我正在尝试发现一种记录返回PDF(或任何其他文件)的API的方法。
使用Spring,我的Rest资源是这样的:
@Override
@GetMapping(produces = "application/pdf")
public ResponseEntity<InputStreamResource> find(
@PathVariable long id
) {
Result result = service.find(id);
HttpHeaders headers = disableCache();
return ResponseEntity
.ok()
.headers(headers)
.contentLength(result.getSize())
.contentType(MediaType.parseMediaType("application/pdf"))
.body(new InputStreamResource(result.getFileInputStream()));
}
这适用于下载文件。但我不知道使用Swagger记录响应的良好做法。
实际上,我尝试使用Swagger注释:
@ApiOperation(value = "Some description")
@ApiResponses(value = {
@ApiResponse(code = 200, message = "Success.")
})
@ResponseStatus(HttpStatus.OK)
@GetMapping(produces = "application/pdf")
ResponseEntity<InputStreamResource> find(
@PathVariable long id
);
但Swagger在Swagger-ui上返回InputStreamResource
作为Json的内容,不结果。
如何代表Swagger响应的文件下载?

让我们尝试像这样更新代码:
headers.add("Content-Type", "application/pdf");
headers.add("Content-Disposition", "attachment; filename=report.pdf");

注释被忽略,但这对我有用:
TypeResolver typeResolver = new TypeResolver();
new Docket(DocumentationType.OAS_30)
.alternateTypeRules(AlternateTypeRules.newRule(
typeResolver.resolve(ResponseEntity.class, InputStreamResource.class),
typeResolver.resolve(Byte.class),
DIRECT_SUBSTITUTION_RULE_ORDER));
