🔹 Spring Boot - Towards Spring Tools 5 - Stereotypes and a new Structural View

The tech blog post discusses enhancements in the upcoming release of Spring Tools 5, focusing on the integration of stereotypes and a new structural view for Spring projects. Traditionally, Spring Tools used a “Go To Symbol” feature to help developers navigate Spring concepts like services and repositories. The new release, in collaboration with Spring Modulith and jMolecules, elevates this by providing a logical structure view that visualizes projects based on stereotypes, grouping elements like web controllers and entities. This view offers customization options, allowing developers to select which stereotypes to display, and it accommodates custom stereotypes through jMolecules annotations or metadata files. Additionally, if a project uses Spring Modulith, the view will reflect its modular structure. The blog post also mentions upcoming features and invites developers to try the latest release candidates. 👉 Read more
