example-kotlin-springboot-graphql

Projeto de exemplo com API GraphQL com dois crud’s simples, utilizando Kotlin, Spring Boot, Gradle etc.

Tecnologias utilizadas

• Kotlin
• Spring Boot
• Gradle
• Docker
• GraphQL
• GraphQL Voyager
• GraphQL GraphiQL
• Spring Data
• Liquibase
• H2 Database
• Jacoco

Utilização e Build

Após a inicialização da aplicação, independente da forma, a mesma pode ser acessada ou ter a sua documentação acessada pelo link http://localhost:PORTA_INICIADA/.

OBS: Ao iniciar a aplicação, também é iniciado um banco de dados, H2 embutido, então não é necessário nenhuma dependência externa para a mesma ser iniciada e acessada.

Links úteis

Após o sistema ser iniciado podem ser acessadas as seguintes URLs.

GraphQL - /graphql

URL para acesso a todos os recursos GraphQL da aplicação.

URL: http://localhost:8080/graphql ou http://localhost:PORTA_INICIADA/graphql.

GraphQL/GraphIQL - /graphiql

URL para acesso a uma IDE iterativa para operações GraphQL.

URL: http://localhost:8080/graphiql ou http://localhost:PORTA_INICIADA/graphiql.

GraphIQL/Voyager - /voyager

URL para acesso a um gráfico iterativa para operações GraphQL.

URL: http://localhost:8080/voyager ou http://localhost:PORTA_INICIADA/voyager.

H2 Database - /h2-console

URL para acesso a base de dados.

URL: http://localhost:8080/h2-console ou http://localhost:PORTA_INICIADA/h2-console.

Dados de acesso

• Setting Name: Generic H2 (Embedded)
• Driver Class: org.h2.Driver
• JDBC URL: jdbc:h2:mem:testdb
• User Name: sa
• Password: `` (vazio)

Utilização em ambiente local

Localmente o projeto pode ser configurado nas ide’s IntelliJ e Eclipse, ambas possuem suporte via plugin para Kotlin, Spring Boot e Gradle.

Build usando artefatos locais (GIT)

OBS: Os arquivos e ferramentas de build, estão contidas dentro do projeto, então para execução do build, só é necessário ter o Java ou o Docker instalado.

Build local com Gradle

# Execução do build
./gradlew build
# Execução da aplicação
java -jar  build/libs/example-kotlin-springboot-graphql-0.0.1-SNAPSHOT

OBS: Com esses comandos a aplicação será iniciada, na porta 8080, mas isso pode ser alterado, informando o parâmetro: -Dserver.port=$PORTA_DESEJADA.

Build local com Docker

# Execução do build
docker build -t app:latest .
# Execução da aplicação
docker run -d -p 8080:8080 app:latest

OBS: Com esses comandos a aplicação será iniciada, na porta 8080, mas isso pode ser alterado, informando o parâmetro docker: -p $PORTA_DESEJADA:8080.

Utilização com Docker (imagem remota do DockerHub)

# Execução da aplicação
docker run -d -p 8080:8080 justiandre/example-kotlin-springboot-graphql:master

OBS: Com esse comando a aplicação será iniciada, na porta 8080, mas isso pode ser alterado, informando o parâmetro docker: -p $PORTA_DESEJADA:8080****************.
