A microservices framework with complete separation of service code from underlying frameworks which can be interchanged without service code changes.
- Complete separation of each service from underlying web framework and data store framework through interfaces.
- So different web frameworks and data stores can be easily used without changing the service code at all.
- Services are composed fluently by injecting web, data, queue, cache and client implementation as needed.
- Instead of auto incrementing sequence auto generated UUID is used for keys (to support distributed servers).

dependencies {
implementation 'com.hackorama.m.core:mcore:0.1.0'
}
new Service() {
private Response hello(Request request) {
if (request.getPathParams().containsKey("name")) {
return new Response("Hello " + request.getPathParams().get("name"));
}
return new Response("Hello world");
}
@Override
public void configure() {
GET("/hello", this::hello);
GET("/hello/{name}", this::hello);
}
}.configureUsing(new SparkServer("Hello")).start();
See UserService.java
Service started with Sparkjava server and an in-memory database.
Service userService = new UserService().configureUsing(new SparkServer("User Service"))
.configureUsing(new MemoryDataStore()).start();
Same service can also be started with Spring Flux web server and a database like Postgresql/MySQL using JDBC
Service userService = new UserService().configureUsing(new SpringServer("User Service"))
.configureUsing(new JDBCDataStore()).start();
For this there is no service code changes needed.
If you check the UserService.java there is no framework specific (Sparkjava/Spring Flux) packages imported into the service class, providing complete separation of service from the underlying frameworks.
