2.静态工厂注入：
修改beans.xml:

<bean name="userDomain" class="com.linying.domain.User"></bean>
<bean name="userAction" class="com.linying.service.UserAction">
<property name="user" ref="userDomain"></property>
<property name="userDao" ref="userDao"></property>
</bean>
增加工厂：
package com.linying.factory;
import com.linying.dao.UserDao;
/**
* Dao静态工厂
* @author Ying-er
* @time 2010-6-20 下午04:23:25

public static UserDao getUserDao(){

}
}
控制台输出：
UserDao构造
User构造
UserAction构造
setUser方法被调用
setUserDao方法被调用
执行insert方法
saveUser方法被调用
3.实例工厂注入：
修改beans.xml：
<bean name="daoFactory" class="com.linying.factory.DaoFactory"></bean>
<bean name="userDao" factory-bean="daoFactory" factory-method="getUserDao"></bean>
<bean name="userDomain" class="com.linying.domain.User"></bean>
<bean name="userAction" class="com.linying.service.UserAction">
<property name="user" ref="userDomain"></property>
<property name="userDao" ref="userDao"></property>

public UserDao getUserDao(){
return new UserDao();
}
}
控制台输出：
UserDao构造
User构造
UserAction构造
setUser方法被调用
setUserDao方法被调用
执行insert方法
saveUser方法被调用
4.构造器注入：
修改beans.xml:
<bean name="userDao" class="com.linying.dao.UserDao"></bean>
<bean name="userDomain" class="com.linying.domain.User"></bean>
<bean name="userAction" class="com.linying.service.UserAction">
<constructor-arg ref="userDomain"></constructor-arg>
<constructor-arg ref="userDao"></constructor-arg>
</bean>
修改UserAction.java:
package com.linying.service;
import com.linying.dao.UserDao;
import com.linying.domain.User;
/**
* UserAction

this.userDao = userDao;
}
/**
* 保存User对象

*/
public void saveUser() {

System.out.println("saveUser方法被调用");
}
// public void setUser(User user) {
// this.user = user;
// System.out.println("setUser方法被调用");
// }
//
// public void setUserDao(UserDao userDao) {
// this.userDao = userDao;
// System.out.println("setUserDao方法被调用");
// }
}
控制台输出：
UserDao构造
User构造
UserAction构造(有参构造)
执行insert方法
saveUser方法被调用
5.集合注入：
