in the book "spring in action", MVC chapter,
the example defines the view-resolver by declaring a bean
class="org.springframework.web.
➥ servlet.view.InternalResourceViewResolver">

/WEB-INF/jsp/

.jsp

but it does not attach the bean anywhere (for example as a property of
the servlet in web.xml )
so how does spring know that this bean is a view resolver? does it decide
that this implements ViewResolver so that it must use this bean for resolver
?? what if I declare multiple beans that implement resolver ?

他们不是都实现了view resolver了吗，Spirng大概从这里知道的！

Spring MVC uses a few default beans, all of them can be overwritten
in configuration. If you want to see the details, read the source
code.

Spring has quite a lot of autowire built-in. It will automatically detect
the defined bean in the required interface or class and use it if there is
no ambiguity.
