Wenn tomcat gepoolten Datenquelle in springboot mit erhalte ich keine qualifizierten Bean vom Typ ‚javax.sql.DataSource‘

Question

Ich versuche nur mit Federverschluß gepoolt tomcat Datenquelle zu verwenden, indem Sie Eigenschaften in application.yml Datei angeben wie folgt:

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 

ich

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).

ich verstehe nicht, warum springboot versucht, eine eingebettete Datenquelle zu erstellen. Ist das das erwartete Verhalten für eine gepoolte Datenquelle?

Ich sah in einigen Foren, dass Spring-JDBC-Abhängigkeit dieses Problem verursachen kann, so dass ich jede Spring-JDBC-Abhängigkeit ausgeschlossen. Nein ich

Jeder kann helfen, bitte?

Answer 1

So ist die korrekte Einstellung ist

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

Diese 4 Eigenschaften befinden sich unter der Datenquelle, nicht Tomcat.

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