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，我都会遇到一个异常：

我的tomcat / webapps / WEB_INF / classes / db.properties是：

jdbc.driver=org.h2.Driver
jdbc.url=jdbc:h2:tcp://localhost/~/test
jdbc.username=sa
jdbc.password=
我的activiti.cfg.xml是：

我的项目层次结构是：
并且我能够使用凭据sa / sa登录到H2控制台：
编辑＃1
我不确定如何设置用户名/密码。我仅使用默认设置。
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中，我有：
jdbc.username=sa
jdbc.password=
和
<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />
分别。
我还尝试了在这两个文件中将密码值设置为“ sa”。但是在那种情况下，我得到了另一个错误：

编辑＃2
好的，我只是将activiti.cfg.xml中的JdbcUrl从
jdbc:h2:tcp://localhost/~/test替换为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。
我现在登录到H2控制台时没有密码，只是sa /“”，可以
现在，我可以成功执行BookOrderTest（使用H2独立DB的测试用例），但是由于此测试在
localhost/activiti-explorer Web-app上运行，因此我仍然看不到正在创建新的排队任务。有什么想法吗？
谢谢
最佳答案
我们只是面临类似的问题。问题在于Activiti已经带有h2 * .jar或某些版本。在我们的情况下，服务器和客户端版本不匹配-启动时会导致不断的异常
从Activiti的lib文件夹中删除eve2 h。*。jar文件。
将H2 * .jar从H2服务器设置复制到lib中。
重新启动Tomcat（或任何现有的）
