Shiro自动登录

第一步 ：配置spring.xml，配置cookieRememberMeManager

<!--创建SecurityManager对象-->
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realm" ref="userRealm" />
        <property name="sessionManager" ref="sessionManager" />
        <property name="cacheManager" ref="cacheManager" />
        <property name="rememberMeManager" ref="cookieRememberMeManager" />
    </bean>

<bean id="cookieRememberMeManager" class="org.apache.shiro.web.mgt.CookieRememberMeManager">
        <property name="cookie" ref="cookie" />
    </bean>
    <bean id="cookie" class="org.apache.shiro.web.servlet.SimpleCookie" >
        <constructor-arg value="rememberMe" />
        <property name="maxAge" value="20000000" />
    </bean>

第二步：修改登录页面

<form action="subLogin" method="post">
        用户名：<input type="text" name="username"><br>
        密码：<input type="password" name="password"><br>
        <input type="checkbox" name="rememberMe">记住登录<br>
        <input type="submit" value="提交">
    </form>

第三步：修改subLogin的Controller，加入token.setRememberMe(Boolean rememberMe)方法

@RequestMapping(path="/subLogin", produces="application/json;charset=utf-8")
    @ResponseBody
    public String subLogin(User user, boolean rememberMe){
        UserRealm userRealm = new UserRealm();
        //构建SecurityManager环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(userRealm);
        //主体提交认证请求
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
        try {
            //是否记住密码
            token.setRememberMe(rememberMe);
            subject.login(token);
        } catch (Exception e){
            return e.getMessage();
        }
        //授权认证
        if (subject.hasRole("admin")){
            return "有admin权限";
        }
        return "无admin权限";
    }

已完成。下次登录时若勾选自动登录，则在cookie存活期间可以免登录。
