Raft of warnings on starting Spring Data Neo4j application (which works)

Drivers & Stacks Spring Data Neo4j & Neo4j-OGM

I am using Spring Data Neo4j with Springboot, and the application works.

However, I have a raft of warnings on startup that I'd like to get rid of if possible.

What is making it so unhappy?

Can you share more details on your project. Configuration (application.properties, project layout, dependencies, config class etc.)

Yes for sure! I was not sure what would be useful.

application.properties:

spring.data.neo4j.username=neo4j
spring.data.neo4j.password=set-me-in-the-environment
spring.data.neo4j.uri=bolt://172.17.0.1:7687

project layout (is this what you are after?):

I'm not aware of any relevant config classes that I have. Is that the problem!

A typical Neo class is like this:

package com.greenasjade.godojo;

import java.time.Instant;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import org.neo4j.ogm.annotation.GeneratedValue;
import org.neo4j.ogm.annotation.Id;
import org.neo4j.ogm.annotation.Property;
import org.neo4j.ogm.annotation.NodeEntity;
import org.neo4j.ogm.annotation.Relationship;
import org.neo4j.ogm.annotation.Transient;

@NodeEntity
public class Comment {

    @Transient
    private static final Logger log = LoggerFactory.getLogger(Comment.class);

    @Id @GeneratedValue Long id;

    @Property
    private Instant date;
    public Instant getDate() {return date;}

    @Property
    private Long user_id;
    public Long getUserId() {return user_id;}
    public void setUserId(Long id) {this.user_id = id;}

    @Property
    private String comment;
    public String getComment() {return comment;}

    @Relationship("COMMENT")
    BoardPosition target;

    public Comment() {
        // Empty constructor required as of Neo4j API 2.0.5
    };

    public Comment(BoardPosition parent, String comment, Long user_id) {
        this.target = parent;
        this.user_id = user_id;
        this.comment = comment;
        this.date = Instant.now();
    }

Accessed in this sort of way:

package com.greenasjade.godojo;

import org.springframework.data.neo4j.annotation.Query;
import org.springframework.data.neo4j.repository.Neo4jRepository;

import java.util.List;

public interface Comments extends Neo4jRepository<Comment, Long> {
  // ... queries...

Thanks for your help!
