上一片文章实现了用户验证 查看
当用户成功登录后，关闭浏览器，重新打开浏览器访问http://localhost:8080，页面会跳转到登录页，因为浏览器的关闭后之前的登录已失效
Shiro提供了Remember Me的功能，用户的登录状态不会因为浏览器的关闭而失效，直到Cookie过期
1.修改ShiroConfig
（1）添加
/** * cookie对象 * @return */ public SimpleCookie rememberMeCookie() { // 设置cookie名称，对应login.html页面的<input type="checkbox" name="rememberMe"/> SimpleCookie cookie = new SimpleCookie("rememberMe"); // 设置cookie的过期时间，单位为秒，这里为一天 cookie.setMaxAge(86400); return cookie; } /** * cookie管理对象 * @return */ public CookieRememberMeManager rememberMeManager() { CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager(); cookieRememberMeManager.setCookie(rememberMeCookie()); // rememberMe cookie加密的密钥 cookieRememberMeManager.setCipherKey(Base64.decode("4AvVhmFLUs0KTA3Kprsdag==")); return cookieRememberMeManager; }
（2）将cookie管理对象设置到SecurityManager
修改securityManager()为
@Bean public SecurityManager securityManager() { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(myShiroRealm()); securityManager.setRememberMeManager(rememberMeManager());//新加 return securityManager; }
（3）改权限配置
将ShiroFilterFactoryBean的
filterChainDefinitionMap.put("/**", "authc")
修改为
filterChainDefinitionMap.put("/**", "user");
说明：
user指的是用户认证通过或者配置了Remember Me记住用户登录状态后可访问
2.修改login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" th:href="@{/css/login.css}" type="text/css"> <link rel="stylesheet" th:href="@{css/iCheck/minimal/blue.css}" type="text/css"> <link rel="stylesheet" th:href="@{css/app.css}" type="text/css"> <script th:src="@{/js/jquery.min.js}"></script> </head> <body> <div class="login-page"> <!-- Form--> <div class="form"> <div class="form-toggle"></div> <div class="form-panel one"> <div class="form-header"> <h1>账户登录</h1> </div> <div class="form-content"> <div class="form-group"> <label>用户名</label> <input type="text" name="account" /> </div> <div class="form-group"> <label>密码</label> <input type="password" name="password" /> </div> <div class="form-group" style="margin: 0px;"> <p> <input type="checkbox" name="rememberMe" /> 记住我</p> </div> <div class="form-group"> <button onclick="login()" id="loginButton">登录</button> </div> </div> </div> </div> </div> </body> <script th:inline="javascript"> var ctx = [[@{/}]]; function login() { var account = $("input[name='account']").val(); var password = $("input[name='password']").val(); var rememberMe = $("input[name='rememberMe']").is(':checked'); $.ajax({ type: "post", url: ctx + "login", data: {"account": account,"password": password,"rememberMe": rememberMe}, dataType: "json", success: function (r) { if (r.code == 0) { location.href = ctx + 'index'; } else { alert(r.msg); } } }); } </script> </html>
3.修改LoginController
@PostMapping("/login")
@ResponseBody
public ResponseBo login(String account, String password, Boolean rememberMe) {
System.out.println(rememberMe);
// 密码MD5加密
password = MD5Utils.encrypt(account, password);
System.out.println(password);
UsernamePasswordToken token = new UsernamePasswordToken(account, password);
rememberMe = rememberMe == null ? false : rememberMe; //null=>false
token.setRememberMe(rememberMe);
//UsernamePasswordToken token = new UsernamePasswordToken(username, password,rememberMe);
// 获取Subject对象
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
if (rememberMe) System.out.println("rememberMe--------");
return ResponseBo.ok();
} catch (UnknownAccountException e) {
return ResponseBo.error(e.getMessage());
} catch (IncorrectCredentialsException e) {
return ResponseBo.error(e.getMessage());
} catch (LockedAccountException e) {
return ResponseBo.error(e.getMessage());
} catch (AuthenticationException e) {
return ResponseBo.error("认证失败！");
}
}
rememberMe选中的时候，Shiro就会帮忙记住用户的登录状态
