如何在 Spring 集成中使用 JAVA 配置创建 http 出站网关？

Question

我有以下 http 出站网关。如何使用 Java Config 或 Spring DSL 进行此配置？

<int-http:outbound-gateway id="test"
                           url="http://localhost:8080/"
                           http-method="POST"
                           charset="UTF-8"
                           header-mapper="soapHeaderMapper"
                           request-factory="requestFactory"
                           request-channel="inputChannel"/>

Answer 1

@Bean
public IntegrationFlow httpOut() {
    return IntegrationFlows.from("inputChannel")
            .handle(Http.outboundGateway("http://localhost:8080/")
                    .charset("UTF-8")
                    .httpMethod(HttpMethod.POST)
                    .headerMapper(soapHeaderMapper())
                    .requestFactory(requestFactory()), e -> e.id("test"))
            .get();
}

或者

@ServiceActivator(inputChannel="inputChannel")
@Bean(name="test")
public MessageHandler httpout() {
    HttpRequestExecutingMessageHandler handler = new ...
    ...
    return handler;
}
