Question

我有一项简单的服务：

public class AccountService implements IAccountService {

    @Inject
    IAccountDAO accountDAO;

}

本课程由我的模块提供：

@Module(library = true )
public class ServiceModule {
    @Provides @Singleton
    IAccountService provideAccountStoreService(IAccountDAO accountDAO) {
        IAccountService service= new AccountService();
        //Somehow set the accountDAO inside service
        return service;
    }

    @Provides @Singleton
    IAccountDAO accountDAO provideAccountDAO() {
        return new AccountDAO();
    }

}

有没有办法让匕首注射＆＃34;服务＆＃34;我退回之前和它注入其他物体之前？

好吧，它比我想象的要容易（实际上在匕首主页上显示为一个例子）：

@Module(library = true )
public class ServiceModule {
    @Provides @Singleton
    IAccountService provideAccountStoreService(AccountService service) {
        return service;
    }

    @Provides @Singleton
    IAccountDAO accountDAO provideAccountDAO() {
        return new AccountDAO();
    }

}

在Dagger中的@Provides方法中使用注入
