tomcat隐藏400报错信息

解决tomcat 安全漏洞，http 400报错，开发人员在tomcat新增了错误页面，页面未跳转，没解决

我在nginx配置文件中新增了配置解决了；

upstream web_tomcat {ip_hash;server 192.168.1.62:8082 weight=1;server 192.168.1.63:8082 weight=1;server 192.168.1.64:8082 weight=1;server 192.168.1.65:8082 weight=1;server 192.168.1.66:8082 weight=1;server 192.168.1.67:8082 weight=1;server 192.168.1.68:8082 weight=1;server 192.168.1:8082 weight=1;keepalive 768;
}server {listen 80;server_name your-domain.com;location / {proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header REMOTE-HOST $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://web_tomcat/demo/;# 关键：捕获来自后端的 400 错误，并重定向到指定 URLproxy_intercept_errors on;error_page 400 =302 https://your-domain.com/error-page.html;}
}
