Chapter 10 ■ Showing Your Spring Application on the Web The DispatcherServlet defined in your web.xml, as shown in Listing 10-4, will be the front controller that is taking care of sending requests to the controller (see Listing 10-3) and the response back with the correct view. Now you need to tell the Spring MVC where your views will be. Listing 10-5 contains the Spring XML configuration needed for the Spring container to instantiate the necessary beans. Listing 10-5. mydocuments-servlet.xml select d.documentId, d.name, d.location, d.description as doc_desc, d.typeId, d.created, d.modified, t.name as type_name, t.description as type_desc, t.extension from documents d join types t on d.typeId = t.typeId 137
Chapter 10 ■ Showing Your Spring Application on the Web Do you see anything new in Listing 10-5? Yes, that’s right, the namespace. This namespace will help you to set up everything and get it ready for your MVC. Also, you need to add the tag. This tag will tell the Spring container to look for any annotated class with the @Controller annotation, so it knows the controller will be the delegate from the front controller (DispatcherServlet). Next, you need to specify what view engine you are going to use; in this case it will be the InternalResourceViewResolver with two properties. The first property will be the prefix where your web pages will live and the second property will be the suffix where it tells the Spring MVC that your views will be JSPX pages. ■ ■Note Your Spring context XML file needs to be named after the name of the servlet definition, followed by –servlet.xml, so the format will be -servlet.xml. In your case, you define your servlets as mydocuments, so the name of the XML file will be mydocuments-servlet.xml. This is one of the many standards we will use. Next, you need to add your JSPX file. JSPX is an XML variation of a JSP which is used to create dynamic web pages but using an XML syntax. This file will live in the WEB-INF/views/search/ folder and it will be named all.jspx. Listing 10-6 shows your view. Listing 10-6. all.jspx My Documents My Documents - Search Name: ${doc.name} Type: ${doc.type.name} 138
