在出站网关上使用RestTemplate进行基本身份验证

标签： spring-boot spring-integration apache-httpcomponents

拉着我留下的小头发试图让它发挥作用。

问题1 ：

我正在对Spring控制器执行JSON POST。我将Authentication标头作为参数传递给int:gateway。然后调用int-http:outbound-gateway。我可以看到标题以及与远程应用程序的握手，但我从400 Bad Request获得org.apache.http.impl.client.DefaultHttpClient。我能够使用单独的客户端直接验证并执行请求（即没有SI）。

我使用this解决方案中提到的组件失败了。我在哪里错了？

我不喜欢的是对DefaultHttpClient的引用，如其他帖子中所述，它似乎已被弃用。不知道替代方案在这里。在某处我看到了使用OkHttp客户端的提及，但我不确定如何将其与SI连接起来。

问题2 ：

以下服务返回ResponseEntity<?>，因为我无法将其转换为特定于域的类型（CustSyncResponseVO）。在将RestTemplate与SI一起使用时，我是否应该期待这种行为？或者我可以对outbound-gateway响应执行转换吗？

非常感谢任何帮助！

环境

  • Java 1.7
  • Spring Boot 1.3.1.RELEASE

  • HTTP Core v4.3.2和HTTP Client v4.3.5 

        <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>

控制器 

@RequestMapping(value = "/customerSync", method = RequestMethod.POST)
public @ResponseBody CustSyncResponseVO syncCustomer(@RequestBody CustSyncRequestVO customerSyncRequest, 
        @RequestHeader(value = "Authorization") String authorization ) {
    CustSyncResponseVO customerSyncResponse = null;

    customerSyncResponse = customerService.deliver(customerSyncRequest, authorization);

    return customerSyncResponse;
}

package com.uscs.crm.service;

    @Autowired
    private CustomerGateway customerGateway;

    @Override
    public CustSyncResponseVO deliver(CustSyncRequestVO custSyncRequest, @Header(value="Authorization") String authorization) {
        CustSyncResponseVO custSyncResponse = null;     
        //custSyncResponse = customerGateway.deliver(custSyncRequest);
        ResponseEntity<?> responseEntity = null;
        try {
             responseEntity = customerGateway.deliver(custSyncRequest, authorization);
        } catch (Exception e) {
            logger.error("Unable to sync customer request to eWM" , e);
        } 

        return custSyncResponse;
    }


    @Override
    public CustSyncResponseVO link(CustLinkRequestVO linkRequest) {
        throw new UnsupportedOperationException("To be implemented");
    }

}

EDIT1 ：

远程应用程序日志似乎表明将请求解组为预期类型时出现问题：

nested exception is org.codehaus.jackson.map.JsonMappingException: Can not instantiate value of type [simple type, class com.uscs.ewms.mdm.vo.customer.synchronizer.CustomerCreateSyncSubRequestVO] from JSON String; no single-String constructor/factory method (AbstractHandlerExceptionResolver.java:132)

远程应用程序中的控制器和请求类型 

@RequestMapping(value = "/createCustomer", method = RequestMethod.POST, consumes = CONTENTTYPE_APPLICATION_JSON, produces = CONTENTTYPE_APPLICATION_JSON)
public @ResponseBody
CustomerSyncResponseVO createCustomer(HttpServletRequest request, @RequestBody CustomerCreateSyncSubRequestVO customerCreateSyncRequestVO, Principal principal) {

...

}

public class CustomerCreateSyncSubRequestVO {

@JsonProperty("legacyNo")
private String legacyNo;

...

}

远程CustomerCreateSyncSubRequestVO中没有默认构造函数，但是当我将HTTP POST直接发送到没有中间SI的远程应用程序时，这个解组来自JSON没有问题。我觉得通过outbound-gateway发送的双引号JSON“字符串”导致了问题，因为400 Bad Request意味着无效的JSON。来自SI网关的我的请求对象确实有一个没有任何其他注释的默认构造函数：

package com.uscs.crm.model;

public class CustSyncRequestVO {

    private String legacyNo;
...
    public CustSyncRequestVO() {

    }
}

答案 0 :(得分：0)

嗯，这是一个似乎对我有用的解决方案：

<强>之前：

<bean id="restTemplate" name="restTemplate" class="org.springframework.web.client.RestTemplate" autowire-candidate="true">
      <constructor-arg ref="clientHttpRequestFactory" />
  <property name="messageConverters"> 
      <list> 
          <bean  class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
          <bean class="org.springframework.http.converter.FormHttpMessageConverter"/> 
          <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
      </list> 
  </property>
</bean>

<强>后 

<bean id="restTemplate" name="restTemplate" class="org.springframework.web.client.RestTemplate" autowire-candidate="true">
      <constructor-arg ref="clientHttpRequestFactory" />
  <property name="messageConverters"> 
      <list> 
          <bean class="org.springframework.http.converter.FormHttpMessageConverter"/> 
          <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
          <bean  class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
      </list> 
  </property>
</bean>

这解决了我在原帖中提到的两个问题。消息转换器的顺序很重要。

我在this帖子中找到了解决方案。
