在Spring Boot中将忽略Elasticsearch的@Setting注释 [英] @Setting annotation for Elasticsearch is ignored in Spring Boot

问题描述

在我的Spring Boot应用程序中，我有一个@Setting注释指向设置JSON文件，但似乎被完全忽略了。

In my Spring Boot application I have a @Setting annotation pointing to a settings JSON file but it seems to be completely ignored.

@Setting(settingPath = "/settings/elasticsearch-settings.json")
@Document(indexName = "hermes", type = "client", shards = 1, replicas = 0, refreshInterval = "-1")
public class Client {

    @Id
    private String externalId;
    private String name;
    private String surname;
    private String taxNumber;
    private String uid;

    //getters and setter intentionally left out
}

我的设置文件位于：

src/main/resources/settings/elasticsearch-settings.json

文件内容如下：

{
  "analysis": {
    "analyzer": {
      "my_ngram_analyzer": {
        "tokenizer": "my_ngram_tokenizer"
      }
    },
    "tokenizer": {
      "my_ngram_tokenizer": {
        "type": "nGram",
        "min_gram": "2",
        "max_gram": "3",
        "token_chars": [
          "letter",
          "digit"
        ]
      }
    }
  }
}

当我使用Elasticsearch REST API运行此命令时，它会更改设置没问题，所以我认为JSON本身是有效的。但是，即使我放置了无效的JSON或一起删除了文件，我也一无所获，Spring也没有警告或错误。这就是为什么我的猜测是完全忽略了注释。

When I run this using Elasticsearch REST api it changes the settings without a problem, so I guess the JSON itself is valid. But even when i put an invalid JSON, or delete the file all together, I get nothing, no warning or error from Spring. That is why my guess is that the annotation is completely ignored.

如果可能与此相关，那么我还有一个Elasticsearch配置类，我可以使用它来公开客户端在端口9200上进行注释。

If it might have anything to do with this, I also have an Elasticsearch configuration class that I use to expose the client on port 9200. It is annotated with:

@EnableConfigurationProperties(ElasticsearchProperties.class)

然后：

@EnableAutoConfiguration(exclude= { ElasticsearchAutoConfiguration.class })

我的主类的注释。

推荐答案

您的 elasticsearch-settings.json 文件缺少索引元素。改为这样尝试：

Your elasticsearch-settings.json file is missing the index element. Try like this instead:

{
  "index": {
    "analysis": {
      "analyzer": {
        "my_ngram_analyzer": {
          "tokenizer": "my_ngram_tokenizer"
        }
      },
      "tokenizer": {
        "my_ngram_tokenizer": {
          "type": "nGram",
          "min_gram": "2",
          "max_gram": "3",
          "token_chars": [
            "letter",
            "digit"
          ]
        }
      }
    }
  }
}
