Test

Via Tomcat, demandez l'URL : http://test.nt.springmvc.com :...
Via Nginx, demandez l'URL : http://test.nt.springmvc.com/
Via Nginx, demandez l'URL : http://test.nt.springmvc.com/...
Via Nginx, demandez l'URL : http://test.nt.springmvc.com/...

Comme vous pouvez le voir dans les journaux, ma quatrième demande n'a pas été transmise à Tomcat. J'ai recherché de nombreux documents sur Internet et je n'ai pas trouvé où le problème s'est produit. Vous trouverez ci-dessous la page Web correspondante

Solution

Configuration Nginx (/nginx/sites-available/default)

upstream tomcat {   
 server 192.168.182.129:8080;   
} 

server {
    listen 80 default_server;
    listen [::]:80 ;

    root /opt/apache-tomcat-8.5.4/webapps/springmvc;

    server_name test.nt.springmvc.com;

    location / {
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://tomcat;
        #try_files $uri $uri/ =404;
    }
}

Vous pouvez voir cela dans le fichier de configuration nginx, commentez try_files $uri $uri/ =404 et vous pouvez y accéder normalement

try_files

try_files sur nginx détermine si le fichier existe

$uri

Fait référence au fichier et au chemin demandés, à l'exclusion des éléments après "?" ou "#"
$request_uri : /stat.php?id=1585378&web_id=1585378
$uri /stat.php
$document_uri : /stat php

upstream tomcat { server 192.168.182.129:8080; } server { listen 80 default_server; listen [::]:80 ; root /opt/apache-tomcat-8.5.4/webapps/springmvc; #**(这行拿掉)** #server_name _; server_name test.nt.springmvc.com; location /{ # location / { 斜杠后面加空格 proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://tomcat; try_files $uri $uri/ =404; } }
