Spring Boot-SQL Server连接问题（ExistingValue必须是javax.sql.DataSource的实例）
[英]Spring boot - Sql Server connection issue(ExistingValue must be an instance of javax.sql.DataSource)
问题描述
我正在尝试使用构造函数注入模型将Spring Boot与sql server（localhost）连接。 我遇到了问题。 你能帮我检查一下吗？
“ ExistingValue必须是javax.sql.DataSource的实例”-最后添加了完整的错误日志。 请找到。
我能够在sql server management studio中连接sql server（localhost）并检查tcp端口已启用。
如果我删除了与数据库连接有关的内容-静态数据门户网站正常运行。
我尝试了各种修复程序，例如
- 更改pom中的最新罐子
- 尝试将localhost替换为comp.url中的计算机名称
- 已验证的数据库服务器运行状态
的pom.xml

您正在使用DataSourceBuilder构建DataSource ，该DataSource要求您在类路径中具有以下连接池之一：HikariCP，Tomcat或Commons DBCP（请参阅javadoc ）。
因此，尝试在pom.xml添加其中之一（例如HikariCP ）：
<dependency>
<groupId>com.zaxxer</groupId>
<artifactId>HikariCP</artifactId>
</dependency>

尝试使用spring-boot-starter-data-jpa依赖项，配置连接属性，Spring Boot将负责创建DS
