你们好，我是金金金。

场景

我正在使用Springboot整合elasticsearch，在创建索引(分词器) 运行报错，如下

排查

排查之前我先贴一下代码

java 复制代码

import org.elasticsearch.action.admin.indices.create.CreateIndexRequest; // 注意这个包


@SpringBootTest
public class RestHighLevelClientTest {
  // 当前客户端是手工维护的，因此不能通过自动装配的形式加载对象
  private RestHighLevelClient client;
  
  @BeforeEach
  void setUp() {
    HttpHost host = HttpHost.create("http://localhost:9200"); // 配置ES服务器地址与端口9200
    RestClientBuilder builder = RestClient.builder(host);
    client = new RestHighLevelClient(builder);
  }
  
  @AfterEach
  void tearDown() throws IOException {
    client.close();
  }
  
  @Test
  void testCreateIndexByIK() throws IOException {
    CreateIndexRequest request = new CreateIndexRequest("books");
    String json = "{\n" +
      "    \"mappings\": {\n" +
      "        \"properties\": {\n" +
      "            \"id\": {\n" +
      "                \"type\": \"keyword\"\n" +
      "            },\n" +
      "            \"name\": {\n" +
      "                \"type\": \"text\",\n" +
      "                \"analyzer\": \"ik_max_word\",\n" +
      "                \"copy_to\": \"all\"\n" +
      "            },\n" +
      "            \"type\": {\n" +
      "                \"type\": \"keyword\"\n" +
      "            },\n" +
      "            \"description\": {\n" +
      "                \"type\": \"text\",\n" +
      "                \"analyzer\": \"ik_max_word\",\n" +
      "                \"copy_to\": \"all\"\n" +
      "            },\n" +
     "            \"all\": {\n" +
      "                \"type\": \"text\",\n" +
      "                \"analyzer\": \"ik_max_word\"\n" +
      "            }\n" +
      "        }\n" +
      "    }\n" +
      "}";

    //设置请求中的参数
    request.source(json, XContentType.JSON);
    client.indices().create(request, RequestOptions.DEFAULT);
  }
}
