Java DDD is developed based on maven.

Java DDD is developed based on maven.

My current understanding of DDD is:

1. In addition to basic data operations, you can also migrate some common methods or classes to Infrastructrue.

2. For the domain layer, you can declare the operation interfaces of each aggregation root: for example, IXXXRepository is implemented at the Infrastructrue layer.

3. the pom. xml package in Infrastructrue depends on the domain layer.

Business problems:

Now I want to put some enumeration definitions in Infrastructrue. enumeration is used at the domain layer, but maven does not allow circular dependencies. How can I solve this problem?

 

Can I define enumeration as a VO object on the domain layer, but I don't want to do this.

What should I do if I put it on the Infrastructrue layer?

 

This article is an open question. I hope you can give me some suggestions.
