第104天学习打卡（SpringBoot 开启记住我功能和定制首页 Shiro）

开启记住我功能 和定制首页

开启记住我功能 和定制首页方法一：

SecurityConfig.java

        //开启了注销功能  跳到首页
        http.logout().logoutSuccessUrl("/");

        //开启记住我功能  本质是一个cookie的实现
        http.rememberMe();

login.html修改的内容：

<div style="text-align: center">
            <h1 class="header">登录h1>
        div>

        <div class="ui placeholder segment">
            <div class="ui column very relaxed stackable grid">
                <div class="column">
                    <div class="ui form">
                        <form th:action="@{/toLogin}" method="post">
                            <div class="field">
                                <label>Usernamelabel>
                                <div class="ui left icon input">
                                    <input type="text" placeholder="Username" name="username">
                                    <i class="user icon">i>
                                div>
                            div>
                            <div class="field">
                                <label>Passwordlabel>
                                <div class="ui left icon input">

                                div>
                            div>
                            <input type="submit" class="ui blue submit button"/>
                        form>
                    div>
                div>
            div>
        div>

方法二

SecurityConfig.java

  http.formLogin().loginPage("/toLogin").loginProcessingUrl("/login");

login.html

    <div class="ui placeholder segment">
            <div class="ui column very relaxed stackable grid">
                <div class="column">
                    <div class="ui form">
                        <form th:action="@{/login}" method="post">
                            <div class="field">
                                <label>Usernamelabel>
                                <div class="ui left icon input">
                                    <input type="text" placeholder="Username" name="username">
                                    <i class="user icon">i>
                                div>
                            div>
                            <div class="field">

Shiro

1.1 什么是Shiro

• Apache Shiro是Java的安全（权限）框架
• Shiro可以非常容易的开发出足够好的应用，其不仅可以用在JavaSE环境，也可以用在JavaEE环境。
• Shiro可以完成，认证，授权，加密，会话4管理，Web集成，缓存等。
• 官网地址：https://shiro.apache.org/

下载地址：https://github.com/apache/shiro

1.2有哪些功能

• Authentication:身份认证、登录、验证用户是不是拥有相应的身份；
• Authorization:授权，即权限验证，验证某个已认证的用户是否拥有某个权限，即判断用户能否进行什么操作。如：验证某个用户是否拥有某个角色，或者细粒度的验证某个用户对某个资源是否具有某个权限！
• Session Manager: 会话管理，即用户登录后就是第一次会话，在没有退出之前，它的所有信息都在会话中；会话可以是普通的JavaSE环境，也可以是Web环境。
• Cryptography:加密，保护数据的安全性，如密码存储到数据库中，而不是明文存储；
• Web Support: Web支持，可以非常容易的集成到Web环境；
• Caching:缓存，比如用户登录后，其用户信息，拥有的角色，权限不必每次去查，这样可以提高效率
• Concurrency:Shiro支持多线程应用的并发验证，即，如在一个线程中开启另一个线程，能把权限自动的传播过去。
• Testing:提高测试支持；
• Run As:允许用户假装为另一个用户（如果他们允许）的身份进行访问；
• Remember Me:记住我，这个是非常常见的功能，即一次登录后，下次再来的话不用登录了。

1.3 Shiro架构（外部）

从外部来看Shiro,即从程序角度来观察如何使用shiro完成工作：

• subject:应用代码直接交互的对象是Subject,也就是说Shiro的对外API核心就是Subject, Subject代表了当前的用户，这个用户不一定是一个具体的人，与当前应用交互的任何东西都是Subject,如网络爬虫，机器人等，与Subject的所有交互都会委托给SecurityManager;Subject其实是一个门面， SecurityManager才是实际的执行者。
• SecurityManager：安全管理者，即所有与安全有关的操作都会与SecurityManager交互，并且它管理所有的Subject，可以看出它是Shiro的核心，它负责与Shiro的其他组件进行交互，它相当于SpringMVC的DispatcherServlet的角色
• Realm:Shiro从Realm获取安全数据（如用户，角色，权限），就是说SecurityManager要验证用户身份，那么它需要从Realm获取相应的用户进行比较；也需要从Realm得到用户相应的角色权限，进行验证用户的操作是否能够进行，可以把Realm看成DataSource

1.4 Shiro架构（内部）

• Subject:任何可以与应用交互的用户；
• Security Manager: 相当于SpringMVC中的DispatcherServlet;是Shiro的心脏，所有具体的交互都通过Security Manager进行控制，它管理着所有的Subject,且负责进行认证，授权，会话及缓存的管理。
• Authenticator:负责Subject认证，是一个扩展点，可以自定义实现，可以使用认证策略（Authentication Strategy）,即什么情况下算用户认证通过了；
• Realm: 可以有一个或者多个的realm,可以任务是安全实体数据源，即用于获取安全实体的，可以用JDBC实现，也可以是内存实现等等，由用户提供；所以一般在应用中都需要实现自己的realm
• SessionManager:管理Session生命周期的组件，而Shiro并不仅仅可以用在Web环境，也可以用在普通的JavaSE环境中
• CacheManager:缓存控制器，用来管理用户，角色，权限等缓存的；因为这些数据基本上很少改变，放到缓存中后可以提高访问的性能
• Cryptography:密码模块，Shiro提高了一些常见的加密组件用于密码加密，解密等
