无法为XML架构命名空间[http://www.springframework.org/schema/integration/ip定位NamespaceHandler

Question

嗨，你能帮我一下吗？我在中使用Spring4.3.8。我得到了这个异常: org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题:无法为XML模式命名空间[http://www.springframework.org/schema/integration/ip]定位[http://www.springframework.org/schema/integration/ip]：类路径资源[http://www.springframework.org/schema/integration/ip]-config.xml

Maven配置：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-integration</artifactId>
</dependency>

我的Spring配置是：

<?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"

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">

<context:property-placeholder location="classpath:udp-server.properties" />

<bean id="udpConsumer" class="com.example.udp.UDPConsumer" />

<int:channel id="inputChannel">
    <int:queue />
</int:channel>

<int-ip:udp-inbound-channel-adapter id="udpReceiver"
    channel="inputChannel"
    port="${udp-server.port}"
    pool-size="${udp-server.threads}"
    receive-buffer-size="${udp-server.buffer-size}"
    multicast="false"
    check-length="true"/>

<int:service-activator input-channel="inputChannel"
    ref="udpConsumer" />

<int:poller default="true" fixed-rate="500" />

集成入门器只引入spring-integration-core jar，以避免不需要的jar类路径膨胀；您需要添加

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-ip</artifactId>
</dependency>

Boot/Maven将引入与核心匹配的正确版本。
