Java 为什么我会出错？在spring框架中使用构造函数注入Account类属性时

当我运行代码时，它正在打印帐号的account类intead的地址。 请有人帮帮我

//配置类。我没有使用xml

在编写了toString（）方法之后，它工作得很好。在写了toString（）方法之后，我错过了它，它工作得很好。我错过了

您将需要

toString（）

方法，用于

帐户

类，类似于

员工

类。在

toString（）

方法的

Account

类中，如果您想打印，可以使用

accountNumber

。OHHHH是的，谢谢。您将需要

toString（）

方法的

Account

类类似于

Employee

类。在

Account

类的

toString（）

方法中，如果要打印，可以使用

accountNumber

。ohhh是的，谢谢。
