第一节 Spring Security 简介
Spring 是一个非常流行和成功的 Java 应用开发框架。Spring Security 基于 Spring 框架，提供了一套 Web 应用安全性的完整解决方案。一般来说，Web 应用的安全性包括用户认证（Authentication）和用户授权（Authorization）两个部分。
-
用户认证指的是验证某个用户是否为系统中的合法主体，也就是说用户能否访问该系统。用户认证一般要求用户提供用户名和密码。系统通过校验用户名和密码来完成认证过程。
-
用户授权指的是验证某个用户是否有权限执行某个操作。在一个系统中，不同用户所具有的权限是不同的。比如对一个文件来说，有的用户只能进行读取，而有的用户可以进行修改。一般来说，系统会为不同的用户分配不同的角色，而每个角色则对应一系列的权限。
对于上面提到的两种应用情景，Spring Security 框架都有很好的支持。在用户认证方面，Spring Security 框架支持主流的认证方式，包括 HTTP 基本认证、HTTP 表单验证、HTTP 摘要认证、OpenID 和 LDAP 等。在用户授权方面，Spring Security 提供了基于角色的访问控制和访问控制列表（Access Control List，ACL），可以对应用中的领域对象进行细粒度的控制。
第二节 Spring Security 核心组件
1. Authentication 认证
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#aa5500">//这个接口的实现类都是Token，称为票据，UsernamePasswordAuthenticationToken</span>
<span style="color:#aa5500">//我们自定义实现就可以叫MobileCodeAuthenticationToken</span>

<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 认证凭据，可能是密码，也可能是验证码，也可能是其他认证凭据</span>
<span style="color:#aa5500">*/</span>
<span style="color:#008855">Object</span> <span style="color:#000000">getCredentials</span>();
<span style="color:#aa5500">/**</span>

<span style="color:#aa5500">*/</span>
<span style="color:#008855">Object</span> <span style="color:#000000">getDetails</span>();
<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 如果通过认证，则返回的是包含（用户名和密码）或者（手机号和验证码）等的对象；如果认证不通过，</span>
<span style="color:#aa5500">* 则返回的是用户名或者手机号等。</span>
<span style="color:#aa5500">*/</span>
<span style="color:#008855">Object</span> <span style="color:#000000">getPrincipal</span>();
<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 是否认证通过</span>
<span style="color:#aa5500">*/</span>
<span style="color:#008855">boolean</span> <span style="color:#000000">isAuthenticated</span>();
<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 修改认证状态</span>
<span style="color:#aa5500">*/</span>
<span style="color:#008855">void</span> <span style="color:#000000">setAuthenticated</span>(<span style="color:#008855">boolean</span> <span style="color:#000000">isAuthenticated</span>) <span style="color:#770088">throws</span> <span style="color:#000000">IllegalArgumentException</span>;
}</span></span>Authentication接口就是用来携带认证信息的。认证信息包括用户身份信息，密码，及权限列表等
2. UsernamePasswordAuthenticationFilter
账号密码认证过滤器，用于认证用户信息，认证方式是由 AuthenticationManager 接口提供。
3. AuthenticationManager
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">interface</span> <span style="color:#0000ff">AuthenticationManager</span> {
<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 尝试认证传递过来的认证信息，如果认证成功，则会修改认证信息的状态。否则，则会抛出异常</span>
<span style="color:#aa5500">*/</span>
<span style="color:#000000">Authentication</span> <span style="color:#000000">authenticate</span>(<span style="color:#000000">Authentication</span> <span style="color:#000000">authentication</span>) <span style="color:#770088">throws</span> <span style="color:#000000">AuthenticationException</span>;
}</span></span>认证管理器，是认证相关的核心接口，也是发起认证的出发点。实际业务中可能根据不同的信息进行认证，所以Spring推荐通过实现 AuthenticationManager 接口来自定义自己的认证方式。Spring 提供了一个默认的实现 ProviderManager。
4. ProviderManager
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">class</span> <span style="color:#0000ff">ProviderManager</span> <span style="color:#770088">implements</span> <span style="color:#000000">AuthenticationManager</span>, <span style="color:#000000">MessageSourceAware</span>, <span style="color:#000000">InitializingBean</span> {

