应用程序编译时出现springboot错误

Question

I have a problem with springboot after creating my springboot project. I filled out my application.properties to have access to the database. And then I tried to compile by maven and I encountered these errors. I was unsuccessful.

 ##DataSource settings spring.datasource.url=jdbc:oracle:thin:@//localhost:1521/BD_GESTION_OPERATION?createDatabaseIfNotExist=true&userSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC spring.datasource.username=system spring.datasoutce.password= spring.datasource.driver-class-name=com.oracle.jdbc.Driver ##Keep the connection alive if idle for a long time (needed in production) spring.datasource.testWhileIdle=true spring.datasource.validationQuery=SELECT 1 ##Disabling spring basic security security.basic.enabled=false ##Start up port server.port=8082 ##Specify DBMS spring.jpa.database=ORACLE ##Show/Hide SQL queries spring.jpa.show-sql=false ##Hibernate DDL Auto (create, create-drop, update) spring.jpa.hibernate.ddl-auto=update ##Naming strategy spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy ##Dialect spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle11gDialect

 The errors are as follows: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0;

Seems to me you forgot to provide the dependency in maven

<dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc</artifactId>
        <version>8</version>
        <scope>system</scope>
        <systemPath>d:/projects/ojdbc8.jar</systemPath>
    </dependency>

Note that to get that working you need to download the jar file. here is a quick explanation https://www.mkyong.com/jdbc/connect-to-oracle-db-via-jdbc-driver-java/

Note Im asumming you are missing that but i did not look at your pom file
