位置：router文件夹下面的index.js

const router = new Router({
  base: '/nhtjfx/', // 路由前缀（该地方配置后，会发现你的启动地址也会加上这个前缀）
  mode: 'history', // 采用history模式URL的路径才跟配置的对应上，不然URL是先加/#再追加配置的地
  routes:[...]
  });
（2）实现静态文件加前缀
 位置：vue.config.js
 
静态资源css,js之类的的src或href引用位置会加上这个前缀,会体现在打包后的index.html文件内容
 例如
 
 未加之前：<link href="./static/js/chunk-c8ec8b4a.e230ecc5.js" rel="prefetch">
  加之后：<link href="/nhtjfx/static/js/chunk-c8ec8b4a.e230ecc5.js" rel="prefetch">
module.exports = {
  publicPath: '/nhtjfx/',
（3）nignx配置
 
server {
        listen       8088;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
	location /nhtjfx/ {
	    alias /usr/local/linewell/web/nhjcfx/front/nhtjfx/;
	    index index.html;
	    try_files $uri $uri/ /nhtjfx/index.html;
        #location / {
           # root  /usr/local/linewell/web/nhjcfx/front/nhtjfx;#vue前端项目打包后放在这里   
      #      root  /usr/local/linewell/web/nhjcfx/front/build;
      #      index  index.html index.htm;#这个index.html  是上面dist目录下的index.html
      #	    try_files $uri $uri/ /index.html; # 解决刷新出现404 
     #   }
        #error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
                    把上面的这两行代码
// 创建一个Jackson2JsonRedisSerializer实例，用于序列化Redis的value为JSON格式  
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);   
// 设置Jackson2JsonRedisSerializer使用的ObjectMapper  
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);  
换成以下这一行代码
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(objectMapper, Object.class);
