Spring 获取bean
方法一:
ApplicationContext ap = new ClassPathXmlApplicationContext("applicationContext.xml");
在applicationContent.xml中配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" 4 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 5 //中间部分是你自己配置的所有bean
WEB项目:
方法1:
ApplicationContext ac1 = WebApplicationContextUtils.getRequiredWebApplicationContext(ServletContext sc)
方法2:
ApplicationContext ac2 = WebApplicationContextUtils.getWebApplicationContext(ServletContext sc)
方法3:
写一个工具类类继承ApplicationObjectSupport,并将这个加入到spring的容器
方法4:
写一个工具类类继承WebApplicationObjectSupport,并将这个加入到spring的容器
方法1、2中使用ac.getBean("beanid");获取实例
