In one of my projects I let Spring Boot automatically bind domain objects from the database.
This fails in the reduced unit test setup, because DomainClassConverter is not available. But it can be mocked!
Tag Java
The Google phone number parser & formatter is very helpful to ensure the same number format for user prodived data. To simplify the use in Spring Boot application with Thymeleaf I created a wrapping TagLib/ExpressionFactory.

Sometimes if you do not properly delete objects in a Grails/GORM/Hibernate transaction the following error might occur:
deleted object would be re-saved by cascade (remove deleted object from associations)
This message is presented by the org.hibernate.ObjectDeletedException
After some hours of investigation I found a solution to find the cause!

Ein Stehpult ist ja schön und gut, aber ohne Verbindung zum Computer ist das doch langweilig...
