如何从客户端Java调用PUT方法？

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPut;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class HttpClientExample {
    public static void main(String[] args) {
        HttpClient httpClient = HttpClientBuilder.create().build();
        String url = "http://example.com/api/resource";
        
        try {
            HttpPut httpPut = new HttpPut(url);
            
            // 设置请求体
            String requestBody = "This is the request body";
            StringEntity entity = new StringEntity(requestBody);
            httpPut.setEntity(entity);
            
            // 设置请求头
            httpPut.setHeader("Content-Type", "application/json");
            
            // 发送请求
            HttpResponse response = httpClient.execute(httpPut);
            
            // 获取响应
            HttpEntity responseEntity = response.getEntity();
            String responseBody = EntityUtils.toString(responseEntity);
            
            // 处理响应
            System.out.println("Response status code: " + response.getStatusLine().getStatusCode());
            System.out.println("Response body: " + responseBody);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
