On behalf of the team, I’m pleased to announce the availability of the Spring Data 2021.1.0-M1 milestone release.

The release is built on top of Spring Framework 5.3.9. For your convenience, you can consume this release through Spring Boot 2.6.0-M1, which our team mates on the Boot team will release in about a week.

The 2021.1 release train ships a set of features and dependency upgrades.
The most important changes are:

• Upgrade to Querydsl 5.
• Support for a wide range of Redis 6.2 commands.
• Support for dialect-dependent custom conversions in Spring Data JDBC. This was used to improve the support of java.time types across multiple databases.
• Support for streaming large result sets in Spring Data JDBC.
• Support for AggregateReference in query derivation.
• REF_CURSOR support for stored procedures in Spring Data JPA.
• Upgrade to MongoDB Driver 4.3 and initial support for MongoDB Server 5.0 Time Series.

• Spring Data MongoDB comes with extended capabilities for linking documents and offers, next to the existing DBRef approach, a property-based solution that uses simple values, such as the target _id or a combination of fields to link to another document.
  The sample below shows the reference to a collection of Account documents through their _id in Java code and how it is represented in MongoDB:

  @Document
  class Person {
    @Id
    String id;
    @DocumentReference
    List<Account> accounts;
  }
  

  {
    "_id" : …,
    "accounts" : [ "6509b9e" … ]
  }
  

As part of the 2020.0.0 version of Spring Data, we released Spring Data JDBC 2.1. This article presents the four most interesting changes in this version.

• Use @Value on entity constructor arguments.
• RowMapper and ResultSetExtractor as beans.
• Improved performance for entities.
• Support of Oracles temporal types.

Use @Value on Entity Constructor Arguments

In some cases, not all the data that goes into an entity comes from the ResultSet of a query. You now may provide an @Value annotation with a SPeL expression that is evaluated, and the result is passed as an argument upon construction of the entity.
