为 SQL Server 创建数据源的 Spring 错误

【问题标题】：Spring error creating DataSource for SQL Server为 SQL Server 创建数据源的 Spring 错误
【发布时间】：2017-04-17 20:42:23
【问题描述】：

我正在使用 DataAccess（使用 Spring）构建一个 WebApi。我有一个 bean 来创建这样的数据源：

@Bean
public DataSource getDataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    dataSource.setUrl("jdbc:sqlserver://localhost/DawDB");
    dataSource.setUsername("root");
    dataSource.setPassword("P@ssw0rd");

    return dataSource;
}

但每次我尝试运行应用程序时都会得到：

Could not load JDBC driver class
[com.microsoft.sqlserver.jdbc.SQLServerDriver]

我已经尝试添加 jar 文件 throw gradle 并手动添加为外部库。

我错过了什么吗？

编辑：

在 gradle 上，我正在添加依赖项：

compile('com.microsoft.sqlserver:sqljdbc4:4.0')

编辑2：

正如我所解释的，我已经尝试将 jar 文件添加到我的外部库中。

完整的堆栈跟踪：

启动 ApplicationContext 时出错。要显示自动配置报告，请在启用“调试”的情况下重新运行您的应用程序。

【问题讨论】：

  • 你是如何在你的 gradle 中添加驱动程序的？
  • @Alfabravo 已编辑 ;)
  • Missing artifact com.microsoft.sqlserver:sqljdbc4:jar:4.0... 的可能重复消息不一样，但您可能需要自己获取驱动程序这一事实可能会有所帮助。
  • 我正在使用 Gradle，但我也已经手动添加了 jar 文件
  • 一切都指向你的类路径，不包括库。您可能已经添加了它，但编译的项目设置没有添加它。 ://

标签： java spring spring-mvc jdbc


【解决方案1】：

有同样的问题，但对我来说添加了 com.microsoft.sqlserver:mssql-jdbc 依赖项。
您正在使用的 Java 版本。
他们为每个人提供了合辑：7.4.1.jre8
