When using jetty to run items, an error is reported: form too large or form too many keys

use Jetty As a server Web Project time ,Form If the submitted data is too large, the following two errors will be reported ：

• java.lang.IllegalStateException: Form too large 205685>200000  

• java.lang.IllegalStateException: Form too many keys

  Under the baidu , The two anomalies found are jetty Throw the jetty Limit Form The size of the submitted data , The source class comes from jetty lib Under the Treasury jetty-server-7.6.16.v20140903.jar Under bag org.eclipse.jetty.server.Request class .

  jetty Limit form The largest number of submitted data size And the biggest keys Count , You can see in the code ,jetty Default maxFormContentSize by 200000,maxFormKeys by 1000; And if the data we submit exceeds these two values , It's the two above Java abnormal .

Jetty There are two ways to solve this problem , Choose one of them ：

1. modify Jetty Of jetty.xml file ,jetty.xml The file in jetty In the root directory etc Catalog , stay jetty.xml Add the following configuration... To the file ：

<Call name="setAttribute">	<Arg>org.eclipse.jetty.server.Request.maxFormContentSize</Arg>	<Arg>-1</Arg></Call>	<Call name="setAttribute">	<Arg>org.eclipse.jetty.server.Request.maxFormKeys</Arg>	<Arg>-1</Arg></Call>

maxFormContentSize The default is 200000,maxFormKeys yes 1000, We just need to change these two values to the maximum value we need , Another value is to set both values to less than 0 Any value , It's usually -1, Means unrestricted Form The size of the submitted data .

2. stay web In the project WEB-INF Create a new folder jetty-web.xml file , stay jetty-web.xml Add the following to the file ：

<?xml version="1.0”encoding="UTF-8"?><!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN""http://jetty.mortbay.org/configure.dtd"><Configure id="WebAppContext" class="org.eclipse.jetty.webapp.WebAppContext">	<Set name="maxFormContentSize">200000</Set>	<Set name="maxFormKeys">1000</Set></Configure>|

take maxFormContentSize and maxFormKeys Change the value of to the value you want .

3.Spring Boot Project configuration :

• properties Configuration mode

  #POST Form length limit （5MB）server.jetty.max-http-post-size=5000000
