1. 引入依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
2. application.yml增加配置
upload:url: http://localhost:8080/api/upload
3. 生成RestTemplate
@Configuration
public class BeanConfig {@Beanpublic RestTemplate restTemplate(){return new RestTemplate();}
}
4. 上传服务
@Slf4j
@Service
public class FileUploadService implements IFileUploadService {@Resourceprivate RestTemplate restTemplate;@Value("${upload.url}")private String uploadUrl;@Overridepublic boolean uploadExcel(File file, String taskId, String sign) {HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.MULTIPART_FORM_DATA);FileSystemResource resource = new FileSystemResource(file);MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();body.add("file", resource);body.add("taskId", taskId);body.add("sign", sign);HttpEntity<MultiValueMap<String, Object>> request = new HttpEntity<>(body, headers);ResponseEntity<Boolean> response = restTemplate.postForEntity(uploadUrl, request, Boolean.class);if (!response.getStatusCode().equals(HttpStatus.OK)) {return false;}return response.getBody();}
}
