Now that we’ve updated the version, let’s see if it compiles: 1 $ mvn compile 2.ģ Failed to execute goal :maven-compiler-plugin: 3.5. In the parent pom.xml we can override the Lombok version via a property so: 1 2 1. We can, however, override the dependency version from Spring Boot. Like most common dependencies, it’s managed by Spring Boot’s dependency management. The version 1.18.12 isn’t managed in our project directly. Looking at the Lombok change log, Java 17 support was added in 1.18.22. It seems our current version 1.18.12 is not compatible with Java 17, it cannot generate code as expected. ![]() It can generate the getters, setters, constructors, logging, etc. Lombok is a java library automating the boilerplate code we all love to hate. ![]() Unfortunately our project failed to compile, but not surprisingly. processing to unnamed module 0x5a47730c -> JavacProcessingEnvironment ( in module jdk.

In the IDE, switch the JDK to Java 17 and in the parent POM set the java.version property to 17. JOSE – for decoding and verifying JWT Tokens.To give you an idea of what we’re talking about, all of the following Spring projects are used in our project, and by one or more applications: All the applications are currently using Java 11 and Spring Boot version 2.3.3-RELEASE. The product consists of an API gateway, exposing REST APIs, multiple back-end applications communicating internally using Kafka and integrating with SAP. They all belong to the same product, which is why they are in a single Maven project. Our project is a mono-repo containing ~20 Spring Boot applications. Together we’re going to get our hands dirty and learn some things along the way. We would like to use Java 17 with one of our existing projects, so I hope you’ll follow along on our journey. We finally have an LTS version, after so many years, that we can use in our enterprise development. Many corporations have policies prohibiting non-LTS JDK versions, which is what makes Java 17 so exciting for so many of us. It’s reasonable: why touch a running system? But there are good reasons for doing so, security being the most important one, and Java 17 can be a great excuse to finally tackle this task. We tend to neglect our existing applications, focusing only on the new ones being actively developed. This is unfortunately still common practice. If your situation is anything like ours, you may have older applications, running happily in production, which haven’t been updated in a while. Instead of starting from a new or recent project (where’s the excitement in that?), we’re going to update an existing Spring Boot application until we can develop new code using Java 17. class IndexController get() ", method = RequestMethod.Java 17 has recently been released, and I’m excited for the many improvements and new features. ![]() Here is an example of the annotation applied to both class and methods. You can then apply additional method-level annotations to make mappings more specific to handler methods. The class-level annotation maps a specific request path or pattern onto a controller. The annotation can be applied to class-level and/or method-level in a controller. To configure the mapping of web requests, you use the annotation. When configuring Spring MVC, you need to specify the mappings between the requests and handler methods. In Spring MVC applications, the RequestDispatcher (Front Controller Below) servlet is responsible for routing incoming HTTP requests to handler methods of controllers. In this post, you’ll see how versatile the annotation is when used to map Spring MVC controller methods. ![]() This annotation maps HTTP requests to handler methods of MVC and REST controllers. Is one of the most common annotation used in Spring Web applications.
