为什么int-http：outbound-gateway的JSON有效负载会给出400 Bad Request？
以下请求在Chrome Rest客户端上正常工作，inObjgateway中指定了3个标头，Obj的JSON值
public class Obj {
@JsonProperty("phone")
private String phoneNo;
@JsonProperty("orderNumber")
private String orderNmb;
}

任何指示赞赏！
答案 0 :(得分：1)
这样的问题太笼统了;你需要提供更多细节。
这要求您使用一些基本的调试技巧。
第1步：查看服务器端日志，看看它在抱怨什么。
如果这不能产生解决方案，
第2步：比较“好”和“坏”请求的网络监视器跟踪，并找出它们之间的不同之处。如果您看到有什么不同，并且无法弄清楚如何配置网关来复制“好”请求，那么请回到这里，然后回答具体的问题。
您可以使用Wireshark或eclipse TCP / IP Monitor等获取网络跟踪。
修改
从跟踪中可以看出，您正在进行两次JSON转换。
删除object-to-json-transformer，然后让出站网关进行转换。
