<bean id="userAction" class="com.umgsai.spring.UserAction" scope="singleton"/>

<bean id="userManager" class="com.umgsai.spring.UserManager" scope="prototype">
<property name="username" value="root">
</property>
<property name="password" value="123456">
</property>
<property name="url" value="jdbc:mysql://localhost:8080/3305">

</property>
</bean>

</beans>

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
