Spring Security框架深入解析与实战指南<\/h1>

一、Spring Security概述<\/h2>

Spring Security是Spring家族中的核心安全框架，为Java应用提供全面的安全解决方案。相比同类框架Shiro，它具有以下优势：<\/p>

功能更丰富，覆盖认证授权全流程<\/li>
社区资源更丰富，文档完善<\/li>
与Spring生态无缝集成<\/li>

更适合中大型项目<\/li> <\/ul>

核心功能聚焦于两大安全领域：<\/p>

认证(Authentication)<\/strong>：验证用户身份，确认"你是谁"<\/li>

授权(Authorization)<\/strong>：验证用户权限，确定"你能做什么"<\/li> <\/ol>
二、Spring Security核心架构<\/h2>
Spring Security本质是一个过滤器链，包含多个功能各异的过滤器：<\/p>
核心过滤器组件<\/h3>

UsernamePasswordAuthenticationFilter<\/strong><\/p>

处理表单提交的用户名\/密码登录请求<\/li>
负责认证流程的初始阶段<\/li> <\/ul> <\/li>

ExceptionTranslationFilter<\/strong><\/p>

处理安全异常的核心过滤器<\/li>
专门捕获AccessDeniedException<\/code>和AuthenticationException<\/code><\/li> <\/ul> <\/li>
FilterSecurityInterceptor<\/strong><\/p> 权限校验的最终关卡<\/li> 决定请求是否允许访问受保护资源<\/li> <\/ul> <\/li> <\/ol> 工作原理流程图<\/h3> 客户端请求 → 过滤器链 → 认证过滤器 → 认证管理器 → 认证提供者 → 用户详情服务 → 授权决策 → 资源访问 <\/code><\/pre>
