In a servlet container that's considered non-JAX-RS aware, the Application subclass name should be supplied as an init-param within the servlet definition.
在一个被认为是不能感知JAX - RS的servlet容器内，应该作为servlet定义内的init - param提供application子类名。
The RestServlet is passed as init-param the name of the Application subclass that the Book service supplies.
RestServlet被传递为init - param，这是Books服务提供的application子类的名称。
