Spring 数据 Elasticsearch : Can't merge because of conflicts: [Cannot update enabled setting for [_source]]

Question

我正在尝试禁用 _source字段与 Spring Data Elasticsearch ，为了添加这个属性:

"_source": {
    "enabled": false
}

我在 @Configuration 中执行以下操作类(class):

    @Bean
    public ElasticsearchTemplate elasticsearchTemplate() throws IOException {
        ElasticsearchTemplate template = new ElasticsearchTemplate(getNodeClient());
        Map<Object, Object> mapping = new LinkedHashMap<Object, Object>();
        if (template.indexExists(Computer.class)){
            mapping = template.getMapping(Computer.class);                  
        } else {
            template.createIndex(Computer.class);
        }
        LinkedHashMap<String, Boolean> hashMap = new LinkedHashMap<String, Boolean>();
        hashMap.put("enabled", false);
        mapping.put("_source", hashMap);
        template.putMapping(Computer.class, mapping);
        return template;
    }

但我得到以下异常:

发生错误是因为使用该配置我试图设置 enabled org.elasticsearch.index.mapper.internal.SourceFieldMapper 的变量至 假 ，但出于某种奇怪的原因，它正在
使用已将该属性设置为 的实例进行检查真 .

我该怎么做才能将该字段配置为 false？

谢谢。

此错误仅在您尝试更新 的映射时发生。现有 指数。在您的情况下，已经有 _source 的“计算机”索引设置为 真 .您可以通过运行来检查

GET /computer/_mapping

这将返回

{
  "computer": {
    "mappings": {
      "_source": {
        "enabled": true
      }
    }
  }
} 

_source的映射值已提交 不能 被更新。

如果需要更改映射，请使用正确的映射创建新索引并将数据重新索引到该索引中。

或者，您可以删除计算机索引

DELETE /computer

Spring Data 将在启动时创建具有正确映射的索引。
