Question

我正在使用wildfly 14.0.1应用服务器和Camunda V 7.11.0。我已经配置了mysql db而不是默认的camunda h2 db，并将以下数据源添加到了standalone.xml文件中。但是我在部署时遇到了以下异常。如何解决此异常？

        let parameters = ["fields": "email, id, name"]
        let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: parameters)

        _ = graphRequest?.start { [weak self] connection, result, error in
            // If something went wrong, we're logged out
            if (error != nil) {
                // Clear email, but ignore error for now
                return
            }

            // Transform to dictionary first
            if let result = result as? [String: Any] {
                // Got the email; send it to Lucid's server
                guard let email = result["email"] as? String else {
                    // No email? Fail the login
                    return
                }
                guard let username = result["name"] as? String else {
                    // No username? Fail the login
                    return
                }

                guard let userId = result["id"] as? String else {
                    // No userId? Fail the login
                    return
                }                       
            }
        } // End of graph request

我使用mysql-connector-java-5.1.44.jar而不是5.1.6版本来修复该异常。

如何修复“使用元数据已经存在的表” Camunda Process Engine异常？
