java - 找不到元素“bean”的声明

Question

我有弹簧罐，spring-3.2.0.RC1.jar并试图从这里Apache ActiveMQ helloWorld给出的教程中实现程序。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>

主要的：

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**

我不知道豆子出了什么问题。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？

试试这个，假设你在 Spring 3.1：

<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">

用您使用的主要Spring 版本替换3.1最后一行。含义：即使有 Spring 版本，也没有XSD 。3.1.13.1.1

在解决我的问题的另一个线程上找到它......正在使用互联网连接较少的网络。

在这种情况下，从 url 复制 xsd 文件并将其放在 beans.xml 文件旁边并更改 xsi:schemaLocation 如下：

 <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

此错误找不到元素“bean”的声明，但出于完全不同的原因

原来我的互联网连接不是很可靠，所以我决定先检查这个网址

http://www.springframework.org/schema/context/spring-context-4.0.xsd

一旦我看到 xsd 成功打开，我清理了 Eclipse(IDE) 项目并且错误消失了

如果您尝试此步骤但仍然收到错误，请检查 Spring 版本，使其与另一个答案中提到的匹配

<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-**[MAYOR.MINOR]**.xsd">

将最后一行的 [MAYOR.MINOR] 替换为您正在使用的任何 major.minor Spring 版本

对于 Spring 4.0 http://www.springframework.org/schema/context/spring-context-4.0.xsd

对于 Sprint 3.1 http://www.springframework.org/schema/beans spring-beans-3.1.xsd

所有的上下文都在这里 http://www.springframework.org/schema/context/

我遇到了这个问题，根本原因是在 xsi:schemaLocation 中的 www.springframework.org/schema/beans 引用之后出现空白（如下图所示），即

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

确保构建路径中所有 spring jar 文件的版本与 xml 文件中提到的版本相同。

对我来说，问题是我的文件编码...我使用 powershell 编写 xml 文件，这不是 UTF-8 ...看来 spring 需要 UTF8，因为一旦我更改了编码（使用记事本++），它就会再次工作没有任何错误

现在我在我的powershellscript中使用以下行以UTF-8输出xml文件： [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)

而不是使用重定向运算符 > 来创建我的文件

注意：我没有在我的 beans 标记中放置任何 xml 参数，它可以工作

对我来说，问题是 spring 无法下载http://www.springframework.org/schema/beans/spring-beans.xsd或http://www.springframework.org/schema/context/spring-context。 xsd

但是我能够从我的浏览器访问那些，因为它正在使用我的机器代理。所以我只是将两个 xsd 的内容复制到名为 spring-beans.xsd 和 spring-context.xsd 的文件中，并用文件名替换了 http url，它对我有用。

我遇到了和你一样的情况。我的解决方案如下：

重新配置文件：Spring 配置文件（不使用 XSD 命名空间声明）。 -> 主要目的是没有标签名称（bean，...）
使用您要使用的类创建标签。 ---快乐编码---
