java - 在 Spring 中想调用 Empdao 类，但我收到通过字段“empdao”表示的不满足依赖项的错误；
问题描述
我正在尝试调用 EmpDao 类方法，该方法内部有一个 sysout 语句，所以我有 autowire empdao 类并尝试在我的控制器内部调用但出现错误，请告诉我这个问题。

解决方案
您需要告诉 Spring 加载EmpDaouse @Component。
package com.x.dao;
import com.x.model.Emp;
@Component
public class EmpDao {
public void saveEmpObj(Emp emp) {
System.out.println(emp.getEname());
System.out.println("===============>Emp Dao Called<==================");
}
}
