是建立一个它声明的主体的过程(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)
证明用户的身份,当用户登录之后,系统来查验用户名和密码,以此来证明你有对应身份,这个过程就是认证。
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
指的是你能够干什么 ,有什么样的访问权限。
WebSecurityConfigurerAdapter:自定义Security策略
AuthenticationManagerBuilder:自定义认证策略
@EnableWebSecurity:开启WebSecurity模式
WebSecurityConfigurerAdapter
需要重写方法
定制请求的授权规则
开启自动配置登录功能 :如果没有登录,没有权限就会到登录页面
开启自动配置的注销功能
http.logout().logoutSuccessUrl("/"); //注销成功之后 ,来到首页
@Override
protected void configure(HttpSecurity http) throws Exception {
//定制请求的授权规则
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("VIP1")
.antMatchers("/level2/**").hasRole("VIP2")
.antMatchers("/level3/**").hasRole("VIP3");
//开启自动配置登录功能
http.formLogin();
//1、/login请求来到登录页
//2、重定向到/login?error 表示登录失败
//3、更多功能
//4、默认post形式的/login代表处理登录
//5、一旦定制loginPage;name loginPage的post请求就是登录
// 开启自动配置的注销功能
//防止网站攻击
http.csrf().disable();
http.logout();
需要重写 方法
, 配置对应的账号密码 以及角色
//定义认证规则
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
.withUser("zhangsan").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP1","VIP2")
.and()
.withUser("lisi").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP2","VIP3")
.and()
.withUser("wangwu").password(new BCryptPasswordEncoder().encode("123456")).roles("VIP1","VIP3");
