Spring数据Elasticsearch。因为冲突而无法合并。无法更新[_source]的启用设置]。

Question

我想禁用 _source 场与 春天数据Elasticsearch为了添加这个属性。

"_source": {
    "enabled": false
}

我正在做以下工作 @Configuration 类。

    @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;
    }

但我得到了以下异常。

错误发生的原因是，在这个配置下，我试图设置了... enabled 的变量 org.elasticsearch.index.mapper.internal.SourceFieldMapper 到 假的但由于一些奇怪的原因，它被一个已经设置了该属性的实例检查为 真正.

我怎么能做配置该字段为假？

谢谢。

这个错误只发生在你试图更新一个对象的映射时。现有 索引。在你的情况下，已经有'电脑'指数与 _source 设为 真正. 你可以通过运行

GET /computer/_mapping

这将返回

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

的映射值 _source 归档 不能 被更新。

如果您需要更改映射，请使用正确的映射创建一个新的索引，并将您的数据重新编入该索引。

或者，您可以使用以下方法删除计算机索引

DELETE /computer

而Spring Data将在启动时创建具有正确映射的索引。
