applicationContext.xml

package com.umgsai.spring;import javax.annotation.Resource;import org.springframework.beans.BeansException;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.BeanFactoryAware;public class UserAction implements BeanFactoryAware{    @Resource//省略set方法    private UserManager userManager = null;    public UserAction(UserManager userManager){        super();        this.userManager = userManager;    }                     public UserAction(){        super();    }                     public String execute() {        User user = new User();        //userManager = (UserManager)factory.getBean("manager");        userManager.add(user);        System.out.println("userManager:"+userManager);                             return "success";    }    private BeanFactory factory = null;    public void setBeanFactory(BeanFactory factory) throws BeansException {        this.factory = factory;        }}

测试

BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");UserAction userAction = (UserAction)factory.getBean("userAction");System.out.println(userAction.execute());

执行结果

root

123456

jdbc.mysql.Driver

jdbc:mysql://localhost:8080/3305

添加User操作

userManager:com.umgsai.spring.UserManager@177ba38f

success
