Spring Boot項目實踐-員工管理系統（六）·展示員工列表

本次實戰項目主要是借鑑b站上的視頻資源【狂神說Java】SpringBoot最新教程IDEA版通俗易懂完成的，有需求的話，可以直接去b站觀看完整的視頻教程，本文若有不對之處，望不吝賜教，謝謝~
博文前提：

一、新建員工管理控制器

EmployeeController.java

package com.example.employee_management.controller;

import com.example.employee_management.dao.EmployeeDao;
import com.example.employee_management.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;

/**
 * @className: EmployeeController
 * @description: 員工管理控制器
 */
@Controller
public class EmployeeController {

    @Autowired
    EmployeeDao employeeDao;

    /**
     * 員工列表
     * @return
     */
    @RequestMapping("/employees")
    public String list(Model model){

        Collection<Employee> employees=employeeDao.getAllEmployees();
        model.addAttribute("employees",employees);
        return "employees/list";

    }
}

二、抽取前端頁面相同代碼

爲簡化開發並且提高代碼的複用性，這裏將頂部導航欄和側邊欄單獨抽取出來放在commons目錄下的common.html文件中。

common.html

<!DOCTYPE html>

三、啓動項目

啓動項目後在瀏覽器中輸入

localhost:8080/

然後輸入用戶名和密碼後便可進入主頁。

點擊員工管理，便可進入員工列表頁面

但是這個數據是寫死了的（直接寫在前端頁面的代碼裏面），沒涉及讀取數據，這是不行的。

四、修改list.html使其讀取數據

由於讀取數據不止一個，因此需要用到th:each來進行遍歷，具體應放在員工表格哪裏。此外再增加“編輯”和“刪除”按鈕。
list.html
