用Spring集成问题配置TCP通信

Question

我似乎在将Spring后端配置为接收和发送TCP消息时遇到了一些困难。看看用户在这个问题中建议的配置-- how to plug a TCP-IP client server in a spring MVC application --我尝试将这个配置放到我的root-context.xml中。但是，对于所有标记，它都会显示一条消息，如：

Unable to locate Spring NamespaceHandler for element 'int-ip:tcp-outbound-gateway' of schema namespace 'http://www.springframework.org/schema/integration/ip'

int-ip:tcp-outbound-gateway和int:gateway都显示cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'int:gateway' (用int-ip:tcp-outbound-gateway代替int:gateway )。

这是我的root-context.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/integration/ip http://www.springframework.org/schema/integration/ip/spring-integration-ip.xsd
                        http://www.springframework.org/schema/integration/ http://www.springframework.org/schema/integration/spring-integration.xsd">

    <!-- Root Context: defines shared resources visible to all other web components -->
    <int:gateway id="gw"
    service-interface="org.springframework.integration.samples.tcpclientserver.SimpleGateway"
    default-request-channel="input"/>

    <int-ip:tcp-connection-factory id="client"
        type="client"
        host="localhost"
        port="1234"
        single-use="true"
        so-timeout="10000"/>

    <int:channel id="input" />

    <int-ip:tcp-outbound-gateway id="outGateway"
        request-channel="input"
        reply-channel="clientBytes2StringChannel"
        connection-factory="client"
        request-timeout="10000"
        remote-timeout="10000"/>

    <int:transformer id="clientBytes2String"
        input-channel="clientBytes2StringChannel"
        expression="new String(payload)"/>

</beans>

我做错什么了？此外，一些关于如何使用Spring发送和接收TCP通信的一般技巧也将受到欢迎:)

您的类路径上似乎没有spring-integration-ip和spring-integration-core jars。您需要将它们捆绑到war中，或者根据应用服务器的要求在类路径上提供它们。
