Подключитесь к MongoDB и Postgres с помощью Spring Boot

0 голосов
/ 06 января 2020

Я подключаюсь к MongoDB и Postgres, используя Spring Boot одновременно. Однако я могу подключиться только к Postgres, а не к MongoDB. Ниже мой код, который я запускаю:

application.properties: 

    #spring.user.datasource.url=jdbc:mysql://localhost:3306/user
    #spring.user.datasource.username=root
    #spring.user.datasource.password=admin
    #spring.user.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    #spring.user.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

    mongo.datasource.authentication-database=test
    mongodb.datasource.username=user
    mongodb.datasource.password=pass
    mongodb.datasource.database=test
    mongodb.datasource.port=27017
    mongodb.datasource.host=localhost
    #mongodb.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    mongodb.datasource.uri=mongodb://user:pass@host/test

    spring.booking.datasource.url=jdbc:postgresql://*******/testpost
    spring.booking.datasource.username=user1
    spring.booking.datasource.password=password1
    spring.booking.datasource.driver-class-name=org.postgresql.Driver

    spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true


    #server.tomcat.
    server.port=8800
