Using the Java DSL for TCP Components
DSL support for TCP components includes specs for adapters and gateways, the Tcp
class with factory methods to create connection factory beans, and the TcpCodecs
class with factory methods to create serializers and deserializers.
Refer to their javadocs for more information.
Here are some examples of using the DSL to configure flows using the DSL.
Server Adapter Flow
@Bean
public IntegrationFlow server() {
return IntegrationFlow.from(Tcp.inboundAdapter(Tcp.netServer(1234)
.deserializer(TcpCodecs.lengthHeader1())
.backlog(30))
.errorChannel("tcpIn.errorChannel")
.id("tcpIn"))
.transform(Transformers.objectToString())
.channel("tcpInbound")
.get();
}
Client Adapter Flow
@Bean
public IntegrationFlow client() {
return f -> f.handle(Tcp.outboundAdapter(Tcp.nioClient("localhost", 1234)
.serializer(TcpCodecs.lengthHeader1())));
}
Server Gateway Flow
@Bean
public IntegrationFlow server() {
return IntegrationFlow.from(Tcp.inboundGateway(Tcp.netServer(1234)
.deserializer(TcpCodecs.lengthHeader1())
.serializer(TcpCodecs.lengthHeader1())
.backlog(30))
.errorChannel("tcpIn.errorChannel")
.id("tcpIn"))
.transform(Transformers.objectToString())
.channel("tcpInbound")
.get();
}
Client Gateway Flow
@Bean
public IntegrationFlow client() {
return f -> f.handle(Tcp.outboundGateway(Tcp.nioClient("localhost", 1234)
.deserializer(TcpCodecs.lengthHeader1())
.serializer(TcpCodecs.lengthHeader1())));
}
