java - <beans :beans> and <beans> 是什么意思

Question

有什么区别

<beans xmlns="http://www.springframework.org/schema/beans"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
xmlns:p="http://www.springframework.org/schema/p"  
xmlns:context="http://www.springframework.org/schema/context"  
xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">  

和

<beans:beans xmlns="http://www.springframework.org/schema/beans"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
xmlns:p="http://www.springframework.org/schema/p"  
xmlns:context="http://www.springframework.org/schema/context"  
xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

您能解释一下这两者之间有什么区别吗？

Answer 1

它是一个 XML 命名空间，用于分隔可能存在冲突的元素名称，因此没有真正的区别。
