Part 1 - Setup the basic project and tools

I am assuming that STS is successfully setup with the Maven and Subclipse plugins. I am running my STS On Ubuntu 10 platform. Some of you may have problems with Subclipse Native connector, just change that to use pure java SVNKit instead.I am sorry I am not going through the design architecture phase but straightway jumping into the project. This is intentional as my goal is see how easy or difficult it is to create a Spring 3 web application progressibly which is highly pluggable, easy to extend, customize and manage.

Launch STS and create a maven web project using (maven-archetype-webapp). The project was named ecrm.

Step 1 : Modify the pom file as shown below:

<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/maven-v4_0_0.xsd">

Step 2: Modify the web.xml to support Servlet 3.0 on Tomcat 7.x

<web-app 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_3_0.xsd"
    version="3.0">
    <!-- Log4j -->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>file:${catalina.home}/temp/effectivcrm/conf/log4j.xml</param-value>
    </context-param>

    <context-param>
        <param-name>log4jExposeWebAppRoot</param-name>
        <param-value>false</param-value>
    </context-param>

    <!-- Log4j listerner -->
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>Spring MVC 3 Servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:conf/spring-*-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Spring MVC 3 Servlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

Note dispatcher servlet parameter contextConfigLocation. It sets up the dispatcher servlet to load configuration files from classpath in a modular way. Thats is from respective jars - for view, controllers, service, domain, repository etc.

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.

How to implement Cache Aside Pattern with Spring?

Problem You want to boost application performance by loading data from a cache and prevent the network trip to the persistent store (and also the query execution). This can be achieved by loading data from a cache. However, you want to load data on demand or lazily. Also, you want the application to control the cache data management – loading, eviction, and retrieval. Forces Improve performance by loading data from cache lazily. Application code controls cache data management. The underlying caching system does not provide read-through, write-through/write-behind strategies (strange really ??). Solution Use cache aside design pattern to solve the problems outlined above. This is also one of many caching patterns/strategies. I believe it is named in this because aside from managing the data store, application code is responsible for managing the cache also. Let's now try to understand how this caching technique works and then explore how it solves the proble...
