五、Spring Boot与安全

安全、Spring Security

一、安全

Spring Security是针对Spring项目的安全框架,也是Spring Boot底层安全模 块默认的技术选型。他可以实现强大的web安全控制。对于安全控制,我们仅 需引入spring-boot-starter-security模块,进行少量的配置,即可实现强大的 安全管理。

几个类:
WebSecurityConfigurerAdapter:自定义Security策略 AuthenticationManagerBuilder:自定义认证策略
@EnableWebSecurity:开启WebSecurity模式

  • 应用程序的两个主要区域是“认证”和“授权”(或者访问控制)。 这两个主要区域是Spring Security 的两个目标。
  • “认证”(Authentication),是建立一个他声明的主体的过程(一 个“主体”一般是指用户,设备或一些可以在你的应用程序中执行动 作的其他系统)。
  • “授权”(Authorization)指确定一个主体是否允许在你的应用程序 执行一个动作的过程。为了抵达需要授权的店,主体的身份已经有认 证过程建立。
  • 这个概念是通用的而不只在Spring Security中。

二、Web&安全

  1. 登陆/注销
    – HttpSecurity配置登陆、注销功能
  2. Thymeleaf提供的SpringSecurity标签支持
    – 需要引入thymeleaf-extras-springsecurity4
    – sec:authentication=“name”获得当前用户的用户名
    – sec:authorize=“hasRole(‘ADMIN’)”当前用户必须拥有ADMIN权限时才会显示标签内容
  3. remember me
    – 表单添加remember-me的checkbox
    – 配置启用remember-me功能
  4. CSRF(Cross-site request forgery)跨站请求伪造
    – HttpSecurity启用csrf功能,会为表单添加_csrf的值,提交携带来预防CSRF;
