我在访问 wso2 esb 管理控制台时遇到问题：版本 4.5.1

当我登录控制台时，我得到一个很大的堆栈跟踪，并且无法访问在 esb 上运行的任何功能/服务。

有人可以帮忙吗？

下面的堆栈跟踪：

这可能是由于服务元文件损坏所致。您可以尝试以下步骤。

  1. 关闭服务器
  2. 备份以下目录。/存储库/部署/服务器/服务元文件
  3. 删除上述目录的内容。
  4. 启动服务器。

似乎问题发生在您使用 H2 数据库并且 wso2 进程被突然终止时。

在我的情况下，我正在使用 Eclipse 调试 .arr 服务（RemoteProvisioningServiceWS.aar），并且 wso2 在调试模式下启动，eclipse 突然冻结，我不得​​不杀死 eclipse 和 wso2。当我尝试重新启动 wso2 时，我正在调试的 .arr 显然没有正确加载。

如果您尝试在 wso2 Web 控制台中打开服务列表，则会出现错误：

看来是数据库的问题，我不建议在开发和生产环境中使用h2 db并在mySql中配置wso2，只在本地使用h2。

解决问题：下载相同版本的 wso2 解压并再次复制或安装所有服务和应用程序，重新启动，一切都会再次正常。

首先检查，您是否有任何数据库连接，该数据库是否已关闭。

如果没问题，再次访问 www.wso2.org，然后下载新的 zip 文件，并将所有服务转移到该服务器。检查数据库是否工作，然后启动服务器。

希望这会帮助你，任何疑问让我知道..
