Spring Web Flow (SWF) aims to be the best solution for the management of web application page flow.

SWF integrates with existing frameworks like Spring MVC and JSF, in both Servlet and Portlet environments. If you have a business process (or processes) that would benefit from a conversational model as opposed to a purely request model, then SWF may be the solution.

SWF allows you to capture logical page flows as self-contained modules that are reusable in different situations, and as such is ideal for building web application modules that guide the user through controlled navigation that drive business processes.

Technology Used:

  1. String 4.3.1
  2. Maven 2.3.2
  3. Tomcat 7
  4. Java 8
  5. IntelljIDEA 14

Project Structure:

spring-hello-word-java-configuration-project-structure

spring-hello-word-java-configuration-project-structure

Dependency:

pom.xml

<configuration>
           <failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>

Do not forgot to add above configuration in pom.xml file. When we are doing developing application using pure java based configuration at that time we do not have any web.xml file so we can skip to find web.xml using above configuration in pom.xml file.

 InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
 viewResolver.setViewClass(JstlView.class);
 viewResolver.setPrefix("/WEB-INF/pages/");
 viewResolver.setSuffix(".jsp");
 return viewResolver;

 }
}

SpringWebConfig.java

        viewResolver.setPrefix("/WEB-INF/pages/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;

    }


}

Java Code:

HelloController.java

package com.springdemo.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("/")
public class HelloController {

    @RequestMapping(value = "demo",method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        model.addAttribute("message", "Hello world!");
        return "hello";
    }
}

 

hello.jsp

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