?

1 2 3 4 5 6

<table>   <tr>     <td>Applestd>     <td>Bananastd>   tr> table>

    和描述一张桌子的

：

?

1 2 3 4 5

<table>   <name>African Coffee Tablename>   <width>80width>   <length>120length> table>

?

1	xmlns:context="http://www.springframework.org/schema/context"

?

1	<context:component-scan base-package="xxx.xxx.controller" />

?

1	xmlns:abc="namespaceURI"

?

1 2 3 4 5 6 7

<h:table xmlns:h="url1">   <h:tr>     <h:td>Applesh:td>     <h:td>Bananash:td>   h:tr> h:table>

?

1 2 3 4 5 6

<f:table xmlns:f="url2">   <f:name>African Coffee Tablef:name>   <f:width>80f:width>   <f:length>120f:length> f:table>

?

1	xmlns="http://www.springframework.org/schema/beans"

?

1 2 3

<bean id="xxx" class="xxx.xxx.xxx.Xxx">   <property name="xxx" value="xxxx"/> bean>

?

1	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

?

1 2	xsi:schemaLocation="http://www.springframework.org/schema/context                      http://www.springframework.org/schema/context/spring-context.xsd"

http://www.springframework.org/schema/context/spring-context.xsd。这里我们可以打开这个Schema的位置，下面是这个文档的开始部分：

?

1 2 3 4 5 6 7 8 9

<xsd:schema xmlns="http://www.springframework.org/schema/context"             xmlns:xsd="http://www.w3.org/2001/XMLSchema"             xmlns:beans="http://www.springframework.org/schema/beans"             xmlns:tool="http://www.springframework.org/schema/tool"                                         targetNamespace="http://www.springframework.org/schema/context"             elementFormDefault="qualified"             attributeFormDefault="unqualified">

 

    有了上面的说明后，再去理解开始的Spring XML文档，一定会有不一样的感觉！   

    最后再次感谢各位前辈的宝贵经验。
