1. 添加依赖
代码语言：javascript
复制<!-- https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp -->
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.3.1</version>
</dependency>
2. 声明 RestTemplate
代码语言：javascript
复制@Component
public class WebConfig {
/**
* 基于OkHttp3配置RestTemplate
* @return
*/
@Bean
public RestTemplate restTemplate() {
return new RestTemplate(new OkHttp3ClientHttpRequestFactory());
}
}
3. 测试controller
代码语言：javascript
复制@RestController
public class RestTemplateController {
@Autowired
private RestTemplate restTemplate;
@GetMapping("/testRestTemplate")
public GraceJSONResult testRestTemplate(Model model) {
ResponseEntity<IMOOCJSONResult> responseEntity =
restTemplate.getForEntity("http://localhost:8001/article/queryIndexArticleList?page=0&pageSize=10", IMOOCJSONResult.class);
Map result = (Map)responseEntity.getBody().getData();
return GraceJSONResult.ok(result);
}
}
