I have the spring jars of spring-3.2.0.RC1.jar and trying to implement Apache ActiveMQ helloWorld program from tutorial given here. The xml configuration file is:
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<beans xmlns:jms=\"http://www.springframework.org/schema/jms\"

ApplicationContext context = new FileSystemXmlApplicationContext(\"src/com/jms/helloworld/config/JMSConfig.xml\");

I don\'t know what is wrong with the beans.So far any suggestion in other question doesn\'t help. Any help?
回答1:
Try this, assuming you're on 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">
Replace 3.1 on the last line with whatever major Spring version you use. Meaning: there is no 3.1.1 XSD even though there is a Spring version 3.1.1.
回答2:
Found it on another thread that solved my problem... was using an internet connection less network.
In that case copy the xsd files from the url and place it next to the beans.xml file and change the xsi:schemaLocation as under:
<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">
回答3:
This error of Cannot find the declaration of element 'beans' but for a whole different reason
It turs out my internet connection was not very reliable, so i decided to check first for this url
http://www.springframework.org/schema/context/spring-context-4.0.xsd
Once I saw that the xsd was open succesfully I clean the Eclipse(IDE) project and the error was gone
If you try this steps and still get the error then check the Spring version so that it matches as mentioned by another answer
<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">
Replace [MAYOR.MINOR] on the last line with whatever major.minor Spring version that you are using
For Spring 4.0 http://www.springframework.org/schema/context/spring-context-4.0.xsd
For Sprint 3.1 http://www.springframework.org/schema/beans spring-beans-3.1.xsd
All the contexts are available here http://www.springframework.org/schema/context/

Add this code ..It helped me
<?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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
classpath:/org/springframework/beans/factory/xml/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
classpath:/org/springframework/context/config/spring-context-3.0.xsd
http://www.springframework.org/schema/aop
classpath:/org/springframework/aop/config/spring-aop-3.0.xsd
">
</beans>
回答5:
I had this issue and the root cause turned out to be white-space (shown as dots below) after the www.springframework.org/schema/beans reference in xsi:schemaLocation, i.e.
<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"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans....
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
回答6:
Try Using this- Spring 4.0. Working
<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">
回答7:
Make sure if all the spring jar file's version in your build path and the version mentioned in the xml file are same.

Use this to solve your problem:
<context:annotation-config/>
