Lors de l'utilisation de la source de données tomcat pooled dans springboot, je reçois aucun bean qualifiant de type 'javax.sql.DataSource'

Question

J'essaie d'utiliser la source de données tomcat groupée avec démarrage au printemps uniquement en spécifiant les propriétés dans le fichier application.yml comme suit:

spring: 
    data: 
    jpa: 
     repositories: 
     enabled: true 
    datasource: 
    tomcat: 
     max-active: 50 
     max-wait: 10000 
     username: postgres 
     password: root 
     url: jdbc:postgresql://localhost:5432/proj 
     driver-class-name: org.postgresql.Driver 

Je reçois

Caused by: org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Je ne comprends pas pourquoi springboot tente de créer une source de données intégrée. Est-ce le comportement attendu pour une source de données poolée?

J'ai vu sur certains forums que la dépendance de spring-jdbc pouvait causer ce problème, donc j'ai exclu toutes les dépendances de spring-jdbc. Non, je me

Tout le monde peut aider s'il vous plaît?

Answer 1

donc la configuration correcte est

spring: 
    profiles.active: local 
    data: 
    jpa: 
     repositories: 
     enabled: true 

    datasource: 
    type: org.apache.tomcat.jdbc.pool.DataSource 
    username: postgres 
    password: root 
    url: jdbc:postgresql://localhost:5433/proj 
    driver-class-name: org.postgresql.Driver 
    platform: org.hibernate.dialect.PostgreSQLDialect 
    tomcat: 
     max-active: 200 
     max-age: 1000 
     max-wait: 10000 
     removeAbandonedTimeout: 30 
     initial-size: 20 
     validation-query: SELECT 1 
    jpa: 
    database: postgresql 
    generate-ddl: true 
    show-sql: true 
    hibernate: 
     ddl-auto: none 
    database-platform: org.hibernate.dialect.PostgreSQLDialect 

Answer 2

Ces 4 propriétés se trouvent sous datasource, pas tomcat.

username: postgres 
    password: root 
    url: jdbc:postgresql://localhost:5432/proj 
    driver-class-name: org.postgresql.Driver
