tomcat 页面图片管理服务器配置

1、在tomcat的server.xml配置文件中设置docBase：需要写在Value标签下面，如下：

<Context docBase="/opt/traceupload/upload" path="/upload"></Context>

1、需要在服务器上手动创建文件夹base路径：opt/traceupload/upload文件夹。
2、在server.xml中配置URIEncoding="UTF-8"，解决<img>标签的src属性不兼容中文的图片名称，配置如下：
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>
