Spring Boot is an excellent tool to bootstrap java application. Most of the references mention how to create a standalone java application, optionally with embedded web server (tomcat or jetty). But Spring Boot supports also creating web applications intended to run within servlet container.

You most likely used Base64 encoding. It’s about encoding any sequence of data as a printable string (digits, lower case and upper case letters). But Base64 has variations. E.g., not every Base64 variant allows safe transfer of any data as URL parameters. For that purpose there is a special dialect of Base64: Url-safe encoding.

Spring Framework offers very flexible means for binding application components. Externalizable properties, composite configuration, nested application contexts and profiles.

Sometimes, it is necessary to control whether particular beans or @Configuration will be loaded or not. Spring Framework v.4.1.x does not provide that feature out of the box. But, hopefully, Spring allows conditional bean initialization (see @Profile implementation and @Configurable). So, I created the annotation @Enabled which allows me to control bean instantiation via properties.

@Enabled indicates that a component is eligible for registration when evaluated expression is true. This annotation should be used in conjunction with Configuration and Bean annotations.

It’s very easy to configure custom SSLSocketFactory for JAX-WS web-service: just specify custom property referring to SSLSocketFactory bean. But there is a nuance…

Jetbrains Idea is a perfect IDE (sorry, Eclipse fans). But, like every tool, sometimes it needs some customization to fit your needs. Today I want to show how to adjust it’s code-generation templates.

When you generates a new class or method using Idea, it creates one using predefined templates. You may modify that template in “Settings -> File and Code templates” section.

When developing java web application it is often annoying to manage third-party javascript libraries. Especially, when it is necessary to upgrade some of them.

The project “WebJars” makes a life easier for such lazyefficient developers, like me :-)

There is a wide range of popular javascript libraries packaged int Jar archives and ready to be included as a dependencies into your project. It is described in the documentation how to configure resource mapping in a web framework of your choice.

JSON has became a de-facto standard for webservices, replacing XML web services. It has native support in web browser clients.

That makes JSON is the standard of choice for UI-oriented services. It has a good support on mobile devices. Also, it provides smaller data payload size compared to XML and it’s very sufficient for high-load systems as it saves a traffic. But what is for data validation? For XML web services there is a XML Schema. It comes ti mind, that similar standard for JSON should be called “JSON Schema”. And it really exists!
