Part 3 - Introducing Project Lombok and thinking the dynamic form model

We are at the verge of writing few beans and I personally hate those getter/setters toString hashCode, equals to be written for each one of them.I am also not too confident or knowleagble about tools like Spring ROO. So what option I have to save myself from these boring boilerplate clode. I can save some by using Project Lombok. Project lombok is available at - http://projectlombok.org/. I will not show here how to integrate it with STS, its straight forward and well documented on the product website.Do not forget to include it as a maven dependency in the parent project to use it in child projects and save some time.

Dynamic form

Creating the dynamic form will be an excellent thing. We have lot of meta data to do that in the domain objects. We can even keep the form meta information in xml or database. The Spring Thymeleaf dialect already has excellent support for forms. For the moment we will put the dynamic form into parking lot and build forms using Thymeleaf. In future if this really becomes an absolute necessary we will revisit the topic.

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 2.2.2 Listing 1 - parent/pom.xml --- thymeleaf-tiles and tiles dependencies    <dependency> <groupId>org.apache.tiles</groupId> <artifactId>tiles-core</artifactId> <version>${tiles.version}</version> <scope>compile</scope> </dependency> <dependency> <groupId>org.apache.tiles</groupId> <artifactId>tiles-template</artifactId> <version>${tiles.version}</version> <scope>compile</s...

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...
