Unable to locate Spring NamespaceHandler for XML s

问题:

Any ideas, what could cause this error?

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/data/jpa] Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]

Here is my 'servle-context.xml' (there are some problems with the indents, but the file is too huge...):

As you can see, i specified the path to the jpa-schema. And I don't know what is the problem

回答1:

Try to replace

http://www.springframework.org/schema/data/jpa/spring-jpa.xsd

by

http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd

But if you still use Version 1.0-M1 then try to update first. DATAJPA-21

回答2:

Make sure you have spring-data-jpa in your dependencies

If you use maven:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.7.0.RELEASE</version>
</dependency>

回答3:

I fixed this by resolving the missing the spring-tx dependency in our project.

org.springframework:spring-tx

回答4:

The issue is because the spring-jpa schema cannot be located . You might be having some old jar which does not contain the schema info .

回答5:

I know this seems silly, but if you are using IDEA and Maven you should check to make sure you have Use plugin registry checked so that the server also has access to your jar files.

I would post a screen shot but I'm new on here and don't have enough reputation points. It does work though and I've verified with the support team at IntelliJ

After facing this same problem over a week, I found a solution. If you are using Spring MVC + JPA + Maven, use this dispatcher-servlet.xml

<?xml version="1.0" encoding="windows-1252"?>

</beans>

too late, but this solved my problem:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.9.4.RELEASE</version>
</dependency>
