5.登錄控制器：

import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.*;

@Controller
@Slf4j
public class LoginController {
    /**
     * 登錄頁面
     */
    @GetMapping(value={"/", "/login"})
    public String login(){
        return "admin/loginPage";
    }
     * 登錄操作
    @RequestMapping("/loginSubmit")
    public String login(String username, String password, ModelMap modelMap)
    {
        //參數(shù)驗證
        if (StringUtils.isEmpty(username) || StringUtils.isEmpty(password))
        {
            modelMap.addAttribute("message", "賬號密碼必填！");
            return "admin/loginPage";
        }
        //賬號密碼令牌
        AuthenticationToken token = new UsernamePasswordToken(username, password);
        //獲得當前用戶到登錄對象，現(xiàn)在狀態(tài)為未認證
        Subject subject = SecurityUtils.getSubject();
        try
            //將令牌傳到shiro提供的login方法驗證，需要自定義realm
            subject.login(token);
            //沒有異常表示驗證成功,進入首頁
            return "admin/homePage";
        catch (IncorrectCredentialsException ice)
            modelMap.addAttribute("message", "用戶名或密碼不正確！");
        catch (UnknownAccountException uae)
            modelMap.addAttribute("message", "未知賬戶！");
        catch (LockedAccountException lae)
            modelMap.addAttribute("message", "賬戶被鎖定！");
        catch (DisabledAccountException dae)
            modelMap.addAttribute("message", "賬戶被禁用！");
        catch (ExcessiveAttemptsException eae)
            modelMap.addAttribute("message", "用戶名或密碼錯誤次數(shù)太多！");
        catch (AuthenticationException ae)
            modelMap.addAttribute("message", "驗證未通過！");
        catch (Exception e)
        //返回登錄頁
     * 登出操作
    @RequestMapping("/logout")
    public String logout()
        //登出清除緩存
        subject.logout();
        return "redirect:/login";
}

6.前端登錄頁面：

<div>
        <div><p>cxh電商平臺管理后臺</p></div>
        <div>
            <form name="loginForm" method="post" action="/cxh/loginSubmit" onsubmit="return SubmitLogin()" autocomplete="off">
                <input type="text" name="username" placeholder="用戶名"/>
                <input type="password" name="password" placeholder="密碼" autocomplete="on">
                <span>${message}</span>
                <input type="submit" value="登錄"/>
            </form>
        </div>
    </div>

//提交登錄
function SubmitLogin() {
    //判斷用戶名是否為空
    if (!loginForm.username.value) {
        alert("請輸入用戶姓名！");
        loginForm.username.focus();
        return false;
    }

    //判斷密碼是否為空
    if (!loginForm.password.value) {
        alert("請輸入登錄密碼！");
        loginForm.password.focus();
        return false;
    }
    return true;
}
