本文详细介绍了如何在Spring Boot项目中配置RestTemplate，包括添加依赖、注入Bean以及使用RestTemplate上传文件的具体实现过程。

添加依赖：

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

注入Bean

import org.springframework.context.annotation.Bean;  
import org.springframework.context.annotation.Configuration;  
import org.springframework.http.client.ClientHttpRequestFactory;  
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;  
import org.springframework.web.client.RestTemplate;  
 
@Configuration  
public class RestTemplateConfig {  
 
   @Bean  
   public RestTemplate restTemplate(ClientHttpRequestFactory factory) {  
       return new RestTemplate(factory);  
   }  
 
   @Bean  
   public ClientHttpRequestFactory clientHttpRequestFactory() {  
       HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();  
       httpRequestFactory.setConnectionRequestTimeout(30000);  
       httpRequestFactory.setConnectTimeout(30000);  
       httpRequestFactory.setReadTimeout(30000);  
       return httpRequestFactory;  
   }  
 
}

上传文件

@Autowired  
private RestTemplate restTemplate;  
  
public void upload(){  
    File file = new File("xx");  
    FileSystemResource resource = new FileSystemResource(file);  
    MultiValueMap<String, Object> param = new LinkedMultiValueMap<>();  
    param.add("file", resource);  
    String result = restTemplate.postForObject("xx", param, String.class);  
}
