spring---------配置文件的命名空间

浏览数：20 / 时间：2015年06月08日

两种格式的配置文件：

DTD和Schema区别：http://www.cnblogs.com/zhaozhan/archive/2010/01/04/1639194.html

1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"　　<!--默认命名空间：表示未使用其他命名空间的所有标签的默认命名空间-->
3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"　　 <!--xsi标准命名空间，用于指定义自定义命名空间的schema文件，声明后就可以使用 schemaLocation 属性了-->
4     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">　　<!--此处可以不配置，可以用来引用schema在本地的副本-->
5 　　 
6     
7 
8 </beans>

为每个命名空间指定了对应的Schema文档的时候，定义的语法为：

　　“全称命名空间1 空格全称命名空间1对应的Schema文件空格”

其他命名空间与

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

同一级别下配置即可

util

util标签用来处理公用、实用的配置问题，例如配置集合、常量及诸如此类的东西

xmlns:util="http://www.springframework.org/schema/util"

xsi:schemaLocation中需要定义

http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd

jee标签用来处理javaee标准相关的问题，例如查询一个jndi对象以及定义一个ejb的引用等

xmlns:jee="http://www.springframework.org/schema/jee"

xsi:schemaLocation中需要定义

http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd

lang

lang用来将那些已经被定义在一些动态语言（例如Jruby和Groovy）中的对象作为beans中的对象存放到spring容器中

xmlns:lang="http://www.springframework.org/schema/lang"

xsi:schemaLocation中需要定义

http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang.xsd

xmlns:jms="http://www.springframework.org/schema/jms"

http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms.xsd

tx (transaction)

使用时建议配合aop

xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd

xmlns:aop="http://www.springframework.org/schema/aop"

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd

context

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

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

jdbc

xmlns:jdbc="http://www.springframework.org/schema/jdbc"

http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd

cache

xmlns:jdbc="http://www.springframework.org/schema/cache"

http://www.springframework.org/schema/cache http://www.springframework.org/schema/jdbc/spring-cache.xsd
