请教下,spring中如何实例化这个bean

Question

我有这样一个方法

package mytest;

public class TestImpl extends AbstractTest implements TestIfc{

public void handler() {
    // TODO Auto-generated method stub      
}

@Override
public void test() {
    // TODO Auto-generated method stub      
}


}

public abstract class AbstractTest {

public abstract void test();


}

public interface TestIfc {

public void hander();


}

spring配置文件

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                ">

&lt;bean id="test" class="mytest.TestImpl" 

&gt;


</beans>

谢谢各位。



问题补充



我使用

ClassPathXmlApplicationContext c = new ClassPathXmlApplicationContext("application.xml");

TestImpl test = (TestImpl)c.getBean(test);

会有  java.lang.ClassCastException 

spring默认使用的是jdk的动态代理 ,必须要以下操作才可以

TestIfc test = (TestIfc)c.getBean(test);

使用这个获取到bean不会有问题,但这样我就无法调用 方法 test() 了。

[quote]public abstract class AbstractTest {

public abstract void test();   

} [/quote]

没存在的必要; 面向接口;才是该做的.
