连接到 wso2 esb 管理控制台的功能/服务的问题 - esb 版本 4.5.1

Question

我在访问 wso2 esb 管理控制台时遇到问题：版本 4.5.1

当我登录到控制台时，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？

Answer 1

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。 /repository/deployment/server/servicemetafiles
3. 删除上述目录的内容。
4. 启动服务器。

Answer 2

首先检查，您是否有任何数据库连接，是否有数据 基地已关闭。

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 醒不醒，然后启动服务器。

希望对你有帮助，如有疑问请告诉我..

Answer 3

好像是在使用H2数据库时出现了问题，wso2进程突然被杀掉了。

在我的情况下，我正在调试一个 .arr 服务 (RemoteProvisioningServiceWS.aar)，其中 eclipse 和 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 控制台打开服务列表，则会出现错误：

好像是数据库的问题，开发和生产环境不建议使用h2 db，在mySql中配置wso2，只能在本地使用h2。

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