Beans. Factory. beandefinitionstoreexception is caused by beans. Factory. So what is it? In the spring configuration file, that is, the configuration file beans you want to load, the object found is empty,

Common Errors:

Inconsistent spring versions, such as spring2.0 and 3.0

Example:

When xfire is added to spring2.0 (myeclipse), the following error occurs:
Document root element "beans", must match doctype root "null ".
Cause: spring1.2.6 conflicts with spring 2 in xfire core Lib!

<? XML version = "1.0" encoding = "UTF-8"?>
<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-2.0.xsd>
</Beans>

Spring 1.x uses doctype, while 2.x uses schema
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-2.0.xsd>
Delete, change
<? XML version = "1.0" encoding = "UTF-8"?>
<! Doctype beans public "-// spring // DTD bean // en" "http://www.springframework.org/dtd/spring-beans.dtd">
<Beans> </beans>

We often need to select a version when adding spring support to myeclipse. Later, we used spring web projects in the eclipse tool and didn't want to install myeclipse. This problem was encountered, but it was not very difficult.

 

Continue to practice. Use eclipse to learn things and install the required plug-ins. I think the learning is clearer and the entire process is clearer. I suggest you.

Of course, myeclipse is used for comparison. If there are ready-made tools, you can use them directly!
