if you dont need to config the datasource, you can use the exclude
. like this:
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
it would not register the DataSource with default configuration, then passed the issue for throw Exception

sometimes if you bean configuration in same package it won't work. Like the properties loading bean need to be in separate package. Not sure this answer will be accepted or not , for me it worked after moving below code into different package.
@Bean
public PlatformTransactionManager oracleTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(oracleEntityManager().getObject());
return transactionManager;
}

the connection with a sql database, you must configure datasource in application.properties
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://..
spring.datasource.username=//..
spring.datasource.password=//..
