Question

我已经获得了一个用于dockerize的Spring启动应用程序。

概述

应用程序是一个Springboot应用程序。
使用Gradle构建。
使用application.yml的应用程序属性。
数据库：DBServer：1435（端口不是默认值1433）。

最初我创建了泊坞窗图像并启动了应用程序之后，DB端口更改为1435.现在，我已更新位于src \ main \ resources中的application.yml中的配置文件的数据源部分中的JDBC URL。启动docker镜像时会传递DB_IP和DB_NAME。

spring:
  profiles: dev,staging,prod
  datasource:
    url: "jdbc:sqlserver://${DB_IP}:1435;databaseName=${DB_NAME}"
    username: "${DB_USER}"
    password: "${DB_PASS}"
    initialize: false
  jpa:
    show-sql: true
    generate-ddl: false
    hibernate:
      ddl-auto: none

现在应用程序无法启动而是默认为端口1433.错误如下所示。我不知道为什么它会违约到1433.任何想法？

我尝试从docker机器连接数据库实例，但工作正常此外，我使用Telnet进行了检查，并且可以连接端口1435.

这是一个常见问题，导致许多试图连接到Microsoft SQL Server的Java应用程序出现问题。以下步骤将解决您的问题。

打开 SQL Server 2014 Configuration Manager 。
点击左侧窗格中 SQL Server网络配置下的 SQLEXPRESS 的协议。在右侧窗格中，右键单击 TCP / IP ，然后选择属性。
在显示的 TCP / IP 属性对话框中，点击 IP地址标签。
向下滚动以找到 IPALL 节点。删除 TCP动态端口时的任何值，并为 TCP端口指定 1433 。
点击确定。
再次右键单击右侧窗格中的 TCP / IP ，然后选择启用。
在 SQL Server服务节点上，右键单击 SQL Server（SQLEXPRESS），然后选择重新启动。

application.properties中的连接字符串必须如下所示：

spring.datasource.url=jdbc:sqlserver://localhost;databaseName=YourDBName

启动Spring启动应用程序时不考虑DB端口