<span style="color:#aa5500">//省略其他内容</span>
}</span></span>认证提供者管理器，该类中维护了一个认证提供者列表，只要这个列表中的任何一个认证提供者提供的认证方式认证通过，认证就结束。
5. AuthenticationProvider
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">interface</span> <span style="color:#0000ff">AuthenticationProvider</span> {

}</span></span>认证提供者，这是一个接口，具体如何认证，就看如何实现该接口。Spring Security 提供了 DaoAuthenticationProvider 实现该接口，这个类就是使用数据库中数据进行认证。
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">class</span> <span style="color:#0000ff">DaoAuthenticationProvider</span> <span style="color:#770088">extends</span> <span style="color:#000000">AbstractUserDetailsAuthenticationProvider</span> {

}</span></span>用户的详细信息，主要用于登录认证。
8. SecurityContextHolder
SecurityContextHolder 是最基本的对象，它负责存储当前 SecurityContext 信息。SecurityContextHolder默认使用 ThreadLocal 来存储认证信息，意味着这是一种与线程绑定的策略。在Web场景下的使用Spring Security，在用户登录时自动绑定认证信息到当前线程，在用户退出时，自动清除当前线程的认证信息。
9. SecurityContext
SecurityContext 负责存储认证通过的用户信息（Authentication对象），保存着当前用户是什么，是否已经通过认证，拥有哪些权限等等。
10. AuthenticationSuccessHandler
AuthenticationSuccessHandler 主要用于认证成功后的处理，比如返回页面或者数据。
11. AuthenticationFailureHandler
AuthenticationFailureHandler 主要用于认证失败后的处理，比如返回页面或者数据。
12. AccessDecisionManager
AccessDecisionManager 主要用于实现权限，决定请求是否具有访问的权限。
13. AccessDeniedHandler
AccessDeniedHandler 主要用于无权访问时的处理
第三节 Spring Security 工作流程
1. DelegatingFilterProxy
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">class</span> <span style="color:#0000ff">DelegatingFilterProxy</span> <span style="color:#770088">extends</span> <span style="color:#000000">GenericFilterBean</span> {}
<span style="color:#770088">public</span> <span style="color:#770088">abstract</span> <span style="color:#770088">class</span> <span style="color:#0000ff">GenericFilterBean</span> <span style="color:#770088">implements</span> <span style="color:#000000">Filter</span>, <span style="color:#000000">BeanNameAware</span>, <span style="color:#000000">EnvironmentAware</span>,
<span style="color:#000000">EnvironmentCapable</span>, <span style="color:#000000">ServletContextAware</span>, <span style="color:#000000">InitializingBean</span>, <span style="color:#000000">DisposableBean</span> {}</span></span>由上面的类定义可以看出，DelegatingFilterProxy是一个 Filter，同时，也是一个InitializingBean。
<span style="background-color:#f8f8f8"><span style="color:#333333"><span style="color:#770088">public</span> <span style="color:#770088">interface</span> <span style="color:#0000ff">InitializingBean</span> {
<span style="color:#aa5500">/**</span>
<span style="color:#aa5500">* 当Bean的所有属性设置后由包含的BeanFactory调用，而BeanFactory就是用来创建bean的，换言之，就是将Bean纳入Spring IOC容器</span>
<span style="color:#aa5500">*/</span>
<span style="color:#008855">void</span> <span style="color:#000000">afterPropertiesSet</span>() <span style="color:#770088">throws</span> <span style="color:#000000">Exception</span>;
}</span></span>实现了InitializingBean接口的类，在创建对象并完成属性设置后，会被纳入Spring IOC 容器管理。如果DelegatingFilterProxy在web.xml中配置，那么，在容器启动时就会实例化该Filter，然后完成初始化，随后被纳入 Spring IOC 容器管理。这样就相当于与 Spring 完成整合。
而 DelegatingFilterProxy 由 spring web 提供，与 Spring Security 无关。那么 DelegatingFilterProxy 到底有什么作用呢？
其作用是代理真正的Filter实现类
DelegatingFilterProxy 如何知道其所代理的Filter是哪个呢？
这是通过其自身的targetBeanName的属性来确定的，通过该名称，DelegatingFilterProxy可以从WebApplicationContext中获取指定的 bean 作为代理对象。该属性可以通过在web.xml 中定义 DelegatingFilterProxy 时通过 init-param 来指定，如果未指定，则将取其在web.xml中声明时定义的名称作为 targetBeanName 的值。

