resttemplate配置支持http和https

RestTemplate 是 Spring Framework 提供的一个用于访问 RESTful Web 服务的模板类，支持 HTTP 和 HTTPS 协议。下面是 RestTemplate 配置支持 HTTP 和 HTTPS 的步骤：

1. 引入 RestTemplate 相关依赖：

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web-services</artifactId>
   </dependency>

2. 配置 RestTemplate：

   @Configuration
   public class RestTemplateConfig {
   
       @Bean
       public RestTemplate restTemplate(RestTemplateBuilder builder) {
           return builder.build();
       }
   }

3. 进行 HTTP 请求：

   @Autowired
   private RestTemplate restTemplate;
   
   public void sendHttpRequest() {
       String url = "http://example.com/api/users";
       ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
       String responseBody = response.getBody();
       // ...
   }

4. 进行 HTTPS 请求：

   @Autowired
   private RestTemplate restTemplate;
   
   public void sendHttpsRequest() throws Exception {
       String url = "https://example.com/api/users";
       SSLContext sslContext = SSLContextBuilder.create()
               .loadTrustMaterial(null, (certificate, authType) -> true)
               .build();
       SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext);
       HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
       HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
       restTemplate.setRequestFactory(factory);
       ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
       String responseBody = response.getBody();
       // ...
   }

以上是 RestTemplate 配置支持 HTTP 和 HTTPS 的步骤，具体实现可根据实际需要进行调整。
