Question

我正在尝试使用Tomcat在部署和mariaDB作为数据库的帮助下部署应用程序。相应生成的war文件已部署，但当我尝试访问其他页面（基本网址/目标网页除外）时，会显示以下错误：

web-app_1  | 07:20:00.324 [http-apr-8080-exec-3] INFO com.company.controller.MainController - in Main controller
web-app_1  | 07:20:00.806 [http-apr-8080-exec-3] DEBUG org.hibernate.stat.internal.StatisticsInitiator - Statistics initialized [enabled=false]

web-app_1  |    at org.springframework.jdbc.datasource.AbstractDriverBasedDataSource.getConnectionFromDriver(AbstractDriverBasedDataSource.java:196)

和hibernate.properties文件包含：

jdbc.driverClassName = org.mariadb.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/ams_dbnew
jdbc.username = username

jdbc.password = password
hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.hbm2ddl.auto = none
hibernate.format_sql = true
hibernate.show_sql = true

虽然指向jdbc:mysql://localhost:3306/但在tomcat中将其显示错误记录为java.sql.SQLNonTransientConnectionException: Could not connect to address=(host=localhost)(port=833)(type=master) : Connection refused (Connection refused)

并且数据库在相同的3306端口

上运行

sudo netstat -tulpen | grep mysql
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      121        410570      51950/mysqld

谁能告诉我哪里和哪一部分做错了？

和docker-compose文件是：

version: '3'
services:
  web-app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
       - 8080:8080
    network_mode: "host"

Answer 1

我怀疑端口833，尝试搜索号码＆＃34; 833＆＃34;在您的tomcat主目录中

cd /TOMCAT_HOME_DIRECTORY/
grep -rli 833 .

可能是覆盖端口号的文件之一。

无法部署应用程序
