在spring boot中应用@PreAuthority后自动装配服务出错

我已经实施了存储TaxiParks的服务。一切正常。但是我应用了@PreAuthorize（＆＃34; hasAuthority（＆＃39; SuperAdmin＆＃39;）＆＃34;），服务层无法自动装配。我的应用程序无法使用此服务。如何保留使用服务层的安全请求？我删除@PreAuthority它再次运作良好。谁能解释一下？

服务层Impl 

@Service()
public class TaxiParkServiceImpl implements TaxiParkService{

    @Autowired
    private TaxiParkRepository repository;

    @Override
    public void saveOrUpdate(TaxiParkForm form) {
        TaxiParkEntity entity = new TaxiParkEntity();
        entity.setAddress(form.getAddress());
        entity.setInn(form.getInn());
        entity.setMfo(form.getMfo());
        entity.setPhone(form.getPhone());
        entity.setTitle(form.getTitle());
        entity.setTransitAccountNumber(form.getTransitAccountNumber());
        entity.setDirector(form.getDirector());
        repository.save(entity);
    }

}

myController的：

@Controller
public class TaxiParkController {

    @Autowired
    private TaxiParkService taxiParkService;

    ***@PreAuthorize("hasAuthority('SuperAdmin')")***
    @RequestMapping(value = "/admin/addPark.html", method = RequestMethod.POST)
    private String addPark(@Valid @ModelAttribute("TaxiParkForm") TaxiParkForm form, BindingResult bindingResult, Model model) {
        if (bindingResult.hasErrors()) {
            return "admin/taxi_park_form";
        }
        **taxiParkService.saveOrUpdate(form);**
        return "redirect:admin/taxi_parks";
    }
}

WebSecurityConfig：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
     ......
}

错误讯息：

请将addPark方法更改为公开

对于Kotlin用户：如果您的方法不是from pyspark.sql.functions import pandas_udf, PandasUDFType import numpy as np import pandas as pd df = spark.createDataFrame(zip(["name_"+str(i) for i in range(1,6)], [11.23, 14.57, 2.21, 8.76, 18.71]), ["Name", "Score"]) bin_array = np.array([0, 5, 10, 15, 20]) @pandas_udf('double', PandasUDFType.SCALAR) def find_nearest(value): res = bin_array[np.newaxis, :] - value.values[:, np.newaxis] ret_vals = [bin_array[np.argmin(np.abs(i))] for i in res] return pd.Series(ret_vals) df.withColumn('v2', find_nearest(df.Score)).show() ，则可能会出现此错误。默认情况下，Kotlin类和方法是最终的，因此将其打开很重要。
