It is common to store configuration properties in external .properties and .yml files. There are various ways of reading external […]Continue reading

Introduction In this article, we will look at Spring Framework’s support of immutable property binding. We described Spring external configuration in this article and also provided a more detailed article about the Java bean properties binding. In this article, we will demonstrate constructor binding using the merchant account configuration in this article. Constructor binding enables […]Continue reading

Introduction In this article, we explained why we should externalise our application configuration data. We also provided configuration examples that use various methods supported by Spring Boot. Within these methods was the Java bean properties binding but it was less detailed. Therefore in this article, we are going to give more details about using the […]Continue reading
