1)配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<context-param>
  <param-name>contextConfigLocation</param-name>
     
  <param-value>
   WEB-INF/applicationContext*.xml
   classpath:applicationContext-datasource.xml
   classpath:applicationContext-hibernate.xml
   classpath:applicationContext-dao.xml
   classpath:applicationContext-service.xml
  </param-value>
</context-param>
<listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
</listener>
</web-app>

2)Jsp页面中调用spring
<%
org.springframework.beans.factory.BeanFactory beanFactory = (org.springframework.beans.factory.BeanFactory)
pageContext.getServletContext().getAttribute(org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);

%>
3)Servlet中调用spring

ServletContext context = this.getServletContext();
org.springframework.beans.factory.BeanFactory beanFactory = (org.springframework.beans.factory.BeanFactory)
context.getAttribute(org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);

4)ClassPath加载

ApplicationContext beanFactory = new ClassPathXmlApplicationContext(
    new String[] { "applicationContext-datasource.xml",
      "applicationContext-hibernate.xml",
      "applicationContext-service-freemarker.xml",
      "applicationContext-service.xml"

});
