我把它修好了 / 上下文路径和一个简单的 User 类，spring boot v2.4.2）和以下config/spring boot应用程序：

...
import org.springframework.web.servlet.handler.MappedInterceptor
...    

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Bean
    public org.springframework.web.servlet.handler.MappedInterceptor myInterceptor() {
        return new MappedInterceptor(
                new String[]{"/users/**"},  // null => maps to any repository/path
                new MyInterceptorImpl()
        );
    }

    private class MyInterceptorImpl implements HandlerInterceptor  {
         @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            System.out.println("preHandle");
            return true;
        }

        @Override
        public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
            System.out.println("postHandle");
        }

        @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
           System.out.println("afterCompletion");
        }
    }
}

我用了一个简化的：

@RepositoryRestResource
public interface UserRepository extends JpaRepository<User, Long>, JpaSpecificationExecutor<User> { }

你必须加上 TestInterceptor 就像一颗豆子，用它来涂油 @Autowired 只需添加以下更改即可将拦截器注册到拦截器注册表中：

@Configuration
@SpringBootApplication
public class DemoApplication extends WebMvcConfigurerAdapter {
    @Autowired
    private TestInterceptor testInterceptor;
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(testInterceptor).addPathPatterns("/api/**");
    }

拦截器：

@Component
public class TestInterceptor implements HandlerInterceptor {

    private static final Logger logger = LoggerFactory.getLogger(TestInterceptor.class);
        @Override
        public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3) throws Exception {
            System.out.println("afterCompletion");
            long startTime = Instant.now().toEpochMilli();
            logger.info("Request URL::" + arg0.getRequestURL().toString() +
                    ":: Start Time=" + Instant.now());
            arg0.setAttribute("startTime", startTime);
        }
        @Override
        public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3) throws Exception {
            System.out.println("postHandle");
        }
        @Override
        public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception {
            System.out.println("preHandle");
            return true;
        }
}

作为示例，我将“/api/”更改为“/”，下面是一个日志示例：
