Step 1: Create a maven project and choose the maven web project and give the group id and artifact id for your project.

Step 2: Add the web server to the project - right click the project and select properties -> select targeted runtimes and choose the server and click ok.

Step 3: Add a folder named "java" inside the folder src->main. Delete index.jsp file from your project.

step 4: Add the spring framework into the project by adding its depencies inside pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>5.0.8.RELEASE</version>
</dependency>  
    
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.0.8.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.0.8.RELEASE</version>
</dependency>

step 5: create a file named spring-config.xml, root-context.xml, web.xml inside the path src/main/webapp/WEB-INF

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

	<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
	
	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

	<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />
	
	
	<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
	<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/views/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<context:component-scan base-package="controller" />
	
</beans:beans>

root-context.xml
----------------

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	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">
	
	<!-- Root Context: defines shared resources visible to all other web components -->
		
</beans>

web.xml
-------

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

	<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/root-context.xml</param-value>
	</context-param>
	
	<!-- Creates the Spring Container shared by all Servlets and Filters -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- Processes application requests -->
	<servlet>
		<servlet-name>appServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
		
	<servlet-mapping>
		<servlet-name>appServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

Step 6: 

create a folder called a "views" inside the webapp folder which is inside the src->main folder. This is required to add all the .jsp files while working with spring framwork.

Step 7:

Create 2 views (.jsp) inside the views folder. Name the view as product.jsp and success.jsp. right click the view folder and create the jsp files.

Step 8:

create a form tag in product.jsp and add 2 fields.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

<form action="/SpringProduct/success" method="post">

Product Name: <input type="text" name="pname"/>
Product Cost: <input type="text" name="pcost"/>

<input type="submit" value="Product Insert"/>
</form>

</body>
</html>

Step 9: Create a model class with the name Product inside model package.
package model;

public class Product {

	private String pName;
	private int pCost;
	public Product() {
		
	}
	public Product(String pName, int pCost) {
		this.pName = pName;
		this.pCost = pCost;
	}
	public String getpName() {
		return pName;
	}
	public void setpName(String pName) {
		this.pName = pName;
	}
	public int getpCost() {
		return pCost;
	}
	public void setpCost(int pCost) {
		this.pCost = pCost;
	}
}

Step 10: Create a ProductController with below code

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import model.Product;

@Controller
public class ProductController {

	@RequestMapping(value="/",method=RequestMethod.GET)
	public String productsPage() {
		return "product";
	}
	
	@RequestMapping(value="/success", method=RequestMethod.POST)
	public ModelAndView productSuccess(@ModelAttribute("product1") Product product) {
		
		ModelAndView view = new ModelAndView("success");
		return view;
	}
	
}

Step 11:
 Add the below in success.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1> Success ${product1.getpName() }</h1>
</body>
</html>

Step 12: Run your spring Project, start the wildfly server in debug mode.
right click your project and choose debug and select debug in server.

Step 13: When ever you make a change in your code later, right click the project from the server and do a full publish and then debug the project in server.
