无法解析对org.springframework.boot.autoconfigure.jdbc的导入

前端开发 2026-07-10

我一直在按这个教程做一个小型网站：https://medium.com/@alexandre.therrien3/java-spring-tutorial-the-only-tutorial-you-will-need-to-get-started-vs-code-13413e661db5

我把MSSQL作为数据库，但在我的DataSourceConfig.java文件中，Spring似乎在连接它时遇到了一些问题：

import org.springframework.boot.autoconfigure.jdbc无法解析。

起初，VS Code的导入那里还有更多错误，因此我执行了mvn install:

mvn install:install-file "-Dfile=sqljdbc4.jar" "-DgroupId=com.microsoft.sqlserver" -DartifactId=sqljdbc4 "-Dversion=4.0" -Dpackaging=jar

解决方案

你在运行时会看到 ClassNotFoundException：DataSourceProperties，这意味着包含它的依赖从 pom.xml 中缺失，或者在这个版本中根本不存在。但幸运的是你并不需要 DataSourceConfig 类。Spring Boot将从 application.properties 自动配置数据源。

这对我有用：

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
</dependency>
