*/
@EnableWebSecurity
public class MySecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// super.configure(http);
//Authorization rules for custom requests
http.authorizeRequests().antMatchers("/").permitAll()//Everyone has access to the root directory
.antMatchers("/level1/**").hasRole("VIP1")//Access to requests under "/ level1" requires "VIP1" permission
.antMatchers("/level2/**").hasRole("VIP2")//Access to requests under "/ level2" requires "VIP2" permission
.antMatchers("/level3/**").hasRole("VIP3");//Access to requests under "/ level3" requires "VIP3" permission
//Turn on the automatically configured login function. If you do not have permission, you will come to the login page
http.formLogin().loginPage("/userlogin").loginProcessingUrl("/login").usernameParameter("user").passwordParameter("pwd");
//Turn on the automatically configured logout function. Accessing / logout means that the user logs off, clears the session, and returns to the login page by default after logout
http.logout().logoutSuccessUrl("/");
//Turn on remember me
http.rememberMe().rememberMeParameter("remember");
}
/**

* @param auth
* @throws Exception
*/
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
//super.configure(auth);
auth.inMemoryAuthentication().withUser("zhangsan").password("123456").roles("VIP1","VIP2","VIP3")
.and().withUser("lisi").password("123456").roles("VIP1");
}
}
3. Customize Thymeleaf page
1) introduction of safety labels
<html xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">2) judge whether it has been certified
<! -- if not certified -- > < div sec: authorize = "! Isauthenticated()" > show uncertified content < / div > <! -- if certified -- > < div sec: authorize = "isauthenticated()" > display authentication content < / div >
3) get user name and role
<!--Get user name--> <span sec:authentication="name"></span> <!--Getting roles--> <span sec:authentication="principal.authorities"></span>
4) judge whether you have a role
<div sec:authorize="hasRole('VIP1')"></div>
