You're schemaLocationvalue should be of the form
你的schemaLocation价值应该是这样的
namespace-name schema-location [namespace-name schema-location]
You're missing
你不见了
http://www.springframework.org/schema/context
before
前
http://www.springframework.org/schema/context/spring-context-3.1.xsd
It should therefore be
因此应该是
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd">
Note that I've changed the utilschema to version 3.1. Don't mix and match. Use all the same versions.
请注意，我已将util架构更改为3.1 版。不要混搭。使用所有相同的版本。

SchemaLocation must be in the form of namespace-name schema-location [namespace-name schema-location]
SchemaLocation 必须采用 namespace-name schema-location [namespace-name schema-location] 的形式
like example
喜欢的例子
xmlns:mytag="http://www.brajesh.com/tagsDef"
xsi:schemaLocation="http://www.brajesh.com/tagsDef
http://www.brajesh.com/tagsDef.xsd"
Here we are conveying to xml that, we are going to use my custom tag that is 'mytag' which is defined in http://www.brajesh.com/tagsDefname-space location.
You can validate these tags from http://www.brajesh.com/tagsDef.xsdlocation for http://www.brajesh.com/tagsDef.
Due to this reason, schema location must have even URLs.
在这里，我们向 xml 传达了这一点，我们将使用我的自定义标签，即在http://www.brajesh.com/tagsDef名称空间位置定义的“mytag” 。您可以从http://www.brajesh.com/tagsDef.xsd位置验证这些标签http://www.brajesh.com/tagsDef。由于这个原因，模式位置必须有偶数的 URL。
