Java實戰(zhàn)之圖書管理系統(tǒng)的實現(xiàn)

更新時間：2022年03月21日 10:38:04 作者：qq_1334611189

這篇文章主要介紹了如何利用Java語言編寫一個圖書管理系統(tǒng)，文中采用的技術(shù)有Springboot、SpringMVC、MyBatis、ThymeLeaf 等，需要的可以參考一下

一、項目運行

環(huán)境配置：

Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

項目技術(shù)：

HTML +Springboot+ SpringMVC + MyBatis + ThymeLeaf + JavaScript + JQuery + Ajax + maven等等。

二、效果圖

三、核心代碼

登錄控制層

@Controller
public class LoginController {
 
    private LoginService loginService;
 
 
    @Autowired
    public void setLoginService(LoginService loginService) {
        this.loginService = loginService;
    }
 
 
    @RequestMapping(value = {"/", "/login.html"})
    public String toLogin(HttpServletRequest request) {
        request.getSession().invalidate();
        return "index";
    }
 
    @RequestMapping("/logout.html")
    public String logout(HttpServletRequest request) {
        request.getSession().invalidate();
        return "redirect:/login.html";
    }
 
 
    //負責(zé)處理loginCheck.html請求
    //請求參數(shù)會根據(jù)參數(shù)名稱默認契約自動綁定到相應(yīng)方法的入?yún)⒅?
