接口 DataService

所有超级接口:

AutoCloseable

public interface DataService
extends AutoCloseable

Database service facade used by plugins and higher-level modules.

This API no longer uses ServiceLoader/SPI discovery. Create the concrete implementation directly in your runtime module (e.g. core) and pass it around via dependency injection.

Typical lifecycle:

1. Construct implementation
2. init(DbType, DbConfig) to open connections
3. Obtain repositories via repo(Class)
4. Optionally migrate() schemas
5. Call flushAll() on shutdown

方法详细资料

init

void init(DataService.DbType type,
 DataService.DbConfig cfg)

Initialize connection pool / driver by database type and config.

repo

<T,
ID> Repository<T,ID> repo(Class<T> entityType)

Obtain a repository for the annotated entity type.

参数:

entityType - entity class

返回:

repository bound to that entity

migrate

void migrate()

Perform pending schema migrations if supported by the implementation. No-op if unsupported.

flushAll

void flushAll()

Flush all pending changes to the underlying store.

flushOf

<T> void flushOf(Class<T> entityType)

Flush the repository of a specific entity type.

close

default void close()

Close the service. Default behaviour flushes all repositories.
