3. •オープンソースのPaaS基盤
•Cloud Foundry Foundationで開発されて
いる、ベンダロックインを回避
•パブリッククラウド / プライベートクラウ
ド問わず、マルチクラウドに対応

38. 環境変数 VCAP_SERVICES
spring.datasource.url=${vcap.services.mydb.credentials.jdbcUrl}
spring.datasource.username=${vcap.services.mydb.credentials.username}
spring.datasource.password=${vcap.services.mydb.credentials.password}
String json = System.getenv("VCAP_SERVICES");
// Parse JSON ...
Spring Bootの場合 (application-­‐cloud.properties)
一般的なJavaアプリケーションの場合
実はBuildpackにより、自動でDataSourceなどのBeanが差し替えられるのでこの設定は不要
