Quarkus Jimmer Extension

Note

Support Kotlin
Kotlin has been supported since 0.0.1.CR7

In most cases you can refer to jimmer's configuration of spring, there is no real difference between the two, only a few differences
Refer to: https://github.com/babyfish-ct/jimmer

TODO: GraphQL
Please let me know if you have any suggestions on these parts

Quick Start

Dependency

Gradle

Java

JPA

// default db

// repository
public interface BookRepository extends JRepository<Book, Long> {

}

// service
@ApplicationScoped
public class BookService {

    @Inject
    BookRepository bookRepository;
    
    public Book findById(long id) {
        return bookRepository.findNullable(id);
    }
}

// if other databases exist

// repository
@DataSource("DB2")
public interface UserRoleRepository extends JRepository<UserRole, UUID> {

}

// service
@ApplicationScoped
public class UserRoleService {

    @Inject
    @DataSource("DB2")
    UserRoleRepository userRoleRepository;
    
    public UserRole findById(long id) {
        return userRoleRepository.findNullable(id);
    }
}

Code

    // Inject JSqlClient or static method Jimmer.getJSqlClient
    // default db
    @Inject
    JSqlClient jSqlClient;
    
    // if other databases exist
    @Inject
    @DataSource("DB2")
    JSqlClient jSqlClientDB2;
    
    public Book findById(int id) {
        return jSqlClient.findById(Book.class, id);
//  or  return Jimmer.getDefaultJSqlClient().findById(Book.class, id);    
    }
    
    public Book2 findById(int id) {
        return jSqlClientDB2.findById(Book2.class, id);
//  or  return Jimmer.getJSqlClient(DB2).findById(Book2.class, id);
    }

Cache

example: CacheConfig.java
use blocking RedisDataSource

The difference with spring integration is need

ValueCommands and HashCommands

quarkus-jimmer-extension static methods are provided

ValueCommands<String, byte[]> stringValueCommands = RedisCaches.cacheRedisValueCommands(redisDataSource);

HashCommands<String, String, byte[]> stringHashCommands = RedisCaches.cacheRedisHashCommands(redisDataSource);
@ApplicationScoped
public class CacheConfig {

    @Singleton
    @Unremovable
    public CacheFactory cacheFactory(RedisDataSource redisDataSource, ObjectMapper objectMapper) {

        ValueCommands<String, byte[]> stringValueCommands = RedisCaches.cacheRedisValueCommands(redisDataSource);

        HashCommands<String, String, byte[]> stringHashCommands = RedisCaches.cacheRedisHashCommands(redisDataSource);

        return new AbstractCacheFactory() {
            @Override
            public Cache<?, ?> createObjectCache(ImmutableType type) {
                return new ChainCacheBuilder<>()
                        .add(new CaffeineBinder<>(512, Duration.ofSeconds(1)))
                        .add(new RedisValueBinder<>(stringValueCommands, objectMapper, type, Duration.ofMinutes(10)))
                        .build();

            }

            @Override

        };
    }

    private static <K, V> Cache<K, V> createPropCache(
