因此，基本上，我在尝试连接到数据库时得到java.lang.NoClassDefFoundError: javax/net/SocketFactory
。我正在使用mvn回购中的mariadb驱动程序。
<dependency>
<groupId>org.mariadb.jdbc</groupId>
<artifactId>mariadb-java-client</artifactId>
<version>2.3.0</version>
</dependency>
这是我的代码：
try{
DriverManager.registerDriver(new org.mariadb.jdbc.Driver());
}catch (SQLException e){
logService.log(LogService.LOG_ERROR, "Error while registering driver.");
}
try (Connection connection = DriverManager.getConnection("jdbc:mariadb://myhost:myport/mydb?allowMultiQueries=true", "admin", "password")) {
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery(queryString);
我的代码或配置有问题吗？
编辑：完整堆栈跟踪

结果证明javax.net软件包未包含在OSGi捆绑软件中。自从我们之前使用MySQL JDBC驱动程序以来，这引起了很多混乱，我想它具有SocketFactory的自己的实现，而MariaDB驱动程序显然没有。
答案 1 :(得分：0)
确保您正在使用jdk，并且jdk没有损坏。它必须在jdk1.8.0_xyz \ jre \ lib目录中包含jsse.jar。参见https://www.oracle.com/technetwork/java/jsse-136410.html进行手动下载（在全新安装中这不是必需的，我宁愿重新安装jdk）。
答案 2 :(得分：0)
此问题已解决，但如果其他人遇到相同的错误。
如果在插件中遇到此错误，则只需导入pom文件的 标签下的 javax.net 。
