spring中如何发送带有查询参数"test[]=test“的请求？

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;

import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;

public class ExampleRequest {
    public static void main(String[] args) throws UnsupportedEncodingException {
        RestTemplate restTemplate = new RestTemplate();
        
        // URL编码查询参数
        String encodedQuery = URLEncoder.encode("test[]", StandardCharsets.UTF_8.toString()) + "=test";
        
        // 构建请求头
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        
        // 发送请求
        HttpEntity<String> entity = new HttpEntity<>(headers);
        ResponseEntity<String> response = restTemplate.exchange("http://example.com/api?"+encodedQuery, HttpMethod.GET, entity, String.class);
        
        // 处理响应
        if (response.getStatusCode().is2xxSuccessful()) {
            System.out.println("请求成功：" + response.getBody());
        } else {
            System.out.println("请求失败：" + response.getStatusCode());
        }
    }
}
