spring配置

1：当context中有重复的bean id时抛出异常
//XmlWebApplicationContext context = (XmlWebApplicationContext) applicationContext; 
ClassPathXmlApplicationContext classPathAppCtx = new ClassPathXmlApplicationContext(new String[] { this.uri }, false);
//设置allowBeanDefinitionOverriding属性为false 
context.setAllowBeanDefinitionOverriding(false);
