如何在Spring集成中使用JAVA配置创建http入站通道适配器？

Question

我有以下http入站通道适配器。如何使用Java Config或Spring DSL进行此配置？

<int-http:inbound-channel-adapter
    channel="api_app_integration_request_channel" 
    supported-methods="PUT" 
    path="/process/ticket"
    request-payload-type="*.model.Ticket"
    header-mapper="headerMapper"
    error-channel="internal-client-rest-ticket-error-channel"
>
<int-http:request-mapping consumes="application/json" />
</int-http:inbound-channel-adapter>

参见Spring Integration Reference Manual：

Java DSL：https://docs.spring.io/spring-integration/docs/current/reference/html/dsl.html#java-dsl

HTTP模块规范：https://docs.spring.io/spring-integration/docs/current/reference/html/http.html#http-java-config

您的特定示例可以转换为此IntegrationFlow

    @Bean
    public IntegrationFlow myHttpFlow() {
        return IntegrationFlows
                .from(Http.inboundChannelAdapter("/process/ticket")
                        .requestMapping(r -> r
                                .methods(HttpMethod.PUT)
                                .consumes("application/json"))
                        .requestPayloadType(model.Ticket.class)
                        .headerMapper(headerMapper))
                .channel("api_app_integration_request_channel")
                ...
                .get();
    }

您可以添加集成端点来构建处理这些请求的逻辑，而不是添加...。

在同一个HTTP章节中，您可以找到如何将HttpRequestHandlingMessagingGateway配置为纯@Bean。
