我看到了这个：
public static <T,U extends T> AutoBean<T> getAutoBean(U delegate)
我知道输入类是U类型，而AutoBean类是T类型，而U扩展T是边界。但是，这<T,是什么意思呢？
Also, if I am going to write a function to accept the output of getAutoBean, how would you write the function declaration? (i.e. myFunction(getAutoBean(...)), what will the function declaration of myFunction() be?)
Thank you!
