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>
