如何在java中使用HttpClient将api生成的jwt token获取到我的应用程序中？

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

public class JWTTokenFetcher {
    public static void main(String[] args) {
        try {
            // 创建HttpClient实例
            HttpClient httpClient = HttpClientBuilder.create().build();

            // 创建HttpPost请求
            HttpPost httpPost = new HttpPost("API的URL");

            // 设置请求头
            httpPost.setHeader("Content-Type", "application/json");
            httpPost.setHeader("Authorization", "Bearer " + "API生成的JWT Token");

            // 发送请求并获取响应
            HttpResponse response = httpClient.execute(httpPost);

            // 解析响应
            HttpEntity entity = response.getEntity();
            String responseString = EntityUtils.toString(entity, "UTF-8");

            // 处理响应，解析出JWT Token
            // ...

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
