    package com.jokerdig.controller;

    import com.jokerdig.dao.EmployeeDao;
    import com.jokerdig.pojo.Employee;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;

    import java.util.Collection;

    /**

    * @data 2022/7/20 - 10:18
    **/
    // 员工controller
    @Controller
    public class EmployeeController {

    @Autowired
    EmployeeDao employeeDao;

    // 员工展示
    @RequestMapping("/emps")
    public String employeeList(Model model){
    Collection<Employee> emList = employeeDao.getAll();
    model.addAttribute("emList",emList);
    return "emp/list";
    }
    }
  2. MyMVCConfig中的addViewControllers下注册视图

    1
    registry.addViewController("/list.html").setViewName("emp/list");
  3. templates下新建commons/commons.html,并提取主页面的导航栏和侧边栏
