Hard code获取Spring中Bean的几种方法

方法一:(通过FileSystemXmlApplicationContext)

通过程序在初始化的时候,导入Bean配置文件applicationContext.xml

ApplicationContext   ctx=new   FileSystemXmlApplicationConte( "classpath:applicationContext.xml");

BaseDAO   baseDAO=(BaseDAO)   ctx.getBean( "baseDAO ");

方法二:(通过WebApplicationContextUtil)

web.xml配置了applicationContext.xml自动加载

ApplicationContext ctx =  WebApplicationContextUtils.getWebApplicationContex(request.getSession().getServletContext());
BaseAction   baseAction=(BaseAction)   ctx.getBean( "baseAction ");


方法三:(通过ContextLoaderListener)

web.xml配置了applicationContext.xml自动加载

WebApplicationContext context = ContextLoaderListener.getCurrentWebApplicationContext();

BaseDelegate baseDelegate = (BaseDelegate) context.getBean("baseDelegate");
