Cannot resolve method 'antMatchers()' in AuthorizationManagerRequestMatcherRegistry

Question

I am currently following the Spring Documentation and some tutorials on Web Security. But now I have a problem, that I can't call the method antMatchers. This is the error I'm getting when building the project:

java: cannot find symbol
  symbol:   method antMatchers(java.lang.String)
  location: variable requests of type org.springframework.security.config.annotation.web.configurers.AuthorizeHttpRequestsConfigurer<org.springframework.security.config.annotation.web.builders.HttpSecurity>.AuthorizationManagerRequestMatcherRegistry

In terms of my understanding, I should be able to use this method, so I can permit or not permit HTTP Requests to a certain URL. So my question is, why can't I use the antMatchers() method?

SecurityConfiguration class:

package de.gabriel.vertretungsplan.security;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
                .authorizeHttpRequests((requests) -> requests
                        .antMatchers("/vertretungsplan").hasAnyRole("SCHUELER", "LEHRER", "VERWALTUNG")
                        .anyRequest().authenticated()
                )
                .formLogin((form) -> form
                        .loginPage("/login")
                        .permitAll()
                )
                .logout((logout) -> logout.permitAll());

        return http.build();
    }

}

Answer 1

In antMatchers() (as well as mvcMathcers() and regexMatchers()) have been deprecated and removed with Spring Security 6.0. Thus, you can't use them in a Spring Boot 3 project.

Have a look at this link if you wonder what was the rationale behind this change: Deprecate trailing slash match.

Overloaded method requestMatchers() was provided as a uniform mean for securing requests. It facilitates all the functionality of the configuration methods that have been removed from the API.

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
        .authorizeHttpRequests(requests -> requests
            .requestMatchers("/vertretungsplan").hasAnyRole("SCHUELER", "LEHRER", "VERWALTUNG")
            .anyRequest().authenticated()
        )
        .formLogin(form -> form
            .loginPage("/login")
            .permitAll()
        )
        .logout(logout -> logout
            .permitAll());
    
    return http.build();
}

Answer 2

.requestMatchers("/assets/**").permitAll()

works for me But make sure you check your link is the same with where you insert

for example

If you use:
  <link href="assets/css/style.css" rel="stylesheet">
  
Here you need to use:
  .requestMatchers("/assets/**").permitAll()
  
If you use:
  <link href="resources/**" rel="stylesheet">
  
Here you need to use:
  .requestMatchers("/resources/**").permitAll()
