错误中是因为找不到"beans"导致的。

### 错误原因 ###

<?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/context http://www.springframework.org/schema/context/spring-context.xsd">
    
      
    
    </beans>

原因是因为：

xsi:schemaLocation=""

中没有引入beans的命名空间：

### 错误解决方案 ###

只需要在 `xsi:schemaLocation` 中增加如下地址即可：

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd "

完整的头部：

<?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">
    						
    </beans>
