标签： java spring spring-integration

我在contexto.xml文件下面：

<?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，它标记了＆＃39; channel＆＃39;作为错误。编辑说下面的消息：

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是在运行时下面会生成异常：

    ... 14 more

如果那么我在contexto.xml文件中替换下面的起始行：

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

通过

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

然后＆＃39;频道＆＃39;已识别，编辑器不再将其标记为错误，但导入行现在标记为错误：

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，但它继续说有错误。无论如何，我可以构建和执行应用程序，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：

中添加了以下行 
  http://www.springframework.org/schema/integration
  http://www.springframework.org/schema/integration/spring-integration.xsd

添加上面两行后，在context.xml中没有标记错误，但是当我执行应用程序时，会抛出另一个异常：

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)

此外，我还尝试在contexto.xml中指定一个版本：

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文件中遗漏了一些依赖项。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>

现在它有效！ ;）

对于您正在使用的资源，您必须使用已定义的命名空间：

<int:channel id="helloWorldChannel" />
