找不到元素'beans'的声明

标签: java spring activemq message-queue

我有spring-3.2.0.RC1.jar的弹簧罐,并试图从给定here的教程中实施Apache ActiveMQ helloWorld程序。 xml配置文件是:

<?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**

我不知道豆子有什么问题。到目前为止,其他问题的任何建议都无济于事。有什么帮助吗?

试试这个,假设您使用的是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">

使用您使用的主要 Spring版本替换最后一行的3.1。含义:即使存在Spring版本3.1.1,也没有3.1.1 XSD。

在另一个解决了我的问题的线程上找到它...正在使用互联网连接而不是网络。

在这种情况下,从URL中复制xsd文件并将其放在beans.xml文件旁边,并将xsi:schemaLocation更改为:

 <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 
spring-beans-3.1.xsd">

此错误无法找到元素&bean的声明&#39;但出于完全不同的原因

我的互联网连接不太可靠,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,我就清理Eclipse(IDE)项目并且错误消失了

如果您尝试此步骤仍然会收到错误 检查Spring版本,以便它与另一个答案中提到的匹配

Stored Procedure

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 弹簧豆-3.1.xsd

此处提供所有上下文 http://www.springframework.org/schema/context/

添加此代码..它帮助了我

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"

我遇到了这个问题,在xsi:schemaLocation中的www.springframework.org/schema/beans引用之后,根本原因被证明是白色空间(如下图所示),即

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="tests.globalactivitytest"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="23" />

    <application
        android:name=".activity.GlobalActivity"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".LaunchOnceActivity"
            android:label="@string/title_activity_launch_once" >
        </activity>
    </application>

</manifest>

尝试使用这个 - Spring 4.0。工作

<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" 
       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">

请确保您的构建路径中所有spring jar文件的版本与xml文件中提到的版本是否相同。

答案 7 :(得分:0)

对我来说,问题是我的文件编码...我使用powershell编写xml文件,但这不是UTF-8 ... 春天似乎需要UTF8,因为一旦我更改了编码(使用notepad ++),它就可以再次正常运行而没有任何错误

现在我在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)

代替使用重定向运算符>创建我的文件

注意:我没有在Beans标记中放入任何xml参数,并且可以正常工作

答案 8 :(得分:0)

对我来说,问题在于spring无法下载http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context/spring-context.xsd

但是,我可以使用我的机器代理从浏览器访问那些文件。因此,我只是将两个xsds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:

  1. 重新配置文件:Spring 配置文件(不使用 XSD 命名空间声明)。 2. -> 主要目的是没有标签名(bean, ...)
  2. 使用您要使用的类创建标签。 enter image description here ---HappyCoding---
