Part 3 - Introducing the domain objects and first lead create view

As I decided that I will go with static forms instead of dynamic ones, I set sail creating the createlead.html page with Thymeleaf support and Spring MVC.The listing below shows the form:

Listing 1 - createlead.html

Next step is to modify the guest controller and introduce a new savelead controller as shown in Listing 2

Listing 2 - SaveLeadController.java

package com.effectivcrm.controller;

import lombok.extern.slf4j.Slf4j;

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

import com.effectivcrm.domain.Address;
import com.effectivcrm.domain.Lead;

@Controller
@Slf4j
public class SaveLeadController {

@ModelAttribute
public Lead initLead(){
Lead lead = new Lead();
lead.setAddress(new Address());

log.info("Lead = {}", lead);
log.info("Address = {}", lead.getAddress());

return new Lead();
}

@RequestMapping("/savelead")
public String saveLead(Lead lead){
log.info("Lead for saving = {}", lead);
return "createlead";
}

@RequestMapping(value="/createlead")
public String createLead(){
return "createlead";
}

}

 

Now the most important thing we introduce the domain objects. For this we need the Hibernate dependencies. These are added in the parent pom.xml. The domain object project is created by Maven quickstart archetype. The domain object Lead extends from PersistentObject class and also embeds an Address object. Note the use of nested object with Spring EL and Thmyeleaf in Listing 1. All source code is available in SVN.

So whats next in part 3

  • Tiles integration
  • Internationalized messages
  • Validation
  • Spring Security integration
  • Introduction of service layer
  • Introduction of repository layer
