spring-boot 攔截器不攔截

Question

我為我的 spring-boot 應用程序編寫了一個攔截器。 但是當我到達端點時，它執行得很好。攔截器無法攔截我的請求。 我哪里出錯或遺漏了什么？

下面是代碼

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    private static final String PATHS = "/services/api/**";

    @Autowired
    private AuthorizationInterceptor authInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(authInterceptor).addPathPatterns(PATHS);
    }



}

這是攔截器的代碼:::

@Component
public class AuthorizationInterceptor implements HandlerInterceptor {
    private static final Logger LOGGER = LoggerFactory.getLogger(AuthorizationInterceptor.class);
    private static final String MSG_BAD_INPUT = "Very Bad Input";
    private static final int MAX_URI_LENGTH = 4;

    @Override
    public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)
            throws Exception {
        // TODO Auto-generated method stub

    }

    @Override
    public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)
            throws Exception {
        // TODO Auto-generated method stub

    }

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        System.out.println("Inside Prehandle:::::::------->");
        this.checkURILength(request);
        System.out.println("After checking:::::::::::---->");
        return true;

    }

    private void checkURILength(HttpServletRequest request) {
        if (request.getRequestURI().length() > MAX_URI_LENGTH) {
            LOGGER.error("Request URI is too long");
            throw new InvalidInputException(MSG_BAD_INPUT);
        }
    }


}

現在，當我點擊我的 spring-boot 應用程序的端點時，它工作正常

http://localhost:8181/services/api/companies

基本上它根本不調用前處理。 我錯過了什么？？？？

Answer 1

你使用@EnableWebMvc作為

@EnableWebMvc
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
  ...
}

Answer 2

在我的情況下，使用下面答案中描述的MappedInterceptor是有效的。
