This operator is the key instrument for an OOP developer.
And the best method of instantiation is operator new. We can’t configure our objects if they are real objects. There should not be any “configurations” in OOP. If you can stay away from it, you will do yourself a big favor.
#Annotations in java software#
Let me repeat it again-Spring Framework is one of the worst software products in the Java world. Spring XML configuration mechanisms is a perfect example of terrible design. What could be worse than annotations? Configurations. What should be used instead? Object composition. The bottom line is that annotations are bad.
I regret that I didn’t understand it two years ago, when I started to work with jcabi-aspects. First, you attach the annotation to the getter:Ĭlass Retry is how JAXB works, when you want to convert your POJO to XML. They are containers, sessions, managers, controllers, etc. Annotations by themselves are not the key motivator, but they help us and encourage us by tearing objects apart and keeping parts in different places. These decorators are benign and do not execute any. Check this post, it explains what is wrong about ORM: ORM Is an Offensive Anti-Pattern. Annotations are decorators that are applied to Java constructs, such as classes, methods, or fields, that associate metadata with the construct. The same is true about ORM (JPA/Hibernate), where annotations are being actively used. That’s because we don’t want to duplicate the same code over and over again, right? That’s correct, duplication is bad, but tearing an object apart is even worse. We move functionality outside of our objects and put it into containers, or somewhere else. Annotations basically provoke us to make the containers and use them. This article explains why Dependency Injection containers are a wrong idea in the first place: Dependency Injection Containers are Code Polluters.
