Örnek - POJO Üretmek

Şöyle yaparız

<plugin>

  <artifactId>jooq-codegen-maven</artifactId>
  <executions>
    <execution>
      <id>generate-postgres</id>

            <packageName>com.example.springbootjooq.model</packageName>
            <directory>target/generated-sources/jooq</directory>
          </target>
        </generator>
      </configuration>
    </execution>
  </executions>
</plugin>

Çalıştırmak için şöyle yaparız. Çıktı target/generated-sources/jooq dizinindedir

mvn clean generate-sources

Örnek - DAO

Şöyle yaparız. Burada DAO üretiliyor ve DAO'lar Spring anotasyonları kullanıyor.

<generate>
  <pojos>true</pojos>
  <pojosEqualsAndHashCode>true</pojosEqualsAndHashCode>
  <javaTimeTypes>true</javaTimeTypes>
  <fluentSetters>true</fluentSetters>
  <!-- Generate the DAO classes -->
  <daos>true</daos>
  <!-- Annotate DAOs (and other types) with spring annotations, 
  such as @Repository and @Autowired for auto-wiring the Configuration instance, 
  e.g. from Spring Boot's jOOQ starter -->
  <springAnnotations>true</springAnnotations>
  <!-- Generate Spring-specific DAOs containing @Transactional annotations -->
  <springDao>true</springDao>
</generate>

Örnek - Kotlin

Şöyle yaparız.

<plugin>
  <groupId>org.jooq</groupId>
  <artifactId>jooq-codegen-maven</artifactId>                         <!--1-->
  <executions>

        <goal>generate</goal>
      </goals>
    </execution>
  </executions>
  <dependencies>
    <dependency>
      <groupId>org.postgresql</groupId>                               <!--2-->
      <artifactId>postgresql</artifactId>
      <version>42.6.0</version>
    </dependency>
  </dependencies>
  <configuration>
    <generator>
      <name>org.jooq.codegen.KotlinGenerator</name>                   <!--3-->
      <database>
        <inputSchema>people</inputSchema>                             <!--4-->
      </database>
      <target>
        <packageName>ch.frankel.blog.reactivedata.jooq</packageName>
      </target>
    </generator>
    <jdbc>                                                            <!--4-->
      <driver>org.postgresql.Driver</driver>
      <url>jdbc:postgresql://localhost:5432/postgres</url>
      <user>postgres</user>
      <password>root</password>
    </jdbc>
  </configuration>
</plugin>

Açıklaması şöyle

1. The version is defined in the parent Spring Boot Starter parent POM
2. Set the necessary database driver(s). Note that one should use the non-reactive driver
3. There's a Kotlin generator!
4. Configure database configuration parameters

openapi-generator plugin

Giriş

Open API içeren yaml dosyasından kod üretir. Yaml dosyasını Swagger Editor ile düzenleriz.

Kod üretmek için şöyle yaparız.

mvn clean compile

generatorName Alanı

Spring için kod üreteceksek spring değeri verilir.

Örnek

Şöyle yaparız

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <version>5.1.0</version>
  <executions>
    <execution>

          <java8>true</java8>
        </configOptions>
      </configuration>
    </execution>
  </executions>
</plugin>

Örnek open-api.yaml dosyası şöyle

openapi: 3.0.3 # version of the specification
info:
  version: '1'
  title: Open API Generator Spring Boot Example

servers:
  - url: http://localhost:8080

paths:
  /parents:

      type: object
      properties:
        status:
          type: string
        errorMessage:
          type: string
      description: Response of the parent.

    Parent:
      allOf:

              format: int64
            parentName:
              type: string
              example: 'Stephen'

Üretilen kod şöyle

org.openapitools.api
 ApiUtil
  ParentsApi
org.openapitools.model
  Parent
  ParentAllOf
  ParentResponse

inputSpec Alanı

yaml dosyasının yerini belirtir

Örnek

Şöyle yaparız

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <version>6.1.0</version>
  <executions>
    <execution>
      <goals>
        <goal>generate</goal>
      </goals>
      <configuration>
        <inputSpec>
          ${project.basedir}/src/main/resources/employee.yaml
        </inputSpec>
        <generatorName>spring</generatorName>
        <apiPackage>org.SwaggerCodeGenExample.api</apiPackage>
        <modelPackage>org.SwaggerCodeGenExample.model</modelPackage>
        <configOptions>
          <interfaceOnly>true</interfaceOnly>
        </configOptions>
      </configuration>
    </execution>
  </executions>
</plugin>

üretilen kodun derlenmesi için şu dependency listesi gerekir

<dependencies>
  <dependency>
    <groupId>io.swagger.core.v3</groupId>
    <artifactId>swagger-annotations</artifactId>
    <version>2.2.2</version>
  </dependency>
  <dependency>
    <groupId>org.openapitools</groupId>
    <artifactId>jackson-databind-nullable</artifactId>
    <version>0.2.2</version>

  <dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
  </dependency>
</dependencies>

Üretilen kod /target/generated-sources/openapi dizinindedir. Kod sadece interface'lerden ibarettir. Daha sonra kendi sınıfımızı üretilen arayüzden kalıtırız. Şöyle yaparız

@RestController
public class EmployeeController implements EmployeeApi {

  @Override
  public ResponseEntity<String> addEmployee(@Valid Employee employee) {
    ...
  }

  @Override
  public ResponseEntity<List<Employee>> getEmployees() {
    ...
  }
}

  </profiles>
</settings>

Tüm komutlarda mvn yerine mvnw kullanılır. Maven Wrapper projede kullanılan maven sürümünü otomatik olarak indirir ve kullanır. Açıklama Gradle için ancak Maven için de geçerli. Açıklama şöyle

The idea behind Gradle’s wrapper is to keep the exact Gradle version along with the project and just enough code to download the full version over the Internet.

Örnek

Şöyle yaparız

mvnw     <-- Linux için
mvnw.cmd <-- Windows için

Örnek

Şöyle yaparız. Burada maven wrapper'a maven olarak 3.6.3 kullanılması belirtiliyor

$ mvn wrapper:wrapper -Dmaven=3.6.3
$ ./mvnw clean package

Maven Wrapper Kullanmıyorsak

Eğer maven wrapper kullanmıyorsak maven-wrapper kullanmaya başlamak için şöyle yaparız.

mvn -N wrapper:wrapper

Artık sadece maven-wrapper.properties dosyasındaki maven sürümünü değiştirerek derleyebiliriz.

maven-wrapper.properties Dosyası

Yolu şöyle

.mvnw/wrapper
  maven-wrapper.properties

İçi şuna benzer

distributionUrl=https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/3.9.3/apache-maven-3.9.3-bin.zip
wrapperUrl=https://repo.maven.apache.org/maven2/org/apache/maven/wrapper/maven-wrapper/3.2.0/maven-wrapper-3.2.0.jar
