java - 找不到元素 'beans' 的声明

Question

我有 spring-3.2.0.RC1.jar 的 spring jar 并尝试从给出的教程中实现 Apache ActiveMQ helloWorld 程序here . xml配置文件为:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns:jms="http://www.springframework.org/schema/jms"
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans"
    xsi:schemalocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/jms 
    http://www.springframework.org/schema/jms/spring-jms.xsd">

    <bean class="org.apache.activemq.command.ActiveMQQueue" id="destination">
        <constructor-arg value="TEST.Q1"></constructor-arg>
    </bean>

    <bean class="org.apache.activemq.ActiveMQConnectionFactory" id="connectionFactory"
        p:brokerurl="tcp://localhost:8161"></bean>

    <bean class="com.jms.helloworld.listner.MessageListenerImpl" id="simpleMessageListener">
        <bean
            class="org.springframework.jms.listener.DefaultMessageListenerContainer"
            id="jmsContainer">
            <property name="connectionFactory" ref="connectionFactory"></property>
            <property name="destination" ref="destination"></property>
            <property name="messageListener" ref="simpleMessageListener"></property>
        </bean>
    </bean>
</beans>    

主要:

public static void main(String[] args) throws JMSException {
        System.out.println("LISTNER STARTED");
        ApplicationContext context =  new FileSystemXmlApplicationContext("src/com/jms/helloworld/config/JMSConfig.xml");
    }

**Exception on console**


LISTNER STARTED

log4j:WARN Please initialize the log4j system properly.

我不知道 bean 出了什么问题。到目前为止，其他问题中的任何建议都无济于事。有什么帮助吗？

Answer 1

假设您使用的是 Spring 3.1，试试这个:

<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">

将最后一行的 3.1 替换为您使用的任何 主要 Spring 版本。含义:即使有Spring版本3.1.1，也没有3.1.1 XSD。
