Nginx 代理 Tomcat 问题 request.getRequestURI(); 怎么让他不带项目名

Question

如果nginx下面这样的配置
我访问http://kaipizhe.com这个时候request.getRequestURI();这个值是/kaipizhe/而不是/
我访问http://kaipizhe.com/all/这个时候request.getRequestURI();这个值是/kaipizhe/all/而不是/all/
就是request.getRequestURI();都会带上/kaipizhe/，怎么让他直接是/，
是不是我nginx配置有问题，应该怎么处理
nginxlog_formatkaipizhe.com'$remote_addr-$remote_user[$time_local]"$request"'
'$status$body_bytes_sent"$http_referer"'
'"$http_user_agent"$http_x_forwarded_for';
