拦截当网关

配置zuul.routes当我配置bootstrap.properties，我TestHandlerInterceptor在gareway应用程序定义是没有得到调用匹配/注册的所有请求zuul路线，但它被调用不获取调用所有其它请求TestHandlerInterceptor.preHandle是越来越成功处理拦截当网关

bootstrap.properties

zuul.routes.registration-service.path=**registrations** 
zuul.routes.registration-service.service=registration-service

TestHandlerInterce ptor.java

public class TestHandlerInterceptor implements HandlerInterceptor { 


@Autowired 
AuthenticationService authenticationService; 


@Override 
public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception { 

    System.out.println(" ********* preHandle ********"); 
    boolean result = true; 
    if(!authenticationService.isAuthenticated(httpServletRequest)){ 
     result = false; 
     httpServletResponse.setStatus(401); 
    } 


    return result; 
} 

@Override 
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception { 

} 

@Override 
public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception { 

} 
}

GatewayApplication.java

@EnableZuulProxy 
@SpringBootApplication 
@EnableDiscoveryClient 
public class GatewayApplication{ 

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

@Bean 
public WebMvcConfigurerAdapter adapter() { 
    return new WebMvcConfigurerAdapter() { 
     @Override 
     public void addInterceptors(InterceptorRegistry registry) { 
      registry.addInterceptor(new TestHandlerInterceptor()); 
      super.addInterceptors(registry); 
     } 
    }; 
} 
} 


@RestController 
class Orchestration { 
@LoadBalanced 
@Autowired 
    private RestTemplate restTemplate ; 

@RequestMapping("/api/test") 
public @ResponseBody 
Collection<Registration> getRegistrations(){ 
    ResponseEntity<Resources<Client>> resourceResponseEntity = this.restTemplate.exchange("http://registration-service/registrations", HttpMethod.GET,null, ptr); 

} 

}

的TestHandlerInterceptor.preHandle执行本地主机：1122/API /测试，但它没有得到所谓的本地主机：1122 /注册

我试图在我的拦截器中添加一个AuthenticationService，它将在请求任何子资源之前执行所有无状态身份验证（使用api密钥）。

我试图ZuulFilter实现和MyZuulFilter.run（）是呼吁所有本地主机：1122 /注册请求，但不是本地主机：1122/API /测试

如何配置拦截的方式，它被别的

的pom.xml

<parent> 
    <groupId>org.springframework.cloud</groupId> 
    <artifactId>spring-cloud-starter-parent</artifactId> 
    <version>Angel.SR6</version> 
</parent>

尝试作案前执行fying WebMvcconfigurator豆如下

@Bean 
public WebMvcConfigurerAdapter adapter() { 
    return new WebMvcConfigurerAdapter() { 
     @Override 
     public void addInterceptors(InterceptorRegistry registry) { 
      registry.addInterceptor(new TestHandlerInterceptor(()).addPathPatterns("/**") 
     } 
    }; 
} 
}

也改变了自举属性： -

zuul.routes.registration-service.path=/registrations/** 
zuul.routes.registration-service.service=registration-service

添加addPathPatterns（“/ **”）没有给预期的结果..可能是我做错了什么 – Ravi

更新的答案，也许你需要改变的路径模式。你能否通过zuul登录注册服务？ –

已经有zuul.routes.registration-service.path = **注册** zuul.routes.registration-service.service =引导程序中的注册服务。我可以通过zuul打这个服务，但是我的拦截器没有被调用。现在我已经在ZuulFilter.run（）中重复了我的身份验证（使用api键）代码。现在代码存在两个地方Filter和Interceptor，我试图避免 – Ravi

看看这个。 HandlerInterceptorAdapter and Zuul Filter

@Configuration 
@RequiredArgsConstructor 
public class ZuulHandlerBeanPostProcessor extends InstantiationAwareBeanPostProcessorAdapter { 

    private MyInterceptor myInterceptor = new MyInterceptor(); 

    @Override 
    public boolean postProcessAfterInstantiation(final Object bean, final String beanName) throws BeansException { 
     if (bean instanceof ZuulHandlerMapping) { 
      ZuulHandlerMapping zuulHandlerMapping = (ZuulHandlerMapping) bean; 
      Object[] objects = {oauth2Interceptor}; 
      zuulHandlerMapping.setInterceptors(objects); 
     } 
     return super.postProcessAfterInstantiation(bean, beanName); 
    } 
}
