我刚刚开始学习dagger2,面对一个看起来像个bug的奇怪问题.这是模块:

@Module
public class SimpleModule {

    @Provides
    Cooker providerCooker() {

        return new Cooker("tom", "natie");
    }
}

零件:

@Component(modules = SimpleModule.class)
public interface SimpleComponent {

    void inject(DaggerTestActivity activity);

}

接口:

public interface CoffeeMaker {

    String makeCoffee();
}

执行:

  public class SimpleMaker implements CoffeeMaker {

        Cooker mCooker;

        @Inject
        public SimpleMaker(Cooker cooker) {

            this.mCooker = cooker;

        }

        @Override
        public String makeCoffee() {

            return mCooker.makeCoffee();
        }
    }

电饭煲:

public class Cooker {

    String name; 
    String coffeeKind;


    public Cooker(String name, String coffeeKind) {
        this.name = …

我从生产\xe3\x80\x82\n错误分析期间发生异常。我的项目数据库有空间。项目中没有使用多进程。数据库机房已经封装了事务操作。我不知道为什么数据库被锁定。希望得到您的帮助\xef\xbc\x8c谢谢！
