For the last few days, I have not had time to work on the project. Now there is simple page displayed as an initial project page.

Added spring framework dependencies in pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.billingsystem</groupId>
  <artifactId>BillingSystem</artifactId>
  <version>0.0.1</version>
  <packaging>war</packaging>
  <dependencies>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-core</artifactId>
  		<version>4.3.7.RELEASE</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-web</artifactId>
  		<version>4.3.7.RELEASE</version>
  	</dependency>
  	<dependency>
  		<groupId>org.springframework</groupId>
  		<artifactId>spring-webmvc</artifactId>
  		<version>4.3.7.RELEASE</version>
  	</dependency>
  </dependencies>
</project>

Simple view:

<html>
<body>
	<h1>message : ${message }</h1>
</body>
</html>

Controller:

package com.billingsystem.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
@RequestMapping("/hello")
public class HelloController {

	@RequestMapping(value = "/index", method = RequestMethod.GET)
	public String index(ModelMap model) {
		model.addAttribute("message", "Spring MVC");
		return "hello";
	}
}

Created dispatcher servlet configuration:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	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-4.3.xsd">
	<context:component-scan base-package="com.billingsystem.controller"/>
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/views/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
</beans>

The picture above presents the basic appearance of the page that will appear after run changes. For now, there are not many changes, but it is a necessary attitude to make new changes and work on the application.
