Spring Multiple View Page

The Spring-based web application, you can configure multiple view pages to display different content or templates using technologies like JSP (JavaServer Pages), Thymeleaf, or FreeMarker. These view pages are typically associated with Spring MVC controllers and can be used to present data to the user. Here’s how you can set up multiple view pages in a Spring web application:

1. Choose a View Technology:

Select a view technology for your Spring application. Common choices include JSP, Thymeleaf, and FreeMarker. In this example, we’ll use JSP.

2. Configure View Resolver:

Configure a view resolver in your Spring configuration to map logical view names to actual view files. For example, with JSP:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>

In this example, JSP views are expected to be located in the /WEB-INF/views/ directory with a .jsp extension.

3. Create View Pages:

Create your view pages (e.g., .jsp files) and place them in the configured directory. Each view page represents a specific view in your application.

For example, you might have two JSP files: home.jsp and about.jsp.

4. Create Spring MVC Controllers:

Create Spring MVC controllers to handle different requests and map them to specific view pages. For example:

@Controller
public class HomeController {
    @RequestMapping("/")
    public String home() {
        return "home"; // Maps to home.jsp
    }
}

@Controller
public class AboutController {
    @RequestMapping("/about")
    public String about() {
        return "about"; // Maps to about.jsp
    }
}

In this example, the HomeController maps the root URL (“/”) to the “home” view page, and the AboutController maps the “/about” URL to the “about” view page.

5. Access the View Pages:

When you access the corresponding URLs in your web browser, Spring will use the configured view resolver to locate and render the appropriate view page. For example:

• Accessing / will render home.jsp.
• Accessing /about will render about.jsp.

You can have as many view pages and controllers as needed to handle different parts of your application. This allows you to present various views to users, each with its own content and layout.

Remember to configure your Spring DispatcherServlet and other necessary components in your web application context XML file or Java configuration to enable Spring MVC functionality.
