Guice配置错误：找不到合适的构造函数

Question

我有课程，我试图通过Guice实例化，但我得到了：

Could not find a suitable constructor in com.workspace.myclass. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.

我的代码类似于：

public class MyModule extends AbstractModule {

    @Override
    protected void configure() { }

    myClass<obj> getMyClass(arg1, arg2) {
        Object someObj = new someObj(arg1);
        return myClass<>(someObj, s -> new Obj(arg2, s.getMethod()));
    }
}

public myClass<T extends someClass> {

    public myClass(arg1, Function<obj<T>, obj2<T>> arg2) {

    }

}

public static void main(args[]) {

    Injector injector = createInjector(new MyModule());
    MyClass myClass = injector.getInstance(MyClass.class);
}

Guice无法将lambda解析为MyClass的构造函数吗？

Answer 1

Guice不喜欢我在模块中给出了来自getMyClass的返回类型myClass<obj>，只需返回myClass。

Answer 2

我相信你错过了getMyClass方法中的@Provides注释 您是否尝试使用configure方法中的binder进行绑定？
