找不到 XML 模式命名空间的 Spring NamespaceHandler [http://activemq.apache.org/schema/core]

Question

我在使用 activeMQ 作为 JMS 提供者来运行我的 spring jms 项目时遇到了麻烦。出现错误：

线程“main”中的异常 org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法定位 Spring N 用于 XML 模式命名空间的 amespaceHandler [http://activemq.apache.org/schema/core] 违规资源：类路径资源[spring.xml]

非常感谢任何建议。代码如下：

Answer 1

需要验证的一些事情：

如果你使用 maven：执行全新安装

如果您使用爆炸的库创建战争，这可能是问题所在，因为它会覆盖 amq 和 spring 的配置、服务、xsd 文件...

你能否发布 libs 文件夹的 pom.xml 和 war 结构并确认你是否使用了 war 爆炸。

或者像这样改变你的定义：

<?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:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context"   
    xmlns:jms="http://www.springframework.org/schema/jms"
    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.xsd
        http://www.springframework.org/schema/jms 
        http://www.springframework.org/schema/jms/spring-jms.xsd">

  <bean id="mqConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">           
        <property  name="brokerURL" value="tcp://Toshiba:61616" />  
  </bean>

  <bean id="topic1" class="org.apache.activemq.command.ActiveMQTopic">
        <property name="physicalName" value="chattopic" />      
  </bean>

Answer 2

更新

lib 文件夹结构

我没有使用maven。
