如何在spring安全中禁用/oauth/token的GET option端点并仅保留POST选项？

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/oauth/token").denyAll() // 禁用GET请求
                .antMatchers(HttpMethod.OPTIONS, "/oauth/token").denyAll() // 禁用OPTIONS请求
                .antMatchers(HttpMethod.POST, "/oauth/token").permitAll() // 允许POST请求
                .anyRequest().authenticated() // 其他请求需要认证
                .and()
            .csrf().disable(); // 禁用CSRF保护，方便测试
    }
}
