Spring Boot 1.4.0 RC1 Release Notes

For changes in earlier milestones, please refer to:

Upgrading from Spring Boot 1.4.0 M3

See instructions in the 1.4.0.M3 release notes for upgrading from v1.4.0.M2 and earlier.

MongoDB 3

The default version of Mongo’s Java Driver is now 3.2.2 (from 2.14.2) and spring-boot-starter-data-mongodb has been updated to use the new, preferred mongodb-driver artifact.

The auto-configuration for Embedded MongoDB has also been updated to use 3.2.2 as its default version.

Spring Batch Starter

The spring-boot-starter-batch starter no longer depends on an embedded database. If you were relying on this arrangement, please add a database (driver) of your choice, e.g.


If you had an exclusion on hsqldb as you were already configuring your own, you can now remove the exclusion.


Spring Boot nows uses Hibernate 5.0.9.Final by default. If you want to use Hibernate 5.2.x, updating only the version works as of 5.2.1.Final since the Hibernate team has re-introduced hibernate-entitymanager.

Server header

The Server HTTP response header is no longer set unless the server.server-header property is set.


The @org.springframework.boot.orm.jpa.EntityScan annotation has been deprecated and should be replaced with @org.springframework.boot.autoconfigure.domain.EntityScan or explicit configuration.

For example, if you have following configuration:

import org.springframework.boot.autoconfigure.SpringApplication;
import org.springframework.boot.orm.jpa.EntityScan;

public class MyApplication {

    // ....


If you’re using an auto-configured LocalContainerEntityManagerFactoryBean, switch to:

import org.springframework.boot.autoconfigure.SpringApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;

public class MyApplication {

    // ....


Or if you’re defining your own LocalContainerEntityManagerFactoryBean drop the @EntityScan annotation entirely and either call LocalContainerEntityManagerFactoryBean.setPackagesToScan(…​) or make use of the EntityManagerFactoryBuilder packages(…​) method:

public LocalContainerEntityManagerFactoryBean entityManagerFactory(
        EntityManagerFactoryBuilder builder) {
    return builder

New and Noteworthy

Check the configuration changelog for a complete overview of the changes in configuration.

Unified @EntityScan annotation

org.springframework.boot.autoconfigure.domain.EntityScan can now be used to specify the packages to use for JPA, Neo4J, MongoDB, Cassandra and Couchbase. As a result, the JPA-specific org.springframework.boot.orm.jpa.EntityScan is now deprecated and NodeEntityScan introduced in a previous milestone has been removed.

Third-party library upgrades

A number of third party libraries have been upgraded to their latest version. Updates include Jetty 9.3, Tomcat 8.5, Jersey 2.23, Artemis 1.3, Ehcache 3.1, Elasticsearch 2.3, Spring REST Docs 1.1, Spring AMQP 1.6 & Spring Integration 4.3.

Several Maven plugins were also upgraded.

RestTemplate builder

A new RestTemplateBuilder can be used to easily create a RestTemplate with sensible defaults. By default, the built RestTemplate will attempt to use the most suitable ClientHttpRequestFactory available on the classpath and will be aware of the MessageConverter instances to use (including Jackson). The builder includes a number of useful methods that can be used to quickly configure a RestTemplate. For example, to add BASIC auth support you can use

public RestTemplate restTemplate(RestTemplateBuilder builder) {
    return builder.basicAuthorization("user", "secret").build();

The auto-configured TestRestTemplate now uses the RestTemplateBuilder as well.


The @RestClientTest annotation can be used if you want to test REST clients. By default it will auto-configure Jackson and GSON support, configure a RestTemplateBuilder and add support for MockRestServiceServer.

Jest support

Spring Boot auto-configures a JestClient and a dedicated HealthIndicator if Jest is on the classpath. This allows you to use Elasticsearch even when spring-data-elasticsearch isn’t on the classpath.

Spring Session JDBC Initializer

If Spring Session is configured to use the JDBC store, the schema is now created automatically on startup.

Secured connection for Artemis/HornetQ

Spring Boot now allows to connect against a secured Artemis/HornetQ broker.


  • The actuator exposes a new headdump endpoint that returns a GZip compressed hprof heap dump file

  • Spring Mobile is now auto-configured for all supported template engines

  • The Spring Boot maven plugin allows to bundle system scoped artifacts using the new includeSystemScope attribute

  • spring.mvc.log-resolved-exception enables the automatic logging of a warning when an exception is resolved by a HandlerExceptionResolver

  • spring.data.cassandra.schema-action you be used to customize the schema action to take on startup

Deprecations in Spring Boot 1.4.0.RC1

  • The spring-boot-starter-hornetq starter has been deprecated in favour of using spring-boot-starter-artemis

  • management.security.role has been deprecated in favour of management.security.roles

  • The @org.springframework.boot.orm.jpa.EntityScan annotation has been deprecated in favor of @org.springframework.boot.autoconfigure.domain.EntityScan or explicit configuration.
