写一个springboot 调用kibana api 在kibana中创建用户和角色的demo

以下是一个使用Spring Boot调用Kibana REST API创建用户和角色的示例： 1. 添加依赖 在pom.xml文件中添加以下依赖： ```xml org.springframework.boot spring-boot-starter-web org.apache.httpcomponents httpclient 4.5.13 com.fasterxml.jackson.core jackson-databind 2.12.5 ``` 2. 创建KibanaService类 创建一个名为KibanaService的类，该类包含用于调用Kibana REST API的方法。以下是一个示例： ```java import com.fasterxml.jackson.databind.ObjectMapper; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.ContentType; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Service; import java.io.IOException; import java.util.HashMap; import java.util.Map; @Service public class KibanaService { @Value("${kibana.url}") private String kibanaUrl; @Value("${kibana.username}") private String kibanaUsername; @Value("${kibana.password}") private String kibanaPassword; private final ObjectMapper objectMapper = new ObjectMapper(); public void createUser(String username, String password) throws IOException { Map requestBody = new HashMap<>(); requestBody.put("password", password); requestBody.put("full_name", username); String jsonBody = objectMapper.writeValueAsString(requestBody); HttpPost request = new HttpPost(kibanaUrl + "/api/security/v1/users"); request.setHeader("Content-Type", "application/json"); request.setHeader("kbn-xsrf", "true"); request.setHeader("Authorization", "Basic " + getAuthHeader()); StringEntity entity = new StringEntity(jsonBody, ContentType.APPLICATION_JSON);
