从 DbVisualizer 连接到 H2 服务器

【问题描述】：

我的 H2 数据库配置如下：

@Configuration
@Profile({ Profiles.DEV })
public class DevDataSourceConfiguration {

    @Bean(initMethod = "start", destroyMethod = "stop")
    public Server h2WebServer() throws SQLException {
        return Server.createWebServer("-web", "-webAllowOthers", "-webPort", "8082");
    }

    @Bean(initMethod = "start", destroyMethod = "stop")
    @DependsOn("h2WebServer")
    public Server h2Server() throws SQLException {
        return Server.createTcpServer("-tcp", "-tcpAllowOthers", "-tcpPort", "9092");
    }

    @Bean
    @DependsOn("h2Server")
    public DataSource datasource() {
        HikariDataSource ds = new HikariDataSource();
        ds.setDriverClassName("org.h2.Driver");
        ds.setJdbcUrl("jdbc:h2:tcp://localhost/~/bignibou");
        return ds;
    }
}

我现在尝试使用以下 jdbc URL 从 DBVisualizer 访问我的数据库：jdbc:h2:tcp://localhost/~/bignibou，我在 dbvis 日志中收到以下错误：

edit 2：我也注意到了这一点（在应用程序控制台日志中）：

【问题讨论】：

  • 临时将“;trace_level_system_out=3”附加到数据库 URL 可能有助于调试目的
  • HI AydinK：我已经编辑了我的帖子。
  • DBVisualizer 是用 Java 实现的。你能通过普通的旧 jdbc 连接到数据库吗？
  • 是的，我正在使用 jdbc 连接到数据库。我认为这是使用 dbvis 的唯一方法。
  • 我注意到两件事：显然在设置 auto_commit 连接参数时引发了异常，并且您显然正在将 tcp 与连接字符串中的本地访问混合。尝试将连接字符串更改为 jdbc:h2:tcp://localhost:9092。

【解决方案1】：

我有同样的问题。我从http://h2database.com 安装了 H2，并且 grails 应用程序正在抛出：

[localhost-startStop-1] ERROR StackTrace  - Full Stack Trace:
org.h2.jdbc.JdbcSQLException: Connection is broken: "java.net.ConnectException: Connection refused: connect: localhost" [90067-176]

事实证明，我的 H2 服务器版本是 1.4.196，我将 1.3.176 作为 grails 依赖项加载。我已更新 BuildConfig.groovy 以使其工作：

dependencies {
    ...
    test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"
    runtime "com.h2database:h2:1.4.196"
}

【讨论】：

    【解决方案2】：
    • 最新的 H2 稳定版本：1.3.176。
    • 最新的 dbVisualizer H2 驱动程序：1.3.176。

    您可能正在使用 H2 (1.4.x) 的 beta 版本，在客户端/服务器通信中存在一些错误（版本不匹配应该不是问题，因为客户端和服务器协商使用哪个协议版本）尝试使用H2 的最新 beta 版本或使用 H2 的最新稳定版本。

    【讨论】：

    • 就是这样：我只需要从 1.4.xx 更改为 1.3.176，现在就可以正常工作了。
    【解决方案3】：

    检查您在 DBVisualizer 中使用的 h2 JDBC 驱动程序的版本。具体来说，检查是否与您在服务器上使用的版本匹配。虽然版本匹配通常无关紧要，但不久​​前 H2 存在问题，在使用不匹配的版本时会导致此类错误。

    如果这没有帮助，您可能还想准确报告您在客户端和服务器上使用的 H2 版本。

    【讨论】：

    • 它很脆。如果 H2 JDBC 驱动程序与服务器端的驱动程序不匹配，则您会收到错误消息“连接断开：”“意外状态 16777216”。这是一条神秘的错误信息。
