写一个方法
public void setProperty(Object obj,String propertyName,Object value){}
此方法可以将obj对象中名为propertyName的属性值设置为value


public class Tool {
        public void setProperty(Object obj, String propertyName, Object value) throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException{
                Class c = obj.getClass();               
                Field field = c.getDeclaredField(propertyName);
                field.setAccessible(true);
                field.set(obj, value);               
        }
}
