Spring Boot似乎看不到我的web安全配置

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

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 定义安全规则
        http
            .authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/user/**").hasAnyRole("USER", "ADMIN")
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .and()
            .logout();
    }
    
    // 其他配置...
}
