无法从数据源确定 jdbc url；无法获取用于提取元数据的连接

Question

我正在创建一个新的 springboot 应用程序并尝试与 Sql Server 连接。但无法获得连接，我一直在通过互联网尝试很多解决方案，但没有任何效果。

以下是我得到的例外：

2018-08-25 05:55:52 INFO  com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Starting...
2018-08-25 05:56:23 ERROR com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Exception during pool initialization.

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.".

Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host RRI2SQLPW14V, port 1433 has failed. Error: "Invalid argument: create. 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.".

下面是application.properties的配置：

spring.datasource.url=jdbc:sqlserver://RRI2SQLPW14V\\SQL12EEP1:1433
spring.datasource.username=xxxxx
spring.datasource.password=xxxxx
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2008Dialect
spring.jpa.hibernate.ddl-auto = validate

下面是我的 pom.xml

请查看并帮助我连接到 DB。我不确定我在这里做错了什么。

注意：数据库没有防火墙层。

Answer 1

似乎是您的 application.properties 文件中的一个问题。

异常清楚地说：

Unable to determine jdbc url from datasource

以如下方式更改数据源 url 属性： spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=springbootdb

Answer 2

你可以看到enter link description here： 或者使用下面的 URL，以防上面的 URL 不起作用：

jdbc.url=jdbc:sqlserver://<hostname>;instanceName=<instance_name>;databaseName=<database_name>;
