播放Framework文件上传空参数

Question

Im working on a Play Framework 1.4 application using Apache2.4 as my webserver.

I am trying to do a basic file upload however if I try to upload a file that is larger than 487KB the params are empty, if i upload a file thats less than 487KB the params are there and I can acccess the file from the tmp path. Here is the code:

// File <= 487KB Logs "params: {file=[Ljava.lang.String;@160b7aab}"
// File > 487KB Logs "params: {}"
public static String uploadFile() {
    Logger.info("params: %s", params.all());
    return "";
}

I have my apache config setup to allow large size payloads and headers:

LimitRequestFields 0
LimitRequestBody 0
LimitRequestFieldSize 2097152

Any advice on this would be great.

Okay so it turns out this was a Play Framework configuration limit. Quite hard to find nested within their documentation. You need to set the Max Content Length to whatever size files you want to upload (in bytes):

play.netty.maxContentLength = 2097152

Alternately if you dont want a max size you can set it to -1 .

play.netty.maxContentLength = -1
