使用docker启动Oracle Database 23c免费开发者版本

以前，为了在开发和验证环境中启动Oracle，使用Docker需要进行一些镜像构建等繁琐的步骤，但现在通过使用https://container-registry.oracle.com/ords/ocr/ba/database/free提供的镜像，变得非常简单。

例如，只是试一下的话，以下的方法就足够了。尽管首次执行 Docker pull 需要相当一段时间。

docker run --name myoracle -p 11521:1521 -e ORACLE_PWD="a" container-registry.oracle.com/database/free:23.2.0.0

以下是用于启动确认的Spring应用程序。

plugins {
  id 'java'
  id 'org.springframework.boot' version '3.1.5'
  id 'io.spring.dependency-management' version '1.1.3'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'

java {
  sourceCompatibility = '17'
}

repositories {
  mavenCentral()
}

dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-jdbc'
  runtimeOnly 'com.oracle.database.jdbc:ojdbc8'
  testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

tasks.named('test') {
  useJUnitPlatform()
}

spring.datasource.url jdbc:oracle:thin:@localhost:11521/FREEPDB1
spring.datasource.username system
spring.datasource.password a

@SpringBootApplication
public class OracleSampleMain implements ApplicationRunner {

  public static void main(String[] args) {
    SpringApplication.run(OracleSampleMain.class, args);
  }

  @Autowired
  DataSource ds;
  
  @Override
  public void run(ApplicationArguments args) throws Exception {
    JdbcTemplate t = new JdbcTemplate(ds);
    System.out.println(t.queryForObject("select 1 from dual", Integer.class));;
  }
}

运行Docker时的启动日志供参考。
