I want to mention that I`ve tried all kind of stuffs starting from the other similar topics on stackoverflow, to change dependency and nothing worked for me.

Spring boot main class: Application.java
#EnableTransactionManagement
#SpringBootApplication(exclude = {HibernateJpaAutoConfiguration.class})
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.getSessionCookieConfig().setHttpOnly(false);
super.onStartup(servletContext);
}
}
Later Edit: I uploaded the application.properties file
#Basic Spring Boot Config for Oracle
spring.datasource.url= jdbc:oracle:thin:#//:/
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.jndi-name=jdbc/DEV_ADF_APPLDS
#hibernate config
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.main.allow-bean-definition-overriding=true
I want to be able to perform simple CRUD operations on a database via swagger api caller (code shows only getAll but I do have the rest of code tho).

Answer 1

Usually happens when Spring is missing the spring-boot-starter-data-jpa since Spring infers the EntityManager from the Spring Data JPA which has an out of the box implementation for Hibernate ORM.
Adding the following to project pom.xml usually solves this problem
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
But in your case is available so the offending code is
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
Change to
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

Answer 2

Instead of spring-boot-starter-data-rest, try using the following
"org.springframework.boot:spring-boot-starter-data-jpa"
"org.springframework.boot:spring-boot-starter-jdbc"
Later edit: Also, don't forget to add #EnableTransactionManagement on the spring boot main class or on the database configuration class
