Spring加載上下文幾種方式（Spring配置XML）

1:spring-mvc.xml中用import引入其他的配置文件
  <import resource="user_spring.xml" />

2：在web.xml配置，應用服務去加載
  <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>/WEB-INF/applicationContext*.xml,/WEB-INF/user_spring*.xml</param-value>
  </context-param>

3：引用資源用XmlBeanFactory（不能實現多個文件相互引用）

　　Resource resource = new ClassPathResource("appcontext.xml");
　　BeanFactory factory = new XmlBeanFactory(resource);

4：引用應用上下文用ClassPathXmlApplicationContext
　　ApplicationContext factory=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
　　ApplicationContext factory=new ClassPathXmlApplicationContext("conf/userConfig.xml");   
　　ApplicationContext factory=new ClassPathXmlApplicationContext("file:G:/Test/src/appcontext.xml");

5：用文件系統的路徑引用應用上下文用FileSystemXmlApplicationContext
　　ApplicationContext factory=new FileSystemXmlApplicationContext("src/applicationContext.xml");
　　ApplicationContext factory=new FileSystemXmlApplicationContext("classpath:appcontext.xml");
　　ApplicationContext factory=new FileSystemXmlApplicationContext("file:G:/Test/src/appcontext.xml");
　　ApplicationContext factory=new FileSystemXmlApplicationContext("G:/Test/src/appcontext.xml");

6：Web工程定制的加載方法 XmlWebApplicationContext
　　ServletContext servletContext = request.getSession().getServletContext();
　　ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext );
