从@Provides优化我的代码以绑定到我的guice包中

2024-05-21 • 问答

在我的代码中，在模块包中，我使用Google guice包中的@Provides进行绑定。这是我的工作代码。

但是我想使用bind而不是@provides优化我的代码。我尝试了各种方法，但是得到了不同的例外。有人可以建议我解决方案吗？谢谢

    @Provides
    @Singleton
    @Named(MY_CONSTANT)
    public myobjectRepository myobjectRepository(final DatabaseRepository<ObjectDAO> objectDAODatabaseRepository,final DefaultmyobjectDAOTranslator defaultmyobjectDAOTranslator) {
        return new DynamoDBMyRepository(myDAODatabaseRepository,defaultMyDAOTranslator);
    }

    @Provides
    @Singleton
    public DatabaseRepository<myobjectDAO> myobjectDAODatabaseRepository(final DAOWriter<myobjectDAO> daoWriter,final DAORetriever<myobjectDAO> daoRetriever) {
        return new DynamoDBRepository<>(daoWriter,daoRetriever);
    }

    @Provides
    @Singleton
    public DAOWriter daoWriter(final IDynamoDBMapper dynamoDBMapper) {
        return new DAOWriter(dynamoDBMapper);
    }

    @Provides
    @Singleton
    public DAORetriever<myobjectDAO> myobjectDAORetriever(final IDynamoDBMapper dynamoDBMapper) {
        return new DAORetriever<>(dynamoDBMapper,myobjectDAO.class);
    }

bind(MyObjectRepository.class) .annotatedWith(Names.named(MY_CONSTANT)) .to(DynamoDBMyRepository.class) .in(Singleton.class); bind(new TypeLiteral<DatabaseRepository<MyObjectDAO>>(){}) .to(DynamoDBRepository.class) .in(Singleton.class); bind(new TypeLiteral<DAOWriter<MyObjectDAO>>(){}) .to(DAOWriter.class) .in(Singleton.class); bind(new TypeLiteral<DAORetriever<MyObjectDAO>>(){}) .to(DAORetriever.class) .in(Singleton.class);
