啟動Spring Boot應用程序時不考慮數據庫端口

Question

我得到了一個Spring Boot應用程序以進行dockerize。

總覽

• 應用程序是一個Springboot應用程序。
• 使用Gradle構建。
• 使用application.yml的應用程序屬性。
• 數據庫：DBServer：1435（端口不是默認的1433）。

最初，我創建了docker映像並啟動了應用程序。
后來，數據庫端口更改為1435。現在，我已更新位於src \\ main \\ resources中的application.yml中的配置文件的datasource部分中的JDBC url。 啟動Docker映像時會傳遞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

現在應用程序將無法啟動，而是默認為端口1433。錯誤如下。 我不確定為什么默認為1433。有什么想法嗎？

我嘗試從docker機器連接到數據庫實例，並且工作正常。
進一步我檢查使用Telnet和端口1435是否可以連接。

Answer 1

這是一個常見問題，許多Java應用程序嘗試連接到Microsoft SQL Server時都會跳閘。 請按照以下步驟解決您的問題。

1. 打開SQL Server 2014 Configuration Manager 。
2. 在左窗格的“ SQL Server網絡配置 ”下，單擊“ SQLEXPRESS 協議” 。 在右窗格中，右鍵單擊“ TCP / IP” ，然后選擇“ 屬性” 。
3. 在出現的“ TCP / IP屬性”對話框中，單擊“ IP地址”選項卡。
4. 向下滾動以找到IPALL節點。 刪除任何值（如果存在於TCP動態端口），並為TCP Port指定1433 。
5. 單擊確定 。
6. 再次右鍵單擊右窗格中的TCP / IP ，然后選擇啟用 。
7. 在“ SQL Server服務”節點上，右鍵單擊“ SQL Server（SQLEXPRESS）” ，然后選擇“ 重新啟動” 。

您的application.properties中的連接字符串必須如下所示：

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