Spring + Hibernate - Oracle UCP-Verbindungspool verwenden

Question

Ich habe eine grundlegende Spring-Boot-Anwendung und ich habe erfolgreich mit einer Oracle DB verbunden. Allerdings würde ich lieber den UCP-Verbindungspool von Oracle als den Standard verwenden. Ich habe folgende application.properties config:

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver 
spring.datasource.type=oracle.ucp.jdbc.PoolDataSourceImpl 
spring.jpa.database-platform=org.hibernate.dialect.OracleDialect 

Wenn jedoch die db Abfrage erhalte ich:

oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager MBean: oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager: java.sql.SQLException: Invalid Universal Connection Pool configuration: java.sql.SQLException: Unable to create factory class instance with provided factory class name: java.lang.ClassNotFoundException:

ich die ucp.jar habe in meinem Classpath (von Oracle-Website heruntergeladen).

Answer 1

Am Ende des Tages gab ich die Verwendung von streng Konfigurationseigenschaften auf und befolgte die hier aufgeführten Schritte: http://ebcidicrants.blogspot.bg/2015/07/using-oracle-ucp-as-default-datasource.html. Dies hat den Trick mit einer geringfügigen Änderung in Bezug auf das Lesen der Konfiguration

@ConfigurationProperties(prefix="datasource.ucp") 
@Component 
public class UCPDataSourceProperties { ... } 

Und

@Bean 
@Primary 
@Autowired 
public DataSource ucpDataSource(UCPDataSourceProperties properties) throws SQLException { ... }
