According to http://docs.spring.io/spring-boot/docs/1.4.0.RELEASE/reference/htmlsingle/#boot-features-neo4j there is a #NodeEntityScan annotation that:
You can customize entity scanning locations using the #NodeEntityScan annotation.
According to http://docs.spring.io/spring-boot/docs/1.4.0.M3/api/org/springframework/boot/neo4j/NodeEntityScan.html it existed in version spring-boot 1.4.0.M3
But http://docs.spring.io/spring-boot/docs/1.4.0.RELEASE/api/org/springframework/boot/neo4j/NodeEntityScan.html suggests it doesn't exist in 1.4.0.RELEASE and I can't find any mention of it.
Does this annotation exist in spring boot 1.4.0.RELEASE ? Is this a case where the documentation has not been updated? What should be used instead?
Spring Boot 1.4 has the generic annotation org.springframework.boot.autoconfigure.domain.EntityScan (JavaDoc), which registers the packages to scan for entities for JPA, Neo4J, MongoDB, Cassandra and Couchbase.

As we know that, spring data jpa just adds extra layer on jpa provider. Spring community provides some spring data jpa starter example here
https://spring.io/guides/gs/accessing-data-jpa/#initial
I didn't see any jpa provider used in this example, how could that happen?
Thanks
Spring boot provide jpa
For example, if you want to use Spring and JPA for database access, it is sufficient if you include spring-boot-starter-data-jpa dependency in your project.
in Spring Boot 1.5 application the application class was annotated with:
#EnableAutoConfiguration(exclude = {MetricFilterAutoConfiguration.class, MetricRepositoryAutoConfiguration.class})
These classes were I believe in the package:
import org.springframework.boot.actuate.autoconfigure.*;
Now upgrade to Spring Boot 2.0.2 but those classes are missing, can't find them anywhere.
What changed? How to solve?
Thanks!
Spring Boot’s own metrics have been replaced with support, including
auto-configuration, for Micrometer and dimensional metrics.
if you want to disable metrics set management.endpoint.metrics.enabled=false
there is a complete guide that makes migration a lot easier

Am new to the spring frameworks ,Iam planning to create a Spring Rest application with JPA . am using Mysql database .
I have downloaded the Spring initializer with Web and JPA as dependdencies with Maven. but while Maven install am getting error asking for MYSQL connector jar , so i have adde the maven enetry for the same , on the second try it asking for the hibernate jar .
So am confused like what is the spring-boot-starter-data-jpa dependency doing ? if we need to add the jars into class path , then what is the use of spring-boot-starter-data-jpa ?
spring-boot-starter-data-jpa is a combination of Spring Boot, which itself consists of the Spring framework core and is meant for rapid stand-alone application development, and Spring Data JPA which is Spring's own opinionated abstraction of JPA. It's basically just an interface with a few convenience classes, you still need to supply the JDBC driver for the corresponding database (MySQL in your case) and an actual ORM implementation (the layer that translates your database rows to Java objects and gives you CRUD functionality).
I am trying to write Spring Boot application to connect to a Teiid database, I want to use JPA layer on it. I have configured the JDBC Data Source, but since this not well-known database in Spring JPA libraries do not autodetect this source. I have manually setup "spring.jpa.*" properties too. I do have a Hibernate dialect for this database, and it is on the classpath.
So, how does one need to configure JPA layer for a not well-known database in Spring Boot? Thank you for your time.

This is fairly well defined in the Spring Boot documentation.
You can set this explicitly in the application.properties file
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
I've seen you can use JaVers to serialize changes to a database, but I can't find a good example about Spring or Hibernate integration. I would also know if I can change the generated table names and columns.
Thank!
In Javers doc, there is the example you are looking for:
http://javers.org/documentation/spring-integration/#spring-jpa-example
If you are using Spring Boot, examples for JaVers Spring Boot starter for SQL
http://javers.org/documentation/spring-boot-integration/
We recommend using the second option - JaVers Spring Boot starter
