当我输入URL“http：//localhost：8080/registration”时，我希望在Postman（用于临时测试，直到我使用HTML和CSS实现前端和表单）上收到消息“Works”。根据下面发布的代码，这应该会发生。但我收到了405方法不允许错误。
类包的名称为：WebSecurityConfig;

import com.example.finalVersionBookProject.appuser.AppUserService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import  org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@Configuration

this.appUserService = appUserService;

}
