Question

我有一个简单的Spring Rest服务设置来处理我在DB中的一些JSON对象。我有两个申请;一个希望保存该数据，另一个希望将数据本地请求/存储到其数据库。使用的对象是两个应用程序都可以访问的共享Jar，因此他们知道结构，期望等。

当我运行数据请求时，我可以看到它进入，但是一些数据已经在JSON中被删除了。我在源系统的最后一个返回点设置了断点，当数据存在（从数据库中拉出）并准备好返回时，它就完好无损。一旦它通过邮递员或我的第二个应用程序以任何形式通过电汇，一些字段已被消隐。

编辑：为了便于阅读，发布了一些简化了特定名称的代码

//------------------The Data "Source"------------------------------
//The source service that serves the content
@ResponseBody
@RequestMapping(value = { "/json/listObjectA" }, method = RequestMethod.GET)
public List<ObjectA> listAllObjectA() {
    List<ObjectA> allObjectA = ObjectA
            .getAll(thisApplicationContext);
    return allObjectA; //a breakpoint here shows the data as expected
    //the data in the DB is correct in source, confirmed.
}


//------------------The Requesting "Target"-----------------------------
//trying to get that data, setting up a baseURL for the service works
//when using this block of code with debuggers on, it reaches the source above.
RestTemplate rest = new RestTemplate();
ResponseEntity<ObjectA[]> sfResponse = rest.getForEntity(
coreBaseLocation+"json/listObjectA",
                ObjectA[].class);
ObjectA[] sfList = sfResponse.getBody();
// right here debugging, the list has the correct number, but some of the data is missing
for (ObjectA sf: sfList) {
    sf.setId(null); //clear the local id, a uuid is persisting
    sf.save(thisApplicationContext);
}

//------------------The data class------------------------------
@Entity
public class ObjectA{
...
protected String ObjectBUuid;
protected String ObjectCUuid;
...
// basic POJO getters/setters/constructor etc. nothing fancy

另外作为参考，ObjectA是一个简单的＆＃34;加入＆＃34; ObjectB和ObjectC之间的对象。一个简单的连接表并不起作用，因为我存储了很多关于该关联的元数据，这些数据与此不相关但是出于商业原因需要。

//Here is a copy of the "response" from Postman hitting that json url.
//again, in debug before this is sent back the data looks correct with the Uuids populated (like in the DB)
[
{
  "id": 1, //local id of the ObjectA
  "uuid": "1464d8dc-0281-4850-a51d-a375f7a2fd04",  //ObjectA's uuid
  ... metadata stuff ...
  // end of obj., no reference to the ObjectB/C uuids at all in the returned obj.
}, // more data here matching the number I expect from the DB and the source debug breakpoint, just with the reference uuid missing.

返回时弹簧休息丢弃数据
