[英]Spring Integration TCP server: Get the Ip address & the payload
我刚开始使用Spring-Integration,并实现了TCP服务器,该服务器仅向客户端发送“ OK”消息。 我想记录客户端IP地址和从客户端收到的文本。
我可以使用以下配置文件成功获取客户端发送的文本,但是我不知道如何获取客户端的IP地址。
下面是TCP服务器的配置文件。
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:int="http://www.springframework.org/schema/integration"
xmlns:int-ip="http://www.springframework.org/schema/integration/ip"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd
http://www.springframework.org/schema/integration/ip http://www.springframework.org/schema/integration/ip/spring-integration-ip.xsd">
<context:property-placeholder />
<int-ip:tcp-connection-factory id="tcpServer"
type="server"
using-nio="true"
port="${tcpServer.port}"/>
<int-ip:tcp-inbound-gateway id="tcpGateway"
connection-factory="tcpServer"
request-channel="bytesChannel"
error-channel="errorChannel"/>
<int:service-activator input-channel="inputChannel" ref="myTcpService" method="processInput"/>
<bean id="myTcpService" class="MyTcpService" />
<int:transformer id="transformerBytes2String"
input-channel="bytesChannel"
output-channel="inputChannel"
expression="new String(payload)"/>
<int:transformer id="errorHandler"
input-channel="errorChannel"
expression="payload.failedMessage.payload + ':' + payload.cause.message"/>
<int:channel id="inputChannel" />
<int:channel id="bytesChannel"/>
</beans>
MyTcpService类:
public class MyTcpService {
public String processInput(String input){
return "OK";
}
}
我想知道是否有可能在“ processInput”方法中获得IP地址以及有效载荷。
几个连接属性存储在MessageHeaders
( TcpMessageMapper
)中:
messageBuilder
.setHeader(IpHeaders.HOSTNAME, connection.getHostName())
.setHeader(IpHeaders.IP_ADDRESS, connection.getHostAddress())
.setHeader(IpHeaders.REMOTE_PORT, connection.getPort())
.setHeader(IpHeaders.CONNECTION_ID, connectionId);
因此,您可以简单地在processInput
方法中再添加一个参数,以从所需的标头中获取一个值:
public String processInput(String input, @Header(IpHeaders.IP_ADDRESS) String ip){
当input
参数没有任何注释时,仍映射到payload
。
