Я использую загрузочные данные Spring JPA 3.3 для подключения к базе данных Oracle 21c, а также использую jdk-22. Я не знаю, почему у меня ошибка org.hibernate.dialect...
Мой application.properties это:
# OracleDB connection settings
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//localhost:11521/XE
spring.datasource.username=user_management
spring.datasource.password=user_management
# HikariCP settings
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=20
spring.datasource.hikari.idleTimeout=30000
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000
spring.datasource.hikari.poolName=HikariPoolBooks
# JPA settings
spring.jpa.database-platform=org.hibernate.dialect.OracleDialect
spring.jpa.hibernate.use-new-id-generator-mappings=false
spring.jpa.hibernate.ddl-auto=update
И мой pom.xml:

Я не знаю, в чем моя ошибка. Спасибо
Я попытался изменить зависимость на
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc11</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc11-production</artifactId>
<version>21.1.0.0</version>
<type>pom</type>
</dependency>
и изменил application.properties на
spring.jpa.database-platform=org.hibernate.dialect.Oracle12cDialect
или
spring.jpa.database-platform=org.hibernate.dialect.Oracle21cDialect
и
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
🤔 А знаете ли вы, что...
Oracle Database 19c - это последняя версия базы данных Oracle на момент завершения моего обучения в сентябре 2021 года.
Я изменил свой JDK на 21 в своем pom.xml и установил JDK-21 на свою Windows...
На сайте Oracle пишут:
Поддерживает спецификацию JDBC 4.3 и может использоваться с JDK8, JDK11, JDK17, JDK19 и JDK21.
для com.oracle.database.jdbc и ojdbc11.jar
