应用程序属性

svrRouteEndpoint=http://somehost.com/endpoint
svrRoute=direct:route
svrHost=host.com
svrApiKey=abc123

服务.java

@Autowired
    private ProducerTemplate template;

    @Value("${svrHost}")
    private String svrHost;

    @Value("${svrApiKey}")
    private String svrApiKey;

public Response process(Request req, Map<String, Object> headers) throws CamelExecutionException {
Response response = template.requestBodyAndHeaders("direct:route", req, headers, Response.class);
return response;
}

 public Map<String, Object> createHeaders(String xWuExternalrefid) {
    Map<String, Object> headers = new HashMap<>();\
    headers.put("host", svrHost);
    headers.put("x-api-key", svrApiKey);
    return headers;
}

现在服务api合同要求只提供3个头和请求体x-api-key，主机和内容类型作为头和requestbody，所以在调用process方法之前，我要在map中包含所有3个头和正确的键值对，同样地创建请求pojo，现在在process方法中调用requestbodyandheaders，它返回原因为httpoperationfailedexception的camelexecutionexception，返回消息：

Exception with the message: {"message": "Forbidden"} and status code : 403.

当我直接从postman中点击服务时，使用完全相同的header值和相同的请求，我得到的响应状态为200ok，但当我从服务中测试它，然后使用camel调用外部服务时就不是了。
无法找出问题的真正原因。
