Java 无法与SQL Server 2014建立连接-创建bean时出错

我有一个微型服务，它连接到数据库并返回一个string类型的对象。当我尝试运行应用程序时，我看到一个bean创建错误| |错误创建名为dataSource的bean。我尝试了stackoverflow中提到的几个选项，但无法解决问题，这让我不得不发布这个问题。下面是错误、应用程序属性和POM。如有任何建议，我们将不胜感激

注: 使用了Java6、Spring引导

谢谢

错误

INFO: JSR 356 WebSocket (Java WebSocket 1.1) support is not available when running on Java 6. To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocket JARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties. Note that the deprecated Tomcat 7 WebSocket API will be available.

看起来您的SQL Server驱动程序仅在测试范围内加载：

测试

---

如果您试图运行应用程序本身，则需要将其包含在运行时类路径中。只要删除该范围声明，它就可以工作。

应用程序中没有SQL Server JDBC驱动程序。原因是您已在POM中指定此依赖项的范围为

test

。要解决此问题，请删除SQL Server JDBC驱动程序的

test

，然后重新编译并重新部署

另外，最新版本的SQLServerJDBC驱动程序是

com.microsoft.sqlserver
mssql jdbc
6.2.2.jre8

谢谢您的回复。我删除了范围并尝试了，我看到了相同的问题。你还有其他建议吗？新版本的JDBC驱动程序需要Java8吗？因为我现在正在使用java 6。@sandy您重新导入/重新编译了吗？无论如何，最新版本只有Java8或Java7（使用6.2.2.jre7时）。我建议您升级到更新的Java版本。否则，请仔细检查构建是否包含驱动程序。是的，我重新编译了应用程序。我还检查了jar，它实际上存在于.m2/repo中。在升级到Java7/8时，我几乎没有什么限制。springboot版本有什么问题吗？或者这只是因为对于sql jdbc？@sandy，您需要检查它是否包含在spring boot应用程序中，而不是它是否包含在本地maven存储库中。是的，它也包含在应用程序构建路径中。你能检查一下这个错误是否有其他可能吗？这是因为tomcat还是其他版本？谢谢你的回复。我删除了范围并尝试了，我看到了相同的问题。你还有其他建议吗？
