找不到元素’beans’的声明
我有spring-3.2.0.RC1.jar的spring jar，并尝试从这里给出的教程实现Apache ActiveMQ helloWorld程序。 xml配置文件是：
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 No appenders could be found for logger (org.springframework.core.env.StandardEnvironment). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

我不知道豆子有什么问题。到目前为止，在其他问题上的任何建议都无济于事。 有帮助吗？
试试这个，假设您使用的是Spring 3.1：
用你使用的主要 Spring版本替换最后一行的3.1 。 含义：即使有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减少网络。
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：
这个错误无法找到元素’beans’的声明，但出于完全不同的原因
它让我的互联网连接不太可靠，所以我决定先检查这个url
http://www.springframework.org/schema/context/spring-context-4.0.xsd
一旦我看到xsd成功打开，我就清理了Eclipse（IDE）项目，错误消失了
如果你尝试这个步骤仍然得到错误，那么检查Spring版本，使其匹配另一个答案所提到的
用你正在使用的任何major.minor Spring版本替换最后一行的[MAYOR.MINOR]
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
所有上下文都可以在这里找到http://www.springframework.org/schema/context/
添加此代码..它帮助了我
在xsi：schemaLocation中的www.springframework.org/schema/beans引用之后，我遇到了这个问题并且根本原因是白色空间（如下面的点所示），即
尝试使用这个 – Spring 4.0。 加工
用它来解决你的问题：
