为SQL Server创建DataSource的Spring错误

时间:2017-04-17 20:42:24

标签: java spring spring-mvc jdbc

我正在使用DataAccess(使用Spring)构建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我都会:

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上我添加了依赖项:

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

Edit2:

正如我解释的那样,我已经尝试将jar文件添加到我的外部库中。

完成堆栈跟踪:

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

答案 0 :(得分:0)

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心理版本。
他们每个人都有共同点:7.4.1.jre8
