On Annotations — Time to Stop the Demons
summary
The talk critiques heavy use of Java annotations in Java EE and Spring (e.g., @Inject, @Autowired) that lead to runtime surprises like failed transactions and NullPointerExceptions despite green tests using mocks. It presents functional, Java 8-based alternatives for concerns such as transactions and security that rely on the compiler and real-code tests rather than container behavior, and discusses how to adopt those approaches alongside existing application servers and legacy code.
