4、在controller包下编写RouterController Controller
public class RouterController {RequestMapping({/,/index,/index.html})public String index(){return index;}RequestMapping(/toLogin)public String toLogin(){return views/login;}RequestMapping(/level1/{id})public String level1(PathVariable(id) int id){return views/level1/id;}RequestMapping(/level2/{id})public String level2(PathVariable(id) int id){return views/level2/id;}RequestMapping(/level3/{id})public String level3(PathVariable(id) int id){return views/level3/id;}
}5、显示结果 首页 登录页 用户认证和授权
1、导入security的starter dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-security/artifactId/dependency
2、在config包下编写一个类去继承WebSecurityConfigurerAdapter并且加上注解EnableWebSecurity EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {//授权Overrideprotected void configure(HttpSecurity http) throws Exception {//请求授权的规则http.authorizeHttpRequests()//首页所有人都可以访问功能页只有对应权限的人才可以访问.antMatchers(/).permitAll().antMatchers(/level1/**).hasRole(vip1).antMatchers(/level2/**).hasRole(vip2).antMatchers(/level3/**).hasRole(vip3);//没有权限默认会到登录页面需要开启登录的页面http.formLogin();}//认证Overrideprotected void configure(AuthenticationManagerBuilder auth) throws Exception {//这些数据正常应该从数据库中读auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder()).withUser(qiu).password(new BCryptPasswordEncoder().encode(123456)).roles(vip1,vip2).and().withUser(root).password(new BCryptPasswordEncoder().encode(123456)).roles(vip1,vip2,vip3).and().withUser(guest).password(new BCryptPasswordEncoder().encode(123456)).roles(vip3);}
}注销 //开启注销功能注销成功之后跳到首页http.logout().logoutSuccessUrl(/); 记住我
前端
input typecheckbox nameremember记住我
后端 //开启记住我功能自定义接受前端传过来的参数http.rememberMe().rememberMeParameter(remember);
原理是保存了一个cookie和一个session默认保存14天 定制登录页
http.formLogin().loginPage(/toLogin);
