java - Spring cvc复合型.2.4.a : Invalid content was found starting with element 'channel'

Question

我有以下 contexto.xml 文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:context="http://www.springframework.org/schema/context"
  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/context 
  http://www.springframework.org/schema/context/spring-context-3.1.xsd"
  default-init-method="iniciar" 
  default-destroy-method="destruir">

    <import resource="otherfile.xml"/>
    <import resource="otherfile2.xml"/>


<!-- other stuff -->

<!-- A Spring Integration channel -->
<int:channel id="helloWorldChannel" />

<!-- A Spring Integration adapter that routes messages sent to the helloWorldChannel to the bean named "helloServiceImpl"'s hello() method -->
<int:service-activator input-channel="helloWorldChannel" ref="helloServiceImpl" method="hello" />

在 Eclipse 中编辑此文件时，它将“ channel ”标记为错误。编辑说以下消息:

cvc-complex-type.2.4.a: Invalid content was found starting with element 'channel'. One of '{"http://
 www.springframework.org/schema/beans":import, "http://www.springframework.org/schema/beans":alias, 
 "http://www.springframework.org/schema/beans":bean, WC[##other:"http://www.springframework.org/
 schema/beans"], "http://www.springframework.org/schema/beans":beans}' is expected.

无论如何，我可以构建应用程序并执行，但在运行时会生成以下异常:

    ... 14 more

如果我替换 contexto.xml 文件中的以下起始行:

<beans xmlns="http://www.springframework.org/schema/beans"

由

<beans:beans xmlns:beans="http://www.springframework.org/schema/beans"

然后“ channel ”被识别，编辑器不再将其标记为错误，但导入行现在被标记为错误:

cvc-complex-type.2.4.a: Invalid content was found starting with element 'import'. One of '{"http://
 www.springframework.org/schema/beans":description, "http://www.springframework.org/schema/
 beans":import, "http://www.springframework.org/schema/beans":alias, "http://www.springframework.org/
 schema/beans":bean, WC[##other:"http://www.springframework.org/schema/beans"], "http://
 www.springframework.org/schema/beans":beans}' is expected.

已更新

我在chanel之前添加了int命名空间，但它仍然说有错误。无论如何，我可以构建并执行应用程序，但抛出以下异常:

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/integration]

最后，我在 xsi:schemaLocation 中添加了以下几行:

  http://www.springframework.org/schema/integration
  http://www.springframework.org/schema/integration/spring-integration.xsd

添加以上两行后，context.xml 中没有标记任何错误，但当我执行应用程序时，会引发另一个异常:

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/integration]

    at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:83)
    at com.distributed.analyzer.Main.main(Main.java:33)

我还尝试在 contexto.xml 中指定版本:

http://www.springframework.org/schema/integration/spring-integration.xsd

即:

http://www.springframework.org/schema/integration/spring-integration-1.0.xsd
http://www.springframework.org/schema/integration/spring-integration-2.0.xsd

但它不起作用，在运行时抛出相同的异常。

最后更新

maven pom.xml 文件中缺少一些依赖项。我添加了以下依赖项:

    <dependency>
        <groupId>org.springframework.integration</groupId>
        <artifactId>spring-integration-core</artifactId>
        <version>4.1.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.integration</groupId>
        <artifactId>spring-integration-jms</artifactId>
        <version>4.1.2.RELEASE</version>
    </dependency>

现在可以了! ;)

您必须根据您的情况使用为您正在使用的资源定义的命名空间:

<int:channel id="helloWorldChannel" />
