How to connect to oracle database using spring boot

Question

I'm working with Spring Boot application and trying to access an Oracle database. Although it was successfully built, it gives the error below when I am trying to deploy in Kubernetes.

I changed the application.properties file and pom.xml file with below configurations:

Application.yml

 spring.datasource.url=jdbc:oracle:thin:@<IP>:1521:orcl
 spring.datasource.username=<username>
 spring.datasource.password=<password>
 spring.datasource.driver.class=oracle.jdbc.driver.OracleDriver

POM file

 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-jdbc</artifactId>
 </dependency>

Exception

***************************
APPLICATION FAILED TO START

    Reason: Failed to load driver class oracle.jdbc.OracleDriver in either of 
            HikariConfig class loader or Thread context classloader

Answer 1

Maven dependency:

    <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc7</artifactId>
        <version>12.1.0</version>
    </dependency>

application.yml file :

# Oracle settings
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:xe
spring.datasource.username=system
spring.datasource.password=password
spring.datasource.driver.class-name=oracle.jdbc.OracleDriver

Note : driver.class-name

Sometimes you may need to add spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect to application.yml file (for Oracle 10).

Answer 2

Add below dependency and repository in the pom

<dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0.3</version>
    </dependency>

<repositories>
    <repository>
        <id>codelds</id>
        <url>https://code.lds.org/nexus/content/groups/main-repo</url>
    </repository>
   </repositories>

Also add the following properties in the application.properties

    spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
    spring.datasource.url=jdbc:oracle:thin:@localhost:1521:xe(SID)
    spring.datasource.username=system
    spring.datasource.password=pw
