Below is the error I am getting.
下面是我得到的错误。

I am also getting "The fully qualified name of the bean's class, except if it serves only as a parent definition for child bean definitions." when I hover my mouse over class="org.apache.commons.dbcp.BasicDataSource" What does it mean?
我还收到“bean 类的完全限定名称，除非它仅用作子 bean 定义的父定义。” 当我将鼠标悬停在 class="org.apache.commons.dbcp.BasicDataSource" 上时，这是什么意思？
Could someone help me resolve the issue. I am trying to work on a simple spring hibernate and mysql. Thanks.
有人可以帮我解决这个问题。我正在尝试使用简单的 spring 休眠和 mysql。谢谢。

Also adding this dependency to pom.xml worked for me :)
还将此依赖项添加到 pom.xml 对我有用:)
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>

I think your error is more related to the fact that you are using an XML namespace without declaring it.
我认为您的错误与您使用 XML 命名空间而不声明它的事实更相关。
As explainted in this answer. Try to add http://www.springframework.org/schema/context/spring-context.xsdto the schemaLocation:
如本答案所述。尝试添加http://www.springframework.org/schema/context/spring-context.xsd到 schemaLocation：
<?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"
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">
