You are using an XML namespace (in this case context) without declaring it
您正在使用 XML 命名空间（在本例中为上下文）而不声明它
Change your xml to this:
将您的 xml 更改为：
<?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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd">
You were also referencing http://www.springframework.org/schema/beans/spring-beans-4.0.xsd, which I don't think exists.
您还引用了http://www.springframework.org/schema/beans/spring-beans-4.0.xsd，我认为它不存在。

Take attention: when you use contextnamespace, you should update in XML head 2attributes:
注意：当你使用context命名空间时，你应该在 XML head 2属性中更新：
xmlns:contextxsi:schemaLocation.
xmlns:contextxsi:schemaLocation.
Beginners used to add only xmlns:contextand forget about 2 new entries to xsi:schemaLocation:
初学者过去常常只添加xmlns:context而忘记了 2 个新条目xsi:schemaLocation：
<beans xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd"

If using Spring 4.0, here's what I found:
如果使用 Spring 4.0，这是我发现的：
<?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/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd"
xmlns:context="http://www.springframework.org/schema/context">
It worked for me. Found the reference here: http://javahash.com/spring-4-mvc-hello-world-tutorial-full-example/
它对我有用。在这里找到参考：http: //javahash.com/spring-4-mvc-hello-world-tutorial-full-example/
