Spring Boot AutoConfiguration doesn't support Neo4J bolt driver

[xenoterracide]

Enhancement

https://neo4j.com/blog/spring-data-neo4j-4-1-milestone-1/ suggests that Spring Data does support it, though I can't find a reference in the spring data docs, so maybe not.

I can't find anything in spring boot docs either. This is the error I get on the server when configuring with a bolt:// uri. If I need to produce an example product I can.

I did add this to my dep list

<dependency>
    <scope>runtime</scope>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j-ogm-bolt-driver</artifactId>
    <version>${neo4j-ogm.version}</version>
</dependency>

the short Could not deduce driver to use based on URI 'bolt://localhost:7687

since bolt is the binary protocol driver it would be nice to support it by configuring spring.data.neo4j.uri=bolt://...

In the event this is a documentation oversight, please add some

Please show us what you've tried.

Boot can't deduce the driver to use for a bolt:// URI. That should be clear from the code that's throwing the exception.

Have you tried explicitly configuring the driver too?

Perhaps we can drop that exception if the DriverConfiguration can deduce the driver type from the URL.

There was a reason why I didn't support bolt initially but I don't remember right now what it was. I'll have a look to the code again.

[xenoterracide]

I could look into implementing this, but ... where is the code that actually does this?

Neo4jProperties: if you can give that a try and submit a PR that'd be nice.
