我正在尝试连接到SQL Server，并将数据插入数据库中。我有一个班级人员，主要和DataBaseInfo。我已经为所有错误下载了maven库，但没有成功。我不知道为什么

package test1;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
    //jdbc:sqlserver:10.200.105.11;databaseName=test;integratedSecurity=true
    public static void main(String[] args) {
        ApplicationContext conx = new ClassPathXmlApplicationContext("bean.xml");
        DataBaseInfo di = (DataBaseInfo)conx.getBean("dbi");
        int ins=di.insertPerson(new Person("abdulaziz","riyadh","Saudi","Developer"));
        System.out.println(ins);
    }
}

运行它时，会发生此错误：

您有两个选择。

  1. 在编译Maven模块时使用JDK版本10。自从您提供的例外以来，版本10表示了这一点。类文件格式54对应于Java10。请参见here。

  2. 使用为JDK版本8编译的JDBC驱动程序版本或与您要使用的JDK版本匹配的版本。但是也要检查数据库的文档，以确保选择正确的驱动程序实现。例如：

    <dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>7.0.0.jre8</version>
</dependency>

答案 1 :(得分：0)

尝试从Maven使用低版本的jdbc驱动程序
