访问url时,如果未登录时跳转到Login界面,要求用户登陆,如果登陆过返回请求的数据。
效果图
访问数据时,未登录返回login界面
登陆操作
登陆成功进入登出界面
登陆成功后再次访问数据

WebSecurityConfigurerAdapter配置Security信息
1. authorizeRequests() .antMatchers("/user/*").permitAll() .anyRequest().authenticated() 意思代表 /user 不需要进行授权认证,其他都需要认证。
2 .formLogin().loginPage("/login.html").loginProcessingUrl("/signin").successHandler(successHandler).failureHandler(failureHandler) 设置的登陆界面,和登陆的url 以及登陆成功的handler和失败的handler。
3 .usernameParameter("username").passwordParameter("password").permitAll() 用户名和密码的传参数
4 .logout().logoutUrl("/signout").logoutSuccessHandler(logoutSuccessHandler).permitAll(); 登出url ,以及handler
5 .csrf().disable()
