Migrating to Java 9
Java 9, after many delays and failed votes, looks to be finally arriving this September.
Java 9 will bring several new features: enhancements to Streams, a REPL, improvements to Collections, among others. But by far the biggest and most controversial change is Jigsaw. Jigsaw is introducing modularity to the JDK, a long topic in and of itself, but it is one of the major reasons upgrading to Java 9 will be more difficult than previous major releases of Java.
In this blog we will take a look at some of the benefits of running in a Java 9 environment, how to migrate a Spring Boot application to Java 9, and finally review some of the common problems you may run into and strategies for resolving them…
Auto-Publishing & Monitoring APIs With Spring Boot
If you are heading down the path of a Microservices style of architecture, one tenant you will need to embrace is automation. Many moving parts are introduced with this style of architecture. If successful, your environment will have a plethora of service APIs available that the enterprise can consume for application development and integration.
This means that there must be a way that available API documentation can be discovered. API information needs to be effectively communicated throughout the enterprise that shows where APIs are used, how often APIs are used, and when APIs change. Not having this type of monitoring in place will hinder and possibly cripple the agility benefits that a Microservice style of architecture can bring to the enterprise.
This blog will describe how Swagger/OpenAPI documentation can be applied to aย Spring Boot implementation. We will show how API documentation and monitoring can be automatically published toย an API documentation portal.
As an example, we introduce a reference Spring Boot API CRUD application (using Spring MVC/Data with Spring Fox) and set up the automatic publishing of API documentation and statistics to documentation portal GrokOla. In the example, we introduce two open source utilitiesย to help and allow published APIs the ability toย be searched and notify users whenย changed….
