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

Question

I'm trying to set up a simple spring application and I'm getting the below exception. This is being run standalone in eclipse indigo.

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)

Here's the initial portion of my code:

public static void main(String[] args) {

        try {

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


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

Here's my context.xml file:

<?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>

Answer 1

Are you sure you have spring-beans on the classpath?

This error normally means that it can't find a spring.schemas (which is in spring-beans.jar ) explaining to it what that namespace means.

Other options are that the Maven Shade plugin has damaged spring.schemas , but that's unlikely to be the case as you haven't mentioned Maven.

Answer 2

Maybe this post can help you:

Cannot find the declaration of element 'beans' in internet offline mode

It seems like being a problem of Schema configuration.

Answer 3

maven shade插件似乎取代了jar中的spring.schemas文件，因此使用每个jar中的所有单独的spring.schema内容创建我们自己的一个应该可以解决问题。

Answer 4

当我在STS中遇到这个问题时，我刚刚清理了项目并且它有效。

Answer 5

There could be possibility of mismatch of Spring Bean version and xsd definition.

For Example beans xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd

While in spring version is 3.0.5-Release

Check classpath version and keep them same. Shoul
