# Hikari CPの場合、urlのかわりにjdbc-urlを使う
spring:
  datasource1:
    jdbc-url: jdbc:postgresql://localhost:5432/postgres
    username: postgres
    password: pass
    driver-class-name: org.postgresql.Driver
  datasource2:
    jdbc-url: jdbc:hsqldb:mem:test
    username: sa
    password:
    driver-class-name: org.hsqldb.jdbc.JDBCDriver
