In this tutorial we demonstrate how to generate random property values for configuration properties using Spring Boot. The RandomValuePropertySource class is added – by spring boot – to the classpath. We can use it to produce random String, Integer, Long or UUID values.

Command Line Arguments can be used to configure your application, pass data at runtime, or to overwrite default configuration options. By default SpringApplication will convert any command line option arguments (starting with ‘–‘, e.g. –server.port=9090) to a property and add it to the Spring Environment. Command line properties always take precedence over other property sources. In this tutorial we demonstrate how to pass, parse and access command line arguments using Spring Boot.

Spring Boot allows you to externalize your configuration so you can work with the same application code in different environments. You can use properties files, YAML files, environment variables and command-line arguments to externalize configuration. In the following tutorial we demonstrate how to use the @ConfigurationProperties annotation to map your configuration properties to a type safe configuration class.

Spring Boot Managing Profiles with @Profile Annotation Example

Spring Profiles provides a way to segregate parts of your application configuration and make it only available in certain environments. This is particularly useful when configuring different environments like development and/or production. In the following tutorial we demonstrate how to manage spring profiles with @Profile annotation.

Spring Boot Spring Data JPA with Hibernate and H2 Web Console

The H2 database provides a browser-based web console that Spring Boot can auto-configure for you. In order to let spring auto-configure the H2 Web Console, we have to make sure we are developing a web application, make sure the com.h2database:h2 dependency resides on the classpath and we are using the org.springframework.boot:spring-boot-devtools. You can also manually configure the h2 web console. In the following tutorial we demonstrate how to configure the H2 Web Console using Spring Boot, Spring Data with Hibernate.

Spring Boot Ehcache 2 Caching Example Configuration

Ehcache is an open source, standards-based cache that boosts performance, offloads your database, and simplifies scalability. It’s the most widely-used Java-based cache because it’s robust, proven, full-featured, and integrates with other popular libraries and frameworks. Ehcache scales from in-process caching, all the way to mixed in-process/out-of-process deployments with terabyte-sized caches.
