我的要求是在以嵌入式模式部署我的战争文件时应该启动 H2 数据库。为此，我在我的 java 项目中创建了 class(DbSetup)。我在 web.xml 中提到了同一个类。然后我实现了 contextInitialized(ServletContextEvent sce) 方法。在这种方法中，我正在连接到在部署战争时建立连接的 h2 db。在获取战争文件时，我得到了类似“没有为 jdbc:h2:~/test1 找到合适的类。请问如何解决这个问题？我正在将 h2-1.4.192.jar 与我的战争绑定。我还复制了相同的 jar 到类路径。

我的课：

try 
{

        Connection connection = null;
        final String DB_CONNECTION = "jdbc:h2:~/test1";

        final String DB_USER = "sa";
                 Class.forName(org.h2.Driver);

        final String DB_PASSWORD = "sa";
        connection = DriverManager.getConnection(DB_CONNECTION, DB_USER, DB_PASSWORD);
        return connection;
