我正在尝试使用多部分/表单数据作为内容类型上载一个既有文本字段又有图像的表单。当我在我的角度应用程序中完成post时,我可以在控制台中清楚地看到内容类型是正确的,请求有效负载由两个不同的部分组成,分别名为seedImage和seedDetails。以下是两个屏幕截图,说明了这一点:
请求头:
请求负载:
然而,当请求arrivÃs出现在我的spring boot应用程序时,它抛出了这个异常。

这是我的控制器:
private Status createSeed(@RequestPart("seedImage") MultipartFile seedImage, @RequestPart("seedDetails") CreateSeedDTO createSeedDTO){
logger.info(createSeedDTO.toString());
User author = userDao.findByUserName(createSeedDTO.getAuthor()).orElseGet(null);
if(author == null)
return new Status(false,"User " + createSeedDTO.getAuthor() + " is unknown to the database.");
else {
SeedRecord seedRecord = new SeedRecord(createSeedDTO);
seedRecord.setAuthor(author);
return seedCalendarService.createNewSeedRecord(seedRecord);
}
}
我已经试过用@RequestParam更改@RequestPart,但是没有效果。
我试图让这项工作的例子,克雷格墙他的书春季行动第四版。在他的书中,他说你需要做一些这样的配置:
Webappinitializer配置:
public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{
@Override
protected void customizeRegistration(ServletRegistration.Dynamic registration){
registration.setMultipartConfig(new MultipartConfigElement("/tmp/images/uploads", 3145728, 4194304, 0));
}
}
在Java配置类中,您将:
@Bean
public MultipartResolver multipartResolver() throws IOException{
return new StandardServletMultipartResolver();
}
有人能告诉我我做错了什么吗?我认为问题不在于来自角度应用程序的请求,因为请求中的所有内容看起来都很好。
