如何在Spring集成中使用JAVA配置創建http出站網關？

Question

我有以下http出站網關。我該如何使用Java Config或Spring DSL來完成此配置？

<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; 
}
