我在 Wildfly 10.0.0.Final 上上传大于 10MB 的文件时遇到问题。这里有我的standalone.xml 文件
<subsystem xmlns="urn:jboss:domain:undertow:3.0">
<buffer-cache name="default" />
<server name="default-server">
<http-listener name="default" socket-binding="http"
redirect-socket="https" max-post-size="31457280"/>

<host name="default-host" alias="localhost">
<location name="/" handler="welcome-content" />
<!-- <filter-ref name="server-header" /> -->
<!-- <filter-ref name="x-powered-by-header" /> -->
</host>
</server>
<servlet-container name="default">

</servlet-container>
<handlers>

<response-header name="x-powered-by-header"

</filters>
</subsystem>
这是我尝试上传大于 10MB 的文件时遇到的异常：

尽管配置文件中将限制设置为 30MB，但为什么 Wildfly 会抱怨 10MB 限制？
解决了。 这是 Spring 配置的问题，而不是 Wildfly 的配置问题。我把这个答案留在这里，以防它对我们的后代有帮助......:-)
