Question

我在我的应用程序中使用springboot + jersey。我正在使用嵌入式tomcat。以下是API的定义。

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response createNewBadge(@FormDataParam("name") String name,
                               @DefaultValue("0") @FormDataParam("grade") int grade,
                               @DefaultValue("0") @FormDataParam("point") int point,
                               @FormDataParam("file") InputStream fileInputStream,
                               @FormDataParam("file") FormDataContentDisposition disposition) {
    ...
}

当我启动应用程序并访问此API提供的路径时，我将得到以下错误。我在这里错过了什么吗？

Answer 1

使用Spring启动时，支持2.15版本的运动衫。请更改多部分球衣依赖的版本。

Answer 2

经过一番搜索，我找出了根本原因。我需要在球衣配置上注册MultiPartFeature类，如下所示：

@Configuration
public class JerseyConfiguration extends ResourceConfig {
  public JerseyConfiguration(){
    register(MultiPartFeature.class);
  }
}

使用springboot时，Multipart API在Jersey中不起作用
