在出站网关上使用 RestTemplate 进行基本身份验证
Basic Authentication with RestTemplate on outbound gateway
一直在拉我剩下的一点点头发，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 header 作为参数传递给 int:gateway。然后调用 int-http:outbound-gateway。我可以看到 header 以及与远程应用程序的握手，但我从 org.apache.http.impl.client.DefaultHttpClient 得到了 400 Bad Request。我能够使用单独的客户端直接验证和执行请求（即没有 SI）。
我使用 this 解决方案中提到的组件失败。我哪里出错了？
我不喜欢的是对 DefaultHttpClient 的引用，正如其他帖子中提到的那样，它似乎已被弃用。不确定这里有什么选择。我在某处看到提到使用 OkHttp 客户端，但我不确定如何将其与 SI 联系起来。
问题 2:
returns 下面的服务是 ResponseEntity<?>，因为我无法将其转换为域特定类型 (CustSyncResponseVO)。在将 RestTemplate 与 SI 一起使用时，我是否应该期待这种行为，或者我是否可以对 outbound-gateway 响应执行转换？
如有任何帮助，我们将不胜感激！

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 SI 的远程应用程序时，这从 JSON 中解组没有问题中间。我觉得通过 outbound-gateway 发送的双引号 JSON "string" 导致了问题，因为 400 Bad Request 暗示无效 JSON。我来自 SI 网关的请求 object 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() {
}
}
好吧，这是似乎对我有用的解决方案：
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>
之后
<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>
这解决了我在原文 post 中提到的两个问题。消息转换器的顺序很重要。
我在 this post 中找到了解决方案。
一直在拉我剩下的一点点头发，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 header 作为参数传递给 int:gateway。然后调用 int-http:outbound-gateway。我可以看到 header 以及与远程应用程序的握手，但我从 org.apache.http.impl.client.DefaultHttpClient 得到了 400 Bad Request。我能够使用单独的客户端直接验证和执行请求（即没有 SI）。
我使用 this 解决方案中提到的组件失败。我哪里出错了？
我不喜欢的是对 DefaultHttpClient 的引用，正如其他帖子中提到的那样，它似乎已被弃用。不确定这里有什么选择。我在某处看到提到使用 OkHttp 客户端，但我不确定如何将其与 SI 联系起来。
问题 2:
returns 下面的服务是 ResponseEntity<?>，因为我无法将其转换为域特定类型 (CustSyncResponseVO)。在将 RestTemplate 与 SI 一起使用时，我是否应该期待这种行为，或者我是否可以对 outbound-gateway 响应执行转换？
如有任何帮助，我们将不胜感激！

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 SI 的远程应用程序时，这从 JSON 中解组没有问题中间。我觉得通过 outbound-gateway 发送的双引号 JSON "string" 导致了问题，因为 400 Bad Request 暗示无效 JSON。我来自 SI 网关的请求 object 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() {
}
}
好吧，这是似乎对我有用的解决方案：
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>
之后
<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>
这解决了我在原文 post 中提到的两个问题。消息转换器的顺序很重要。
我在 this post 中找到了解决方案。
