作为分段文件上传时是否有最大文件大小

问题描述

  HttpPost post = new HttpPost(properties.getPropert("system.api.url"));
            post.setHeader("Accept", "application/json");
            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);
            entity.addPart("file", new FileBody(file, event.getMIMEType()));
            post.setEntity(entity);

这是我将文件作为Multipart文件上传到我的rest控制器的方式.有没有可以上传的最大文件大小，或者有什么方法可以定义此类上传的最大文件大小.我在Vaadin客户端使用此代码.

This is how I upload the file as a Multipart file to my rest controller. Is there a max file size that can be uploaded or is there any way that I can define a max file size foe this kind of uploading. I use this code in my Vaadin client side.

推荐答案

在您的配置中尝试以下操作:

Try this in your config:

@Bean
public MultipartResolver multipartResolver() {
    return new StandardServletMultipartResolver();
}

@Bean
MultipartConfigElement multipartConfigElement() {
    MultiPartConfigFactory factory = new MultiPartConfigFactory();
    factory.setMaxFileSize(env.getRequiredProperty("MAX.FILE.SIZE"));
    factory.setMaxRequestSize(env.getRequiredProperty("MAX.FILES.SIZE"));
    factory.setFileSizeThreshold(env.getRequiredProperty("MAX.MEMORY.SIZE"));
    factory.setLocation(env.getRequiredProperty("IMAGE.PROCESSOR.UPLOADTMP"));

    return factory.createMultipartConfig();
}

我假设env是Spring配置环境变量.或者只是放值.

I assume that env is Spring configuration environment variables.Or just put values instead.
