Question

我为spring-boot应用程序编写了一个拦截器。但是当我点击端点时，它的执行正常。拦截器无法拦截我的请求。我哪里出错了或遗失了什么？

以下是代码

@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);
    }



}

以下是Interceptor :::

的代码

@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);
        }
    }


}

现在当我点击我的spring-boot应用程序的端点时，说它工作正常

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

基本上它根本不叫前手柄。我错过了什么????

您使用@EnableWebMvc作为

吗？

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

spring-boot拦截器没有拦截
