运行OfBiz时出错-HTTP状态500 –内部服务器错误

Question

我在运行Ofbiz时遇到问题，它将引发此错误：

HTTP状态500 –内部服务器错误类型异常报告

消息无法获取序列名称的下一个序列ID：访问

描述服务器遇到意外情况，阻止其满足请求。

例外

java.lang.IllegalArgumentException: Could not get next sequenced ID for sequence name: Visit

注意在服务器日志中可以找到根本原因的完整堆栈跟踪。

Apache Tomcat / 9.0.13

我已经研究了此错误，它似乎与我的委托人或与数据库的连接有关，但是我不具备修复此错误的技能。 有人可以帮帮我吗？

我已经发布了我的entityengine.xml的内容

Answer 1

原因很容易解释：您正在自动生成ID，这些ID已经被使用。 这将导致该条目的回滚，然后引发后续错误。

您最有可能导入了IDs大于10000的种子数据，这是大多数自动ID开始的位置，现在新条目将与现有ID冲突。

您可以通过更新nextseqId值（有一个表）来解决此问题。

有关此主题的更多信息，请随时加入Scipio ERP社区 ，该社区恰好是OFBiz项目的一个现代分支，

Answer 2

在您为entityengine.xml附加的代码中没有看到您的第一个<delegator>开头标记。 假设您正在使用MySQL数据库，请检查<datasource name="localmysql">提供的数据库名称，用户名，密码等详细信息是否正确。 另外，请检查您是否能够在Ofbiz之外访问数据库。 即通过像SQL Yog这样的数据库客户端。
