kronos-example-vertx

English | 简体中文

This is a sample project based on Vert.x + Kronos ORM + JDK 17 + Gradle + Kotlin 2.0.0(2.0.20 is about to be adapted.)

If you would like to learn more about Kronos, please visit Kronos.

Introducing Gradle dependencies

1. Add Kronos dependency

dependencies {
  implementation("com.kotlinorm:kronos-core:0.1.0-SNAPSHOT")
  implementation("com.kotlinorm:kronos-jdbc-wrapper:0.1.0-SNAPSHOT")
}

2. Add Kotlin compiler plugin

plugins {
  id("com.kotlinorm.kronos-gradle-plugin") version "0.1.0"
}

Configure the data source

The sample project uses kronos-jdbc-wrapper, and you can configure the data source in the following way. You can also replace it with another wrapper or customize the wrapper.

import com.kotlinorm.Kronos
import com.kotlinorm.KronosBasicWrapper

class MainVerticle : AbstractVerticle() {
  private val ds = BasicDataSource().apply {
    url = "jdbc:mysql://localhost:3306/kotlinorm"
    username = "root"
    password = "**********"
  }

  override fun start(startPromise: Promise<Void>) {
    Kronos.apply {
      dataSource = { KronosBasicWrapper(ds) }
      fieldNamingStrategy = LineHumpNamingStrategy
      tableNamingStrategy = LineHumpNamingStrategy
    }
    vertx
      .createHttpServer()
      .requestHandler { req ->
        req.response()
          .putHeader("content-type", "text/plain")
          .end("Hello from Vert.x!")
      }
      .listen(8888) { http ->
        if (http.succeeded()) {
          startPromise.complete()
          println("HTTP server started on port 8888")
        } else {
          startPromise.fail(http.cause())
        }
      }
  }
}

Run the project

After running the project, visit the following URL to view the results:

If the interface returns the results shown below, Kronos has run successfully and the compiler plugin is working properly.
