Which steps enable SQLite with Spring-Boot and JPA?

To run SQLite with a Spring-boot (Version 1.2.3.RELEASE) application, I did these three steps:

1. 
   

   use the SQLiteDialect class from Spring boot and SQLite

   
   


2. 
   

   provide a JDBC driver; we used org.xerial:sqlite-jdbc (http://ift.tt/1xR8htX)

   
   


3. 
   

   configure the datasource; here with a spring-boot .yml file:

   
   

   
      spring:
     datasource:
       url: jdbc:sqlite:<full-path-to-file>.db
       username: ...
       password: ...
       driverClassName: org.sqlite.JDBC
       ...
     jpa:
       database: SQLITE
       dialect: that.custom.SQLiteDialect
       hibernate:
         ddl-auto: update
   
   

Now, that's not enough. It ends with a "No enum constant org.springframework.orm.jpa.vendor.Database.SQLITE" error:

Field error in object 'spring.jpa' on field 'database': rejected value [SQLITE]; codes [typeMismatch.spring.jpa.database,typeMismatch.database,typeMismatch.org.springframework.orm.jpa.vendor.Database,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [spring.jpa.database,database]; arguments []; default message [database]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'org.springframework.orm.jpa.vendor.Database' for property 'database'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type java.lang.String to type org.springframework.orm.jpa.vendor.Database for value 'SQLITE'; nested exception is java.lang.IllegalArgumentException: No enum constant org.springframework.orm.jpa.vendor.Database.SQLITE]

Indeed the org.springframework.orm.jpa.vendor.Database class has no SQLITE value, sadly. However, the spring doc (http://ift.tt/1Ihm3H7) states:

If a given PersistenceProvider supports a database not listed here, the strategy class can still be specified using the fully-qualified class name.

That looks like I have to:

1. 
   

   remove the pointless

   
   

   jpa: database: SQLITE

   
   

configuration piece above, and

2. Provide some "strategy class" instead.

Am I on the right path here ?

What do they mean with "strategy class" and how to get or implement it ?
