[0.2.1] - 10th December 2023

  • BREAKING CHANGE: Better organised DataSourceConfig to segregate Primary and Secondary data sources as per Spring Convention. Also renamed @TargetDataSource to @TargetSecondaryDataSource to avoid confusion.

    Before:

    @Configuration
@EnableMultiDataSourceConfig(
  repositoryPackages = {
    "com.sample"
  },
  exactEntityPackages = {
    "com.sample.project.sample_service.entities.mysql"
  },
  dataSourceConfigs = {
      @DataSourceConfig(dataSourceName = "master", isPrimary = true),
      @DataSourceConfig(dataSourceName = "replica-2"),
      @DataSourceConfig(dataSourceName = "read-replica")
  }
)
public class ServiceConfig {
}

    After:

     @Configuration
 @EnableMultiDataSourceConfig(
    repositoryPackages = {
      "com.sample"
    },
    exactEntityPackages = {
      "com.sample.project.sample_service.entities.mysql"
    },
    primaryDataSourceConfig = @DataSourceConfig(dataSourceName = "master"),
    secondaryDataSourceConfigs = {
        @DataSourceConfig(dataSourceName = "replica-2"),
        @DataSourceConfig(dataSourceName = "read-replica")
    }
 )
 public class ServiceConfig {
 }

  • Allow @TargetSecondaryDataSource to be placed on any Repository, not just JpaRepository.

  • Adaptive EntityManagerFactory for TransactionManager will be generated based on LocalContainerEntityManagerFactoryBean. Decoupled from Javax/Jakarta implementations.

  • Allow possibility for overriding different JPA properties for each data source by adding @DataSourceConfig.overridingJpaPropertiesPath field. By default, it will take the default spring.jpa.properties path.

[0.1.2] - 6th October 2023

  • HOTFIX: Fix @EnableJpaRepositories.basePackages being empty for secondary data sources when @EnableMultiDataSourceConfig.generatedRepositoryPackagePrefix is not set. Instead, it will be set to the package of the @EnableMultiDataSourceConfig annotated class followed by .generated.repositories and then the snake-cased datasource name.
  • Default @EnableMultiDataSourceConfig.generatedConfigPackage changed to the package of the @EnableMultiDataSourceConfig annotated class followed by .generated.config instead of @EnableMultiDataSourceConfig.generatedRepositoryPackagePrefix followed by .config.
  • No repositories will be scanned for data sources which do not have a @TargetDataSource.
  • Refactor internal logic for more readability.

[0.1.1] - 26th September 2023

PR#13

  • BREAKING CHANGE: Configs must be defined for each data source now under @EnableMultiDataSourceConfig.@DataSourceConfig.
  • BREAKING CHANGE: @MultiDataSourceRepository has been renamed to @TargetDataSource for easier understanding.
  • Incremented version of Junit and Mockito.
  • Restructured DataSource Level configuration for more readability and utility.

PR#11, PR#12

  • Cosmetic improvements to generated code to include comment explaining hibernate bean container injection reasoning
  • Turned utils into singleton classes instead of static classes, and enforced them with Unit Tests.
  • Improved documentation

[0.0.5] - 23rd July 2023

  • Unit Tests added for most major elements.
    • Had to use reflection for unit tests of generated Repository classes. It could be better.
  • Made generated config classes abstract-able by introducing IMultiDataSourceConfig interface.
  • Some internal method name changes for consistency.
  • Excluded SLF4J, even as a provided dependency, as it is not required.

[0.0.4] - 22nd July 2023

  • Fixed Sonatype Issues:
  • Made Error Messages final static constants in a separate class: io.github.dhi13man.spring.datasource.constants.MultiDataSourceErrorConstants.
  • Changed name of certain classes by adding MultiDataSource prefix to avoid name clashes in client code.

[0.0.3] - 19th June 2023

  • Remove hardcoded DataSource type, and relevant legacy code for increased application-properties-based flexibility with DataSource type.

[0.0.2] - 18th June 2023

  • Improvements to default code generation package config.
  • Proper isMethodSignatureMatching check while overriding and throwing unsupported exception in base Repository methods to ensure only overriden, annotated methods are supported.
  • Fix Dependabot Issue #1

[0.0.1] - 18th June 2022

  • Initial Release with full working implementation of @EnableMultiDataSourceConfig and @MultiDataSourceRepository
  • with relevant config.
  • Setup for Central Maven Repository Deployment with changed group ID and packages.
  • Documentation and Guidelines.
