类不包含用于自动装配的匹配构造函数 [英] Class doesn't contain matching constructor for autowiring

问题描述

我有两个类

public abstract class AbstractDAO<T> {
    private final MyExecutor<T> myExecutor;
    private final Class<T> clazz;

    public AbstractDAO(MyExecutor<T> myExecutor, Class<T> clazz) {
        this.myExecutor = myExecutor;
        this.clazz = clazz;
    }
}

和

@Component
public class MyDAOImpl extends AbstractDAO<Manager> {
    private final SessionManager sessionManager;
    private final MyExecutor<Manager> myExecutor;

    @Autowired
    public MyDAOImpl(SessionManager sessionManager, MyExecutor<Manager> myExecutor) {
        super(myExecutor, Manager.class);

        this.sessionManager = sessionManager;
        this.myExecutor= myExecutor;
    }
}

抽象类的定义出错说：类不包含用于自动装配的匹配构造函数。

I got an error at the definition of the abstract class saying that: "Class doesn't contain matching constructor for autowiring".

我所做的只是向AbstractDAO的构造函数（即一个类）添加了一个额外的构造函数参数。我之所以需要它，是因为我没有找到一种在运行时从T中检测出来的方法（堆栈流搜索说没有）。

All I did is added an additional constructor parameter to the constructor of AbstractDAO which is a Class. I need this because I didn't find a way to detect this out from T at run time (stackflow search says there isn't one).

我该如何解决？如何传递只能在实现类中确定的类信息？

How can I fix this? How can I pass the Class information which can only be determined in the implementation class?

非常感谢
