UserAction.java

package com.umgsai.spring;
public class UserAction {
    private UserManager userManager;
    public void setUserManager(UserManager userManager) {
        this.userManager = userManager;
    }
    public String execute() {
        User user = new User();
        userManager.add(user);
        return "success";
    }
}

public static void main(String[] args) {
    //IMessage message = MessageFactory.create("1");
    //创建spring Bean工厂
    BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");
    //BeanFactory factory = new ClassPathXmlApplicationContext("app*.xml");通配符
    UserAction userAction = (UserAction)factory.getBean("userAction");
    System.out.println(userAction.execute());
}
