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:

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.

    Why do you need Spring Cloud Config server?

    Last month I wrote a primer on concepts around 12 factor app. Before getting into the details of the Spring Cloud Config Server, I must refresh on the principle #3 from the list presented in that post.

    3 – ConfigurationStore config in the environments
    Configuration information must be separate from the source code. This may seem so obvious, but often we are guilty of leaving critical configuration parameters in the scattered in the code. Instead, applications should have environment specific configuration files. The sensitive information like database password or API key should be stored in these environment configuration files in encrypted format.
     The key takeaways from this postulate for a cloud-native microservices application are:
    Do not store configuration as part of the deployable unit (in the case of lead microservice - inside the jar or war if you are still deploying war like the good old days). Instead, store it in an external location and make it easily accessible during run-…

    Changing the root web application in Tomcat 6

    These days I am very busy developing a large and complex web application, which is nearing its first release. This web based product runs on Tomcat 6 and will be deployed on http://www.mydomain.com
    But if I deploy my web application on Tomcat 6, I need to specify the context root. Well this is no good, why will the users of this website be willing to remember the context root. What if the context root changes. In other words the users would not be interest in typing the following - http://www.mydomain.com/myappcontext to visit this site.
    Hence it is necessary that I change the default / root web application of Tomcat and point it to my application. I wanted to try and test this on localhost first. As always I Googled and found a number of posts and none seem to work. I also read the documentation it was helpful in understanding the concepts but was not effective as I could not get it working. Finally after few hours of trial and error one of my colleague Joyeeta Majumdar found the so…

    Part 3 - Integrating Tiles, Thymeleaf and Spring MVC 3

    In this post I will demonstrate how to integrate Apache Tiles with Thymeleaf. This is very simple. The first step is to include the tiles and thymeleaf-tiles extension dependencies. I will include them in the pom.xml. Note we wil lbe using Tiles 2.2.2Listing 1 - parent/pom.xml --- thymeleaf-tiles and tiles dependencies <!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
    <!-- Tiles -->
