In-Depth Information
resolver to identify which view should be returned to the user. In this case, the
BookController
returns a
ModelAndView
object named
bookList
. The fragment of the view resolver in
bookstore-servlet.xml
(from Listing 5-41) is shown here:
17. <beans:bean
18. class="org.springframework.web.servlet.view.InternalResourceViewResolver">
19. <beans:property name="prefix" value="/WEB-INF/views/" />
20. <beans:property name="suffix" value=".jsp" />
21. </beans:bean>
Based on the definition, the view resolver finds the file using the following mechanism:
Prefix + ModelAndView name + suffix, which translates to : /WEB-INF/jsp/bookList.jsp
ModelAndView.addObject("bookList", bookService.getBookList())
adds the book data returned by
getBookList()
to the model named
bookList
, which is formatted and rendered by the view.
Finally, the servlet engine renders the response via the specified JSP illustrated in Listing 5-43.
Listing 5-43. View
1. <%@page contentType="text/html" pageEncoding="UTF-8"%>
2. <%@ taglib prefix="c" uri="
