问题分析出现问题的时候，尝试了拷贝服务器到另一个服务器，对另一个服务器进行了修改。
1、修改了另一个服务器的port，改为8090，打开tomcat\confi\server.xml，修改
<Connector port="8090" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
2、打开tomcat\confi\web.xml，添加加粗加斜的部分，因为tomcat默认只读，要实现上传到另一台服务器，需要设置它为可写。
default
org.apache.catalina.servlets.DefaultServlet
debug
0
readonly
false
listings
false
1
3、通过设置以上两项，按理说应该就能实现了，结果一直报错，怎么想都是自己太笨太懒，没有耐心向下看错误描述。
问题解决org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:200) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)
之后一直尝试，突然发现将文件名中文部分删掉，上传就成功了。
好气啊，花了好多时间，但错误已经写在错误描述里了，就当买个教训了，以后要多读错误描述。
