Spring5 MVC XmlViewResolver XML Configuration
Spring5 MVC XmlViewResolver XMLConfig Example

In this current lesson, we will write and execute example application for XmlViewResolver. We will also learn configuration of the XmlViewResolver in Spring5 MVC. As we discussed earlier about XmlViewResolver (click here), which allows us to configured the views in the XML.

Spring5 MVC XmlViewResolver XML Configuration

Configuration: We will learn about the configuration of XmlViewResolver here.

Please find the code snippet for controller.Here it is returning the string “home” as response.

Code snippet for HomeController.java

@Controller
public class HomeController {
	
	@RequestMapping(value="/getHelloMessage", method = RequestMethod.GET)
	public String getHelloMessage(ModelMap model) {
		
		model.addAttribute("msg", "Spring5 MVC XmlViewResolver XMLConfig Example !!");
		return "home";
		
	}
}

Code snippet for spring-dispatcher-servlet.xml

	<bean class="org.springframework.web.servlet.view.XmlViewResolver">
		<property name="location">
			<value>/WEB-INF/spring-views.xml</value>
		</property>
	</bean>

In the code snippet of spring-dispatcher-servlet.xml, we have configured XmlViewResolver as spring bean and configured property “location” with value “/WEB-INF/spring-views.xml”. Please find below given code snippet for spring-views.xml.

Code snippet of spring-dispatcher-servlet.xml

	<bean id="home" class="org.springframework.web.servlet.view.JstlView">
		<property name="url" value="/WEB-INF/views/home.jsp" />
	</bean>

If you observe, JstlView bean id in spring-views.xml and the return value in HomeController are same. So resulted view is home.jsp where html template will be prepared.

Please create web.xml and spring-dispatcher-servlet.xml as given below under WEB-INF directory.

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0">
  <display-name>Basic Example for Spring5 MVC</display-name>
  <servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

spring-dispatcher-servlet.xml

<beans xmlns = "http://www.springframework.org/schema/beans"
   xmlns:context = "http://www.springframework.org/schema/context"
   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation = "http://www.springframework.org/schema/beans     
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context.xsd">

  	<bean class="org.springframework.web.servlet.view.XmlViewResolver">
		<property name="location">
			<value>/WEB-INF/spring-views.xml</value>
		</property>
	</bean>
	<context:component-scan base-package="com.docsconsole.tutorials.springmvc5.*" />

</beans>

To handle the request, we need to write the one Controller class. Please write code for HomeController.java as given below.

HomeController.java

package com.docsconsole.tutorials.springmvc5.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HomeController {

	@RequestMapping(value = "/getHelloMessage", method = RequestMethod.GET)
	public String getHelloMessage(ModelMap model) {

		model.addAttribute("msg", "Spring5 MVC XmlViewResolver XMLConfig Example !!");
		return "home";

	}
}

To display results as view we need to create home.jsp. Please find below given code snippets for the same.

home.jsp

<%@ page contentType = "text/html; charset = UTF-8" %>
<html>
   <head>
      <title>Spring5-MVC-XmlViewResolver-XMLConfig-Example</title>
   </head>
   
   <body>
      <h2 style="color: #528396;padding: 20 0 0 40;">${msg}</h2>
   </body>
</html>

spring-views.xml is the xml where we can configure the views in this xml.

spring-views.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
		http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">


	<bean id="home" class="org.springframework.web.servlet.view.JstlView">
		<property name="url" value="/WEB-INF/views/home.jsp" />
	</bean>
</beans>

Please find the below given screenshot for final project architecture.

We will create war by using maven and then will deploy the war in tomcat server. When we fire the URL “http://localhost:8080/Spring5-MVC-XmlViewResolver-XMLConfig-Example/getHelloMessage” then we can see below given output.

Please refer to the Github repository here Spring5-MVC-XmlViewResolver-XML-Example-App
