Question

我正在尝试设置独立的H2 DB以尝试一些基本的Activiti内容。但每当我尝试启动tomcat时，我都会遇到异常：

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=

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="jobExecutorActivate" value="false" />
    <property name="asyncExecutorEnabled" 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：

我可以使用凭证sa / sa登录H2控制台：

修改＃1

我不确定如何设置用户名/密码。我只使用默认设置。

我设法使用凭证sa / sa登录H2控制台。

在我的tomcat / webapps .... / db.properties和activiti.cfg.xml中我有：

jdbc.username=sa
jdbc.password=

＆安培;

<property name="jdbcUsername" value="sa" />
<property name="jdbcPassword" value="" />

分别

我还试过将密码值设置为＆＃34; sa＆＃34;在这两个文件中。但在那种情况下，我得到了一个不同的错误：

修改＃2

好的，我刚刚将activiti.cfg.xml中的JdbcUrl从jdbc:h2:tcp://localhost/~/test替换为jdbc:h2:tcp://localhost/~/activiti 和tomcat现在开始很好，没有错误。不确定发生了什么。我现在登录H2控制台没有密码只是sa /＆＃34;＆＃34;，工作

我现在可以成功执行我的BookOrderTest（使用H2独立数据库的测试用例）但是由于在localhost/activiti-explorer web-app上运行此测试，我仍然无法看到正在创建的新排队任务。有什么想法吗？

由于

Answer 1

我们刚遇到了类似的问题。问题是Activiti已经附带了h2 * .jar或某些版本。在我们的案例中，服务器和客户端版本并不匹配 - 它在启动时导致常量异常

从Activiti的lib文件夹中删除h2 * .jar文件。
将H2服务器设置中的h2 * .jar复制到lib。
重启Tomcat（或任何你拥有的）

Answer 2

来自您的activit.cfg.xml

<property name="jdbcPassword" value="" />

来自db.properties

jdbc.password=

你说你可以使用sa / sa连接，但文件中有空密码值，它必须是＆＃34; sa＆＃34;

编辑＃1

首先，设置密码＆＃34; sa＆＃34;在activiti.cfg.xml和db.properties文件中。

因为你正在尝试基本的东西，所以最好从内存数据库开始：h2 in-memory database

刚设置：

： jdbc.url=jdbc:h2:mem:
： <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，我认为这是您尝试实现的目标。

混合模式配置：

db.properties中的

： jdbc.url=jdbc:h2:/data/test;AUTO_SERVER=TRUE
： <property name="jdbcUrl" value="jdbc:h2:/data/test;AUTO_SERVER=TRUE"/>

尝试连接到Activiti的H2数据库设置时出现异常
