【中文标题】尝试连接到 Activiti 的 H2 数据库设置时出现异常【英文标题】：Exception while trying to connect to H2 database setup for Activiti 【发布时间】：2016-02-22 16:20:56 【问题描述】：我正在尝试设置独立的 H2 DB 来试用一些基本的 Activiti 东西。 但是每当我尝试启动 tomcat 时，都会出现异常：

我的 tomcat/webapps/WEB_INF/classes/db.properties 是：
db=h2
jdbc.driver=org.h2.Driver
jdbc.url=jdbc:h2:tcp://localhost/~/test
jdbc.username=sa
jdbc.password=
而我的 activiti.cfg.xml 是：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
<property name="jdbcUrl" value="jdbc:h2:tcp://localhost/~/test" />
<!-- <property name="jdbcUrl" value="jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000" /> -->
<property name="jdbcDriver" value="org.h2.Driver" />
<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />
<property name="databaseSchemaUpdate" value="true" />

<property name="asyncExecutorActivate" value="false" />
<property name="mailServerHost" value="mail.my-corp.com" />
<property name="mailServerPort" value="5025" />
</bean>
</beans>
我的项目层次结构是：
我可以使用凭据 sa/sa 登录 H2 控制台：
编辑#1
我不知道如何设置用户名/密码。我只使用默认设置。
我设法使用凭据 sa/sa 登录到 H2 控制台。
在我的 tomcat/webapps..../db.properties 和 activiti.cfg.xml 我有：
jdbc.username=sa
jdbc.password=
&
<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />
分别。
我还尝试在这两个文件中将密码值设置为“sa”。但在那种情况下，我会得到一个不同的错误：

编辑#2
好的，我刚刚把activiti.cfg.xml中的JdbcUrl从jdbc:h2:tcp://localhost/~/test换成了jdbc:h2:tcp://localhost/~/activiti
并且tomcat现在开始正常，没有错误。不知道发生了什么。
我现在无需密码即可登录 H2 控制台，只需 sa/""，可以使用
我现在可以成功执行我的 BookOrderTest（使用 H2 独立 DB 的测试用例），但由于在 localhost/activiti-explorer web-app 上运行此测试，我仍然看不到正在创建新的排队任务。
有什么想法吗？
谢谢
【问题讨论】：
投反对票的人请花一些时间提供投反对票的原因。 【参考方案1】：我们刚刚遇到了类似的问题。问题是 Activiti 已经带有 h2*.jar 或某个版本。在我们的案例中，服务器和客户端版本不匹配 - 它在启动时导致不断的异常
从 Activiti 的 lib 文件夹中删除 h2*.jar 文件。 将 h2*.jar 从您的 H2 服务器设置复制到 lib。 重启 Tomcat（或任何你有的）【讨论】：
【参考方案2】：来自您的 activit.cfg.xml
<property name="jdbcPassword" value="" />
来自您的 db.properties
jdbc.password=
您说您可以使用 sa/sa 进行连接，但文件中的密码值为空，它必须是“sa”
编辑#1
首先，在 activiti.cfg.xml 和 db.properties 文件中设置密码“sa”。
因为您正在尝试基本的东西，最好从内存数据库开始：h2 in-memory database
刚刚设置：
在您的 db.properties 中：jdbc.url=jdbc:h2:mem:
在您的 activiti.cfg.xml 中：
<property name="jdbcUrl" value="jdbc:h2:mem:"/>
如果您想在混合模式下运行 H2，请阅读 this，指向 mixed mode，我认为这就是您要实现的目标。
混合模式配置：
在您的 db.properties 中：jdbc.url=jdbc:h2:/data/test;AUTO_SERVER=TRUE
在您的 activiti.cfg.xml 中：
<property name="jdbcUrl" value="jdbc:h2:/data/test;AUTO_SERVER=TRUE"/>
【讨论】：
我曾尝试在这些文件中使用 sa 作为密码。有关详细信息，请参阅 EDIT#1。 好吧，当我使用内存数据库时，我的代码可以正常工作。我只有独立数据库的问题。此外，我在独立设置方面也取得了一些进步。有关详细信息，请参阅编辑#3。 在您的 activiti-explorer 项目中，在 activiti-explorer\WEB-INF\classes 下，您会找到相同的db.properties 和 activiti.cfg.xml 文件。将 jdbc url 指向您的数据库
在 activiti-explorer\WEB-INF\classes 我只有 db.properties 文件，更新有 jdbc.url=jdbc:h2:tcp://localhost/~/activiti 导致连接是损坏：“意外状态 16777216”[90067-176] 启动 tomcat 时。
既然您尝试在独立数据库中运行 activti，请查看this activiti's forum link。以上是关于尝试连接到 Activiti 的 H2 数据库设置时出现异常的主要内容，如果未能解决你的问题，请参考以下文章
使用 RobotFramework 连接到 H2 数据库文件
