前後端分離部署，ngnix反向代理

開發環境

前端：

1. vue，axios，proxytable
2. build打包成dist
3. 8084端口

後臺：

1. springboot
2. maven打包成jar包（使用springboot內置的Tomcat）
3. 已部署在8082端口

部署情況

前端：

1. ngnix（nginx安裝、部署測試教程）
2. 已測試連接成功

後臺：

1.安裝好java（1.8）， nohup java -jar XXX.jar &啓動
2. 已測試連接成功

生產環境（問題：前端請求後臺接口時404）

前端config-index.js配置代理

proxyTable: {
      '/api': {
        // target: 'http://127.0.0.1:18891',
        target: 'http://X.X.235.234:8082',
        changeOrigin: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    },

axios.post(/api/index/getlist).then((res)=>{})

前臺請求：/api/index/getlist
相當於
後臺請求：http://X.X.235.234:8082/index/getlist
