<号码：文件上传>限制到2 Mb [英] <p:fileUpload> limiting to 2 Mb

问题描述

我遇到了 fileUpload 的问题。当文件大于2 MB时，它不会触发 fileUploadListener 。组件：

 < p：fileUpload id =uploadrequired =true
 fileUploadListener =＃{myBean.handleFileUpload}
 fileLimit =1
 requiredMessage =需要文件
 fileLimitMessage =仅一个文件
 invalidFileMessage =无效文件
 cancelLabel =取消label = 选择
 allowTypes =/（\。| \ /）（gif | jpe？g | png）$ //> 
  

环境：JSF 2.2.3，Primefaces 4.0，Tomcat 7

可能是一些过滤器配置问题？

@EDIT：更多信息。与 mode =simple。

解决方案

默认最大POST大小为2MB，可在 HTTP < Connector> 配置在 /conf/server.xml 中。以下是文档的摘录：

maxPostSize

最大字节数的POST将由容器FORM URL参数解析处理。如果未指定此属性，则将此属性设置为2097152（2兆字节）。

可以通过将此属性设置为小于或等于0的值来禁用限制。

因此，如果您想禁用它，请这样做：

 < Connector ... maxPostSize =  -  1 > 
  

（ 0 但 -1 更自我记录为允许每个尺寸）

I'm having some issues with fileUpload. It's not firing the fileUploadListener when the file is > 2 Mb.

The component:

<p:fileUpload id="upload" required="true"
fileUploadListener="#{myBean.handleFileUpload}"
fileLimit="1"
requiredMessage="A file is required"
fileLimitMessage="One file only"
invalidFileMessage="Invalid file"
cancelLabel="Cancel" label="Choose"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

Enviroment: JSF 2.2.3, Primefaces 4.0, Tomcat 7

Might it be some "filter" configuration problem?

@EDIT: More info. Same problem with mode="simple".

解决方案

Tomcat has a default maximum POST size of 2MB which is configurable in the HTTP <Connector> configuration in its /conf/server.xml. Here's an extract from the documentation:

maxPostSize

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Thus, if you want to disable it, do so:

<Connector ... maxPostSize="-1">

(0 can also, but the -1 is more self-documenting as to "allow every size")
