攔截當網關

配置zuul.routes當我配置bootstrap.properties，我TestHandlerInterceptor在gareway應用程序定義是沒有得到調用匹配/註冊的所有請求zuul路線，但它被調用不獲取調用所有其它請求TestHandlerInterceptor.preHandle是越來越成功處理攔截當網關

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執行本地主機：1122/API /測試，但它沒有得到所謂的本地主機：1122 /註冊

我試圖在我的攔截器中添加一個AuthenticationService，它將在請求任何子資源之前執行所有無狀態身份驗證（使用api密鑰）。

我試圖ZuulFilter實現和MyZuulFilter.run（）是呼籲所有本地主機：1122 /註冊請求，但不是本地主機：1122/API /測試

如何配置攔截的方式，它被別的

的pom.xml

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

嘗試作案前執行fying WebMvcconfigurator豆如下

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

也改變了自舉屬性： -

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

添加addPathPatterns（「/ **」）沒有給預期的結果..可能是我做錯了什麼 – Ravi

更新的答案，也許你需要改變的路徑模式。你能否通過zuul登錄註冊服務？ –

已經有zuul.routes.registration-service.path = **註冊** zuul.routes.registration-service.service =引導程序中的註冊服務。我可以通過zuul打這個服務，但是我的攔截器沒有被調用。現在我已經在ZuulFilter.run（）中重複了我的身份驗證（使用api鍵）代碼。現在代碼存在兩個地方Filter和Interceptor，我試圖避免 – Ravi

看看這個。 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); 
    } 
}
