springboot发起https请求

Spring Boot可以使用Java的HttpURLConnection或Apache HttpClient库来发起HTTPS请求。以下是使用Apache HttpClient库的示例代码：

1. 添加Apache HttpClient库依赖

在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.12</version>
</dependency>

2. 创建HttpClient对象

CloseableHttpClient httpClient = HttpClients.createDefault();

3. 创建HttpGet或HttpPost对象

HttpGet httpGet = new HttpGet("https://example.com");
HttpPost httpPost = new HttpPost("https://example.com");

4. 设置请求头和请求体（如果有）

httpPost.setHeader("Content-Type", "application/json");
StringEntity entity = new StringEntity("{\"key\":\"value\"}", ContentType.APPLICATION_JSON);
httpPost.setEntity(entity);

5. 发起请求并获取响应

CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity responseEntity = response.getEntity();
String responseString = EntityUtils.toString(responseEntity);

6. 关闭HttpClient和HttpResponse对象

response.close();
httpClient.close();

以上是使用Apache HttpClient库发起HTTPS请求的基本流程，具体实现可以根据需求进行调整。
