我正在尝试使用 Java DSL 为 HTTP 入站网关创建和注册运行时集成流,如下所示
@Autowired
private IntegrationFlowContext flowContext;
public static void main(String[] args) {
SpringApplication.run(RestClientDemoApplication.class, args);
}
@ServiceActivator(inputChannel="httpRequest")
public String upCase(String in) {
System.out.println("message received" + in);
return in.toUpperCase();
}
@Bean
public MessageChannel directChannel(){
return MessageChannels.direct().get();
}
/*@Bean
public IntegrationFlow inbound() {
return IntegrationFlows.from(Http.inboundGateway("/foo")
.requestMapping(m -> m.methods(HttpMethod.POST))
.requestPayloadType(String.class).replyChannel(directChannel()))
.channel("httpRequest")
.get();
}
*/
@Override
public void run(String... args) throws Exception {
IntegrationFlow flow;
IntegrationFlowRegistration theFlow;
flow = IntegrationFlows.from(Http.inboundGateway("/foo")
.requestMapping(m -> m.methods(HttpMethod.POST))
.requestPayloadType(String.class).replyChannel(directChannel()))
.channel("httpRequest")
.get();
theFlow = this.flowContext.registration(flow).register();
}
在这种情况下,我的请求 url ("/foo") 没有与服务器映射,因为当我从 HTTP 客户端发送消息时,服务器端没有收到任何消息。但是当我取消注释上面的bean(入站),即为集成流创建一个bean并在运行方法中 注释流创建和注册代码(删除运行时集成流代码)时,它工作正常:
@Autowired
private IntegrationFlowContext flowContext;
public static void main(String[] args) {
SpringApplication.run(RestClientDemoApplication.class, args);
}
@ServiceActivator(inputChannel="httpRequest")
public String upCase(String in) {
System.out.println("message received" + in);
return in.toUpperCase();
}
@Bean
public MessageChannel directChannel(){
return MessageChannels.direct().get();
}
@Bean
public IntegrationFlow inbound() {
return IntegrationFlows.from(Http.inboundGateway("/foo")
.requestMapping(m -> m.methods(HttpMethod.POST))
.requestPayloadType(String.class).replyChannel(directChannel()))
.channel("httpRequest")
.get();
}
@Override
public void run(String... args) throws Exception {
/*IntegrationFlow flow;
IntegrationFlowRegistration theFlow;
flow = IntegrationFlows.from(Http.inboundGateway("/foo")
.requestMapping(m -> m.methods(HttpMethod.POST))
.requestPayloadType(String.class).replyChannel(directChannel()))
.channel("httpRequest")
.get();
theFlow = this.flowContext.registration(flow).register();*/
}
我的 HTTP 出站网关代码如下
flow = IntegrationFlows.from(directChannel()).handle(Http.outboundGateway("https://localhost:8448/foo")
.httpMethod(HttpMethod.POST).expectedResponseType(String.class)).channel("httpReply").get();
theFlow = this.flowContext.registration(flow).register();
如果这种方法不合适,请帮助我解决上述问题或提供在运行时创建 Http 入站网关的解决方案。
