Quick start

Pick the line that matches your Micronaut version:

conta-command	Micronaut	Java	conta-problem-json
0.3.x	5	25	2.x
0.2.x	4	17	1.x

Add the Conta Open repository and the tracing dependency:

repositories {
    mavenCentral()
    maven {
        name = 'contaOpen'
        url = 'https://gitlab.com/api/v4/groups/12992043/-/packages/maven'
    }
}

dependencies {
    implementation "no.conta.command:conta-command-tracing-mn:${contaCommandVersion}"
}

Implement a CommandTracingEventPublisher to decide how traced commands are persisted; the persistence guide wires the whole chain.

Annotate a controller or method with @CommandTracing:

@CommandTracing
@Controller("/orders")
public class OrderController {

    @Post
    public Order createOrder(@Valid @Body CreateOrderCommand cmd) {
        // The first Command parameter is automatically detected and traced
        return orderService.create(cmd);
    }
}

The interceptor finds the Command parameter, and the filter captures the HTTP response to complete the trace.
