setMethod.invoke(bean,zhangsan);

<bean id="id" class="com.spring.User">

<constructor index="1" value="20" />

....

</bean>

Class targetClass = Class.forName("com.spring.User");

Constructor targetCtr = targetClass.getConstructor(zhangsan.getClass(),20.getClass());

Object bean = targetCtr.newInstance("zhangsan","20");
