Spring拦截器与@RepositoryRestResource不兼容

及

最后，使用@RepositoryRestController将实体显示为REST，如下所示：

@SpringBootConfiguration
public class AnnotationSecurityConfiguration implements WebMvcConfigurer {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new TestInterceptor()).addPathPatterns("/api/**");
    }
}

但是拦截器没有被调用

由于REST资源是通过@RepositoryRestController管理的Spring数据REST，因此不会调用拦截器。但是如果我使用@RestController编写REST资源，它将工作

如何使拦截器与@RepositoryRestController一起工作？

您必须将

TestInterceptor

添加为bean，并使用

@Autowired

将其激活，只需添加以下更改即可将拦截器注册到拦截器注册表中：

curl -X GET https://localhost:8080/api/v1/users 

HandlerInterceptor：

@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/**");
    }

作为示例，我已将“/api/”更改为“/”，下面是一个日志示例：

@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;
        }
}

我通过以下配置/spring boot应用程序使它工作（在

/

上下文路径上，以及一个简单的

用户

类spring boot v2.4.2上）：

2021-02-13 00:36:31.075  INFO 14340 --- [on(2)-127.0.0.1] o.s.web.servlet.DispatcherServlet        : Completed initialization in 22 ms

我使用了一个简化的：

...
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");
        }
    }
}

@RepositoryRestResource
公共接口UserRepository扩展了JpaRepository，JpaSpecificationExecutor{}

您是否尝试过使用

@Component

注释对

TestInterceptor

进行注释？刚刚尝试过，如果容器扫描和管理了

TestInterceptor

，那么您应该将其注入，而不是执行

新建TestInterceptor（）

。这样行吗<代码>@Autowired TestInterceptor TestInterceptor和

注册表.addInterceptor（testInterceptor）.addPathPathPatterns（“/api/**”）刚刚尝试了autowire，同样的事情确保testinterceptor bean正在创建并注入到配置bean中？在第
行注册表.addInterceptor…
之前，
断言testInterceptor！=无效？我不想显得粗鲁，但您至少应该通过引用来确认此解决方案的原始作者…您的代码中甚至有错误的注释，因为混淆了我在上面的注释中链接的两个答案：