<span style="color:#117700"></</span><span style="color:#117700">filter-mapping</span><span style="color:#117700">></span></span></span>2. FilterChainProxy
使用Spring Security时，DelegatingFilterProxy 代理的就是一个 FilterChainProxy。当我们使用基于Spring Security的NameSpace进行配置时，系统会自动为我们注册一个名为 springSecurityFilterChain 类型为 FilterChainProxy 的 Bean，这也是为什么我们在使用 Spring Security 时需要在 web.xml 中声明一个 name 为 springSecurityFilterChain 的 DelegatingFilterProxy 的 Filter 了。
FilterChainProxy 有什么作用呢？
一个 FilterChainProxy 中可以包含有多个 FilterChain，但是某个请求只会对应一个 FilterChain，而一个 FilterChain 中又可以包含有多个 Filter。
而 Spring Security 底层正是通过一系列的 Filter 来工作的。具体详情如下：
2.1 WebAsyncManagerIntegrationFilter
将Security上下文与SpringWeb中用于处理异步请求映射的WebAsyncmanager进行集成
2.2 SecurityContextPersistenceFilter
在每次请求处理之前将该请求相关的安全上下文信息加载到SecurityContextHolder中，然后在该次请求处理完成之后麻将SecurityContextHolder中关于这次请求的信息存储的‘仓储’中，然后将SecurityContextHolder中的信息清除，例如在Session中维护一个用户的安全信息就是这个过滤器处理的
2.3 HeaderWriterFilter
用于将头信息加入响应中
2.4 CsrfFilter
用于处理跨站请求伪造
2.5 LogoutFilter
用于处理退出登录
2.6 UsernamePasswordAuthenticationFilter
[重点]
用于处理基于表单的登录请求，从表单中获取用户名和密码，默认情况下处理来自/login的请求，从表单中获取用户名和密码， 默认使用表单name值为username和password，这两个值可以通过这个过滤器的usernaemparamter个passwordParameter连个参数的值进行修改
2.7 DefaultLoginPageGeneratingFilter
如果没有配置登陆页面，那系统初始化就会配置这个过滤器。并且用于在需要进行登陆时生成一个登陆表单页
2.8 BasicAuthenticationFilter
检测和处理http basic认证
2.9 RequestCacheAwareFilter
用于处理请求的缓存
2.10 SecurityContextHolderAwareRequestFilter
主要包装请求对象request
2.11 AnonymousAuthenticationFilter
检测SecurityContextHolder中是否存在Authentication对象，如果不存在为其提供一个匿名Authentication
2.12 SessionManagementFilter
管理session的过滤器
2.13 ExceptionTranslationFilter
处理AccessDeniedException和AuthenticationException异常
2.14 FilterSecurityInterceptor
可以看作过滤器链的出口
2.15 RememberMeAuthenticationFilter
当用户没有登录而直接访问资源时，从cookie中找出用户的信息，如果SpringSecurity能够识别出用户提供remember me cookie ，用户将不必填写用户名和密码，而是直接登录进入系统，该过滤器默认从不开启

1.12 核心流程梳理
登录请求被 UsernamePasswordAuthenticationFilter 拦截，该拦截器尝试认证，认证过程中调用 AuthenticationManager进行认证。AuthenticationManager进行认证时，将该认证管理器中的所有认证提供器遍历一遍，遍历过程中，首先检测认证提供器是否支持认证的票据类型，如果支持，则认证提供器开始进行认证。认证提供器认证过程中会调用 UserDetailsService 获取用户信息，然后进行信息比对，如果正确，则返回一个认证通过的票据。所有认证提供器中，只要任意一个认证提供器认证通过，则表示认证成功。
