What is DDDplus?

DDDplus, formerly named cp-ddd-framework(cp means Central Platform：中台), is a lightweight DDD(Domain Driven Design) enhancement framework for forward/reverse business modeling, supporting complex system architecture evolution!

It captures DDD missing concepts and patches the building block. It empowers building domain model with forward and reverse modeling. It visualizes the complete domain knowledge from code. It connects frontline developers with (architect, product manager, business stakeholder, management team). It makes (analysis, design, design review, implementation, code review, test) a positive feedback closed-loop. It strengthens building extension oriented flexible software solution. It eliminates frequently encountered misunderstanding of DDD via thorough javadoc for each building block with detailed example.

In short, the 3 most essential plus are:

1. patch DDD building blocks for pragmatic forward modeling, clearing obstacles of DDD implementation
2. offer a reverse modeling DSL, visualizing complete domain knowledge from code
3. provide extension point with multiple routing mechanism, suited for complex business scenarios

Current status

Used for several complex critical central platform projects in production environment.

Quickstart

Forward modeling

<dependency>
    <groupId>io.github.dddplus</groupId>
    <artifactId>dddplus-runtime</artifactId>
</dependency>

Integration with SpringBoot

@SpringBootApplication(scanBasePackages = {"${your base packages}", "io.github.dddplus"})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

Reverse Modeling

Please check out the 《step by step guide》.

<dependency>
    <groupId>io.github.dddplus</groupId>
    <artifactId>dddplus-spec</artifactId>
</dependency>

Annotate your code With DSL, DDDplus will parse AST and render domain model in multiple views.

mvn io.github.dddplus:dddplus-maven-plugin:model \
    -DrootDir=${colon separated source code dirs} \
    -DplantUml=${target business model in svg format} \
    -DtextModel=${target business model in txt format}

Architecture Guard

mvn io.github.dddplus:dddplus-maven-plugin:enforce \
    -DrootPackage={your pkg} \
    -DrootDir={your src dir}

Known Issues

• reverse modeling assumes unique class names within a code repo
