spring 特定 api 的引导拦截器不应为所有 api 调用

Question

2 api 暴露在 spring 引导控制器 class 中。我要求只拦截 1 api 并且不应该拦截其他 api。有人可以协助如何做到这一点吗？

下面是代码

public class HeaderValidationInterceptor extends HandlerInterceptorAdapter{
    
    private static final Logger logger = Logger.getLogger(HeaderValidationInterceptor.class);

    //before the actual handler will be executed
    public boolean preHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler)
        throws Exception {
        
        validateHeaderParam(request);
        request.setAttribute("startTime", startTime);
        
        return true;
    }
    
    }

我还有一个配置class来添加拦截器如下

Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

  @Autowired 
  HeaderValidationInterceptor headerValidationInterceptor;

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(headerValidationInterceptor)
    }
    
}

控制器class

@RestController
public class MyController {

    @Autowired
    private ICityService cityService;

    @GetMapping(value = "/cities")
    public List<City> getCities() {

        List<City> cities = cityService.findAll();

        return cities;
    }
    
    
@GetMapping(value = "/cities/{cityId}")
    public City getCityById(@PathVariable("cityId") String cityId) {

        City city = cityService.findCityById(cityId);

        return cities;
    }
}

在拦截器中，您可以检查要拦截的端点的请求 URI。

您可以使用正则表达式来匹配 URI。关注 /cities/{cityId} 端点。

if (request.getRequestURI().matches("(\/cities\/[a-zA-Z0-9]+\/?)")) {
    validateHeaderParam(request);
    request.setAttribute("startTime", startTime);
}

我不确定你的拦截器想要做什么，但对于你的例子，你也可以在你的控制器中做这件事。像这样，

@GetMapping(value = "/cities/{cityId}")
public City getCityById(@PathVariable("cityId") String cityId, HttpServletRequest request) {

    // Here you can use HttpServletRequest and do your validation
    // validateHeaderParam(request);
    // request.setAttribute("startTime", startTime);
    
    City city = cityService.findCityById(cityId);
    return cities;
}

spring boot interceptor for specific api, should not be invoked for all the api's
