springbootでTomcatのプールされたデータソースを使用している場合、「javax.sql.DataSource」タイプの適格なBeanがありません

Question

私はspring.batでプールされたTomcatデータソースをapplication.ymlファイルのプロパティを次のように指定することによってのみ使用しようとしています：

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 

私はspringbootが埋め込まれたデータソースを作成しようとしている理由を私は理解していない

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).

を取得します。 これはプールされたデータソースの予想される動作ですか？

いくつかのフォーラムでは、spring-jdbc依存性によってこの問題が発生する可能性があるので、すべてのspring-jdbc依存関係を除外しています。私は「

Answer 1

だから、正しいセットアップでは、設定＆POMは、ファイルをアップロードでき

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

これらの4つのプロパティは、Tomcatではなく、データソースの下にあります。

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

がここDataSourcePropertiesを見てみましょうhttps://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/DataSourceProperties.java
