Given the following code when upgrading Spring Boot version from 2.x to 3.x, e.g. from Spring Boot 2.7.15 (Spring Security 5.7.10) to Spring Boot 3.0.0 (Spring Security 6.0.0):

@Configuration
public class WebSecurityConfig {
	
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    	
        http.authorizeHttpRequests().antMatchers("/signin", "/signup").permitAll()
			.antMatchers("/users/**", "/apps/**").hasAuthority("ADMIN")
			.antMatchers("/myapps/**").hasAuthority("CLIENT")
			.anyRequest().authenticated()
        ...
 
 
        return http.build();
    }
}

You will get the error saying that:

The method antMatchers(String, String) is undefined for the type AuthorizeHttpRequestsConfigurer…

To fix this error, you need to use the requestMatchers()method instead. So update the above code as follows:

http.authorizeHttpRequests().requestMatchers("/signin", "/signup").permitAll()
		.requestMatchers("/users/**", "/apps/**").hasAuthority("ADMIN")
		.requestMatchers("/myapps/**").hasAuthority("CLIENT")
		.anyRequest().authenticated()
...

If you use Spring Boot 3.1.0 or newer (Spring Security 6.1.0 or newer), you should use lambda expression like this:

http.authorizeHttpRequests(
		auth -> auth.requestMatchers("/signin", "/signup").permitAll()
		.requestMatchers("/users/**", "/apps/**").hasAuthority("ADMIN")
		.requestMatchers("/myapps/**").hasAuthority("CLIENT")
		.anyRequest().authenticated()
       )
...

That’s how to fix the error “The method antMatchers() is undefined” in Spring Security. I hope you find this post helpful.
