classpath带星号*和不带星号的区别

classpath 和 classpath* 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.
spring web.xml里面加载applicationContext*.xml文件可以这样写，假如这些文件都是放在classes下：

<context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath:applicationContext-01-ds.xml
    classpath:applicationContext-02-hibernate.xml
    classpath:applicationContext-03-service.xml
    classpath:/*/applicationContext-*.xml
    classpath:/**/applicationContext-*.xml
 </param-value>
</context-param>
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
