I'm trying to connect with neo4j from Java Spring Boot application. Neo4J is started as Docker image in docker compose file.

I receive following error:

2023-06-22T14:37:36.821+02:00 ERROR 1164 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.transaction.TransactionSystemException: Could not open a new Neo4j session: Unsupported authentication token, scheme 'none' is only allowed when auth is disabled.] with root cause

org.neo4j.driver.exceptions.AuthenticationException: Unsupported authentication token, scheme 'none' is only allowed when auth is disabled.

File docker-compose.yml:

version: '3.1'

services:
  neo4j:
    image: neo4j:4.1.9
    container_name: neo4j-container
    ports:
      - "7474:7474"
      - "7687:7687"

</project>

File application.yaml:

spring:
  data:
    neo4j:
      uri: bolt://localhost
      username: neo4j
      password: password

I have checked and the credentials I am passing are correct. Not sure why is it failing.

I was able to resolve this issue by updating application.yaml file:

spring:
  neo4j:
    uri: bolt://localhost:7687
    authentication:
      username: neo4j
      password: password

It seems that for Spring Boot 3 properties were changed.

Working example of Spring Boot 3 with Neo4J you can find here: https://github.com/wisniewskikr/chrisblog-it-java-springboot/tree/main/others/db/no-sql/java-springboot-helloworld-db-nosql-neo4j-crud
