这是我的服务器.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"                                                                    />

我的网络.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>

您还需要将其添加到您的网络.xml。大小以八位字节为单位

    <context-param>
        <param-name>maxSize</param-name>
        <param-value>100000</param-value>
    </context-param>
