如何灵活配置Spring WebSecurity

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 配置安全规则
        http
            .authorizeRequests()
                .antMatchers("/public/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }
    
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // 配置用户认证
        auth
            .inMemoryAuthentication()
                .withUser("user")
                .password("{noop}password")
                .roles("USER");
    }
}
