http://localhost:9200/_analyze { "analyzer":"ik_max_word", "text":"文档数据库" } 转成java代码查询

你可以使用Java的HTTP请求库来发送HTTP请求并获取响应。以下是一个示例代码，用于将给定的文本通过HTTP请求发送到Elasticsearch的`_analyze`端点，并使用`ik_max_word`分词器进行分析：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class ElasticsearchAnalyzer {
    public static void main(String[] args) {
        try {
            // Elasticsearch _analyze endpoint URL
            String url = "http://localhost:9200/_analyze";

            // Text to be analyzed
            String text = "文档数据库";

            // Set the analyzer and text parameters
            String params = String.format("analyzer=%s&text=%s",
                    URLEncoder.encode("ik_max_word", "UTF-8"),
                    URLEncoder.encode(text, "UTF-8"));

            // Create the HTTP connection
            HttpURLConnection connection = (HttpURLConnection) new URL(url + "?" + params).openConnection();
            connection.setRequestMethod("GET");

            // Get the response
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // Print the response
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

请确保你已经在本地启动了Elasticsearch，并将URL中的`localhost:9200`替换为你的Elasticsearch实例的地址。以上代码将发送GET请求到`http://localhost:9200/_analyze?analyzer=ik_max_word&text=文档数据库`，并打印出分析结果。
