Camunda 7.2 上的历史级别不匹配

Question

我按照官方网站上的指南将 camunda.war (7.2) 部署到我的普通 tomcat7 中。

现在当我启动tomcat时出现以下错误：

GRAVE: Error while closing command context
org.camunda.bpm.engine.ProcessEngineException: historyLevel mismatch: configuration says org.camunda.bpm.engine.impl.history.HistoryLevelAudit@21 and database says 3

在数据库（ACT_GE_PROPERTY 表）中，historyLevel 设置为 3 这是我的 bpm-platform.xml 文件

    <?xml version="1.0" encoding="UTF-8"?>
<bpm-platform xmlns="http://www.camunda.org/schema/1.0/BpmPlatform"

    </properties>

Answer 1

您是否从 camunda.org/download 下载了 Tomcat 的“camunda 独立 web 应用程序”WAR？

如果是这样，您应该通过将

<property name="history" value="full"/>

添加到流程引擎配置 bean

<bean id="processEngineConfiguration" class="org.camunda.bpm.engine.spring.SpringProcessEngineConfiguration>

来调整“application-context.xml”文件内的历史级别。

否则，你写下将

camunda.war

安装到普通 Tomcat 却发布了对

bpm-platform.xml

文件的引用，这很奇怪，当你不使用共享流程引擎方法时，该文件根本不会被使用。

Answer 2

要更改 Spring Boot 应用程序中的历史级别，您应该在两个地方更改配置 首先更改 ACT_GE_PROPERTY 表中的历史级别。

//NONE(0), ACTIVITY(1), AUDIT(2), FULL(3)
//default is FULL(3)
update act_ge_property set VALUE_ = '1' where NAME_ = 'historyLevel';

在第二步中，您应该将 application.yml 文件中的默认历史级别配置更改为：

camunda.bpm.history-level: ACTIVITY
