启动 Spring Boot 应用程序时出现数据库异常

问题描述 投票：0回答：1

我正在使用 mssql 连接的自定义端口，一切似乎都正确，但是当我启动应用程序时，出现以下异常。

Caused by: org.hibernate.exception.JDBCConnectionException: Unable to open JDBC Connection for DDL execution [The TCP/IP connection to the host localhost:1434, port 1433 has failed. Error: "localhost:1434. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".] [n/a]

下面是application.yml

spring:
  jpa:
    hibernate:
      ddl-auto: validate
    database-platform: org.hibernate.dialect.SQLServerDialect
  datasource:
    url: jdbc:sqlserver://;serverName=localhost:1434;databaseName=trading;encrypt=false
    username: trading
    password: trading
    driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver

数据库在本地运行，可以连接SQL编辑器。异常看起来与连接有关，但不确定出了什么问题。

java spring spring-boot spring-data-jpa mssql-jdbc

根据文档，

serverName
属性不支持端口号：

  • serverName
    （可选）- 是要连接的服务器的地址。该地址可以是 DNS 或 IP 地址，也可以是本地计算机的 
    localhost
    或 
    127.0.0.1
    。如果未在连接 URL 中指定，则必须在属性集合中指定服务器名称。

然而，还有另一个属性称为

portNumber
：

  • **
    portNumber
    （可选）- 是要连接到 
    serverName
    上的端口。默认为 
    1433
    。如果您使用默认端口，则不必指定端口，也不必在 URL 中指定前面的 
    :
    。

所以解决方案是使用以下网址：

jdbc:sqlserver://;serverName=localhost;portNumber=1434;databaseName=trading;encrypt=false
