这是我的server.xml文件的配置
<Connector executor="tomcatThreadPool" port="8443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
scheme="https" secure="true" connectionTimeout="40000" connectionUploadTimeout="36000000" disableUploadTimeout="false" bufferSize="4096" acceptCount="250" clientAuth="false" sslProtocol="TLS"
/>
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" secure="true" executor="tomcatThreadPool"
enableLookups="false" acceptCount="250" connectionTimeout="40000" packetSize="21000" redirectPort="8443" bufferSize="4096" />
我的web.xml上传参数是： -
<context-param>
<!-- max size of the upload request -->
<param-name>maxSize</param-name>
<param-value>26214400</param-value>
</context-param>
答案 0 :(得分：0)
您还需要将此添加到您的web.xml。大小是八位字节
<context-param>
<param-name>maxSize</param-name>
<param-value>100000</param-value>
</context-param>
