date format error

**Describe the bug**
my dto object has a field with LocalDateTime type

` @DateTimeFormat(pattern = "yyyy-MM-dd\'T\'HH:mm:ss.SSS\'Z\'")
@JsonFormat(pattern = "yyyy-MM-dd\'T\'HH:mm:ss.SSS\'Z\'")
private LocalDateTime createTime;`

and i use RestHighLevelClient write to elasticsearch
` UpdateRequest request = new UpdateRequest(index, id);
Gson gson = new GsonBuilder().registerTypeAdapter(LocalDateTime.class,new LocalDateTimeAdapter()).create();
request.doc(gson.toJson(t), XContentType.JSON)
.docAsUpsert(true);
request.scriptedUpsert(true);
try {
return client.restHighLevelClient.update(request, RequestOptions.DEFAULT);
} catch (IOException e) {
log.error(e.getMessage());
}
return null;`

now ,this datetime format is corret in kibana, but is incorret in dejavu like 'yyyy-08-Sa 07:54:58.366'
`{
"_index": "test_info",
"_type": "_doc",
"_id": "22321",
