jetty9请求form表单太大

jetty默认的表单最大size为200000，

参考：http://www.eclipse.org/jetty/documentation/current/setting-form-size.html

For All Apps on a Server

Set an attribute on the Server instance for which you want to modify the maximum form content size:

<Configure class="org.eclipse.jetty.server.Server">
<Call name="setAttribute">
<Arg>org.eclipse.jetty.server.Request.maxFormContentSize</Arg>
<Arg>200000</Arg>
</Call>
</Configure>

-------------------------------------------------------------------------------------------------------

解决方法：

修改/opt/jetty9/etc/jetty.xml配置文件，在Configure中添加如下

<Call name="setAttribute">
<Arg>org.eclipse.jetty.server.Request.maxFormContentSize</Arg>
<Arg>500000</Arg>
</Call>
