加了httpcomponentsclienthttprequestfactory的使用。
<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>
考虑使用HttpComponentsClientHttpRequestFactory
而不是默认的SimpleClientHttpRequestFactory
。在Apache HTTP客户端中,您可以找到足够的连接管理选项,包括keep-alive
