报错:

16-Jan-2021 16:30:38.436 信息 [http-apr-8080-exec-8] org.apache.tomcat.util.http.Parameters.processParameters More than the maximum number of request parameters (GET plus POST) for a single request ([10,000]) were detected. Any parameters beyond this limit have been ignored. To change this limit, set the maxParameterCount attribute on the Connector.
 Note: further occurrences of this error will be logged at DEBUG level.

以上问题是因为tomcat 默认配置数据接受容量是1万,如需要提交1万条以上数据需要配置tomcat的maxParameterCount,

maxParameterCount在tomcat是默认配置,是1万条数据。在Connector 中,配置maxParameterCount来进行限制提交数据量,-1为无限。

例如:

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" 
               maxPostSize="-1" 
               maxParameterCount="-1"/>

将maxPostSize和maxParameterCount设为-1,则不受限制

以上就是关于大数据量提交,后台无法接受数据的问题。
