-

-
Add Value Expression support to Repository Query Methods
Details
-
Spring Data Build - 3.4
By default the Spring Data infrastructure only auto-detects fragments, custom extensions to a repository interface, within the repositories base-package. Therefore, fragments residing in another location or contributed by an external archive will not be found if they do not share a common namespace.
New in 3.4, spring.factories allows you to circumvent this restriction by providing both, fragment interface and implementation data as outlined in the following example.
package com.acme.search;
public interface SearchExtension<T> {
List<T> search(String text, Limit limit);
}
class DefaultSearchExtension<T> implements SearchExtension<T> {
// ...
}com.acme.search.SearchExtension=com.acme.search.DefaultSearchExtensionpackage io.my.movies;
interface MovieRepository extends CrudRepository<Movie, String>, SearchExtension<Movie> {
}We expanded Value Expression support (general support introduced earlier in 2024.0) to Repository Query methods. You can now leverage property-placeholders in Query methods annotated with @Query.
SQL and JPQL query parsers were refined for an enhanced QueryRenderer model. Also, the internal organization was refactored to decouple query introspection from actual query rewriting. While there is no change in behavior we were able to reduce parsing overhead significantly.
We removed a considerable amount of deprecated API.

The attribute allows different duration formats like 10s, 3h,… as well as expression (#{@mySpringBean.timeout}) and property placeholder (${my.property.timeout}) syntax.
@Table and @UserDefinedType now accept a keyspace attribute to use a different keyspace than the CQL session keyspace when interacting with these without the need for intermediate USE <keyspace> statements. This feature can leave the CQL session in the configured keyspace and eliminates the need to run multiple CQL sessions while your application accesses data from a different keyspace.
Additionally, you can configure a KeyspaceProvider for StatementFactory that is used with CassandraTemplate and its asynchronous and reactive variants.
CassandraTemplate template = …;
template.getStatementFactory().setKeyspaceProvider((entity, tableName) -> …);KeyspaceProvider by default uses the keyspace configured in CassandraPersistentEntity which represents the model of @Table and @UserDefinedType classes.
We introduced SpecificationBuilder and CqlGenerator as entry points for easier CQL specification discoverability. Previously, specifications were loosely coupled in the specification package. Code that wanted to generate CQL from specifications had to look up the appropriate CQL generator and use it with the specification.
This is much easier now:
CqlSpecification createKeyspace = SpecificationBuilder.createKeyspace("my_keyspace")
.with(KeyspaceOption.REPLICATION, KeyspaceAttributes.newSimpleReplication())
.with(KeyspaceOption.DURABLE_WRITES, true);
// results in CREATE KEYSPACE my_keyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'} AND durable_writes = true
String cql = CqlGenerator.toCql(createKeyspace);
CreateTableSpecification createTable = CreateTableSpecification.createTable("my_table")
.partitionKeyColumn("last_name", DataTypes.TEXT)
.partitionKeyColumn("first_name", DataTypes.TEXT)
.column("age", DataTypes.INT);
// results in CREATE TABLE my_table (last_name text, first_name text, age int, PRIMARY KEY(last_name, first_name))
String cql = CqlGenerator.toCql(createTable);Jedis scripting commands (EVAL/EVSALSHA and SCRIPT …) can not be used in transactions and pipelining. This restriction was rooted in missing proper Lua support in early Jedis versions.
With this revision, we deprecate our own MicrometerTracingAdapter and support classes as the Micrometer integration in Lettuce has already been established for several versions. Use Lettuce’s io.lettuce.core.tracing.MicrometerTracing implementation instead of MicrometerTracingAdapter.
The deprecated integration will be removed with the next major revision.
We introduced a customization mechanism for Jedis to apply customizations to JedisClientConfig. You can register a customizer through JedisClientConfigurationBuilder.customize(…) as shown in the following example:
JedisClientConfiguration.builder()
.customize(builder -> {
builder.resp3()
.clientSetInfoConfig(new ClientSetInfoConfig("spring"));
}).build();-
