Apache Camel Spring配置错误 - 无法找到XML名称空间的Spring NamespaceHandler [http://camel.apache.org/schema/spring]

Question

我已经发布了一个摘自我的spring.xml文件和堆栈跟踪I好了。

<?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:lang="http://www.springframework.org/schema/lang" 
    xmlns:util="http://www.springframework.org/schema/util" xmlns:jaxws="http://cxf.apache.org/jaxws" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 
    http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-2.5.xsd 
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd 
    http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd 
    http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring-2.0.0.xsd" 
    default-init-method="init" default-lazy-init="false"> 

    <!-- import web service configuration --> 
    <import resource="classpath:META-INF/cxf/cxf.xml" /> 
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> 
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> 

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring"> 
     <package>com.testdomain.testpackage</package> 
    </camelContext> 
... 
</beans> 

会抛出该异常：

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener 
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://camel.apache.org/schema/spring]

    at....... 

有人可以请帮助那里的问题是什么？

Answer 1

我失踪了camel-spring.jar。 我加了它，一切正常。

如果构建一个JAR使用Maven Assembly插件，然后尝试树荫插件:)

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-shade-plugin</artifactId> 
    <configuration> 
     <filters> 
      <filter> 
       <artifact>*:*</artifact> 
       <excludes> 
        <exclude>META-INF/*.SF</exclude> 
        <exclude>META-INF/*.DSA</exclude> 
        <exclude>META-INF/*.RSA</exclude> 
       </excludes> 
      </filter> 
     </filters> 
    </configuration> 
    <executions> 
     <execution> 
      <phase>package</phase>
