JBoss 获取最大帖子大小

Question

While I have managed to increase the max post size on my JBoss following http://www.mastertheboss.com/web/jboss-web-server/configuring-wildfly-upload-file-size/ now I'd like my webapp to inform users. So I would like to render on the screen that the server accepts upload up to XXX MB.

How can a webapp retrieve the max post size setting from JBoss? Is there even a container agnostic way that could work across different servlet containers?

Answer 1

The max-post-size allows for an expression . That means you could use a system property which could be set on the attribute and retrieved by your application.

In CLI you'd do something like this:

/system-property=max.post.size:add(value=25485760)
/subsystem=undertow/server=default-server/http-listener=default/:write-attribute(name=max-post-size,value=${max.post.size:10485760})

While the default, :10485760 , is not strictly required, I'd advise it.

Then in your application you simply just to simply retrieve the system property.
