web.xml中classpath:和classpath*:  有什么区别?  
 
classpath：只会到你的class路径中查找找文件;  
classpath*：不仅包含class路径，还包括jar文件中(class路径)进行查找. 
 
  
 
存放位置： 
1：src下面 
需要在web.xml中定义如下： 

<context-param>  
<param-name>contextConfigLocation</param-name>  
<param-value>classpath:applicationContext.xml</param-value>  
< /context-param>

 
 
2：WEB-INF下面 
需要在web.xml中定义如下： 

<context-param>  
<param-name>contextConfigLocation</param-name>  
<param-value>WEB-INF/applicationContext*.xml</param-value>  
< /context-param>

 
 
web.xml 通过contextConfigLocation配置spring 的方式  
SSI框架配置文件路径问题：  
 
struts2的 1个+N个 路径：src+src(可配置) 名称： struts.xml + N  
spring 的 1个 路径： src 名称： applicationContext.xml 
ibatis 的 1个+N个 路径： src+src(可配置) 名称： SqlMapConfig.xml + N  
 
 
部署到tomcat后，src目录下的配置文件会和class文件一样，自动copy到应用的 classes目录下  
 
spring的 配置文件在启动时，加载的是web-info目录下的applicationContext.xml,  
运行时使用的是web-info/classes目录下的applicationContext.xml。  
 
配置web.xml使这2个路径一致：  

<context-param>   
<param-name>contextConfigLocation</param-name>   
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>   
< /context-param>

  
 
多个配置文件的加载  

<context-param>   
<param-name>contextConfigLocation</param-name>   
<param-value>   
classpath*:conf/spring/applicationContext_core*.xml,   
classpath*:conf/spring/applicationContext_dict*.xml,   
classpath*:conf/spring/applicationContext_hibernate.xml,   
classpath*:conf/spring/applicationContext_staff*.xml,   
classpath*:conf/spring/applicationContext_security.xml   
classpath*:conf/spring/applicationContext_modules*.xml   
classpath*:conf/spring/applicationContext_cti*.xml   
classpath*:conf/spring/applicationContext_apm*.xml   
</param-value>   
</context-param>

contextConfigLocation 参数定义了要装入的 Spring 配置文件。  
 
首先与Spring相关的配置文件必须要以"applicationContext-"开头，要符合约定优于配置的思想，这样在效率上和出错率上都要好很多。  
还有最好把所有Spring配置文件都放在一个统一的目录下，如果项目大了还可以在该目录下分模块建目录。这样程序看起来不会很乱。  
在web.xml中的配置如下：  
Xml代码  

<context-param>   
< param-name>contextConfigLocation</param-name>   
< param-value>classpath*:**/applicationContext-*.xml</param-value>   
< /context-param>

  
 
"**/"表示的是任意目录；  
"**/applicationContext-*.xml"表示任意目录下的以"applicationContext-"开头的XML文件。  
你自己可以根据需要修改。最好把所有Spring配置文件都放在一个统一的目录下，如：  
 
<!-- Spring 的配置 -->  

<context-param>   
<param-name>contextConfigLocation</param-name>   
<param-value>classpath:/spring/applicationContext-*.xml</param-value>   
< /context-param>
