使用spring获取错误消息"cvc-elt.1:找不到元素'beans'的声明."

Question

我正在尝试设置一个简单的spring应用程序,我得到以下异常.这是在eclipse indigo中独立运行的.

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Line 2 in XML document from class path resource [context.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'beans'.
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'beans'.
      at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:195)
      at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.error(ErrorHandlerWrapper.java:131)
      at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:384)
      at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:318)

这是我的代码的初始部分:

public static void main(String[] args) {

        try {

            BeanFactory beanfactory = new ClassPathXmlApplicationContext(
                    "context.xml");


            FirstBean bean = (FirstBean) beanfactory.getBean("show");

这是我的context.xml文件:

<?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:aop="http://www.springframework.org/schema/aop"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="anotherBean" class="AnotherBean" />
<bean id="show" class="FirstBean">
<constructor-arg ref="anotherBean" />
</bean>
<bean id="populateFD" class="PopulateFactData">
<constructor-arg value="localhost" />
<constructor-arg value="3309" />
</bean>
</beans>

你确定你有spring-beans类路径吗？

此错误通常意味着它无法找到spring.schemas(正在spring-beans.jar)向其解释该命名空间的含义.

其他选择是Maven Shade插件已损坏spring.schemas,但由于你没有提到Maven,情况不太可能如此.
