[英]Deploying Spring MVC web app .war file in tomcat in openshift results in blank page
[英]Deploying Web App With Spring MVC
我从来没有遇到过这个问题。 实际上,我有一个通过war文件运行的Web应用程序。 我已经配置了Spring来使用它,并且它可以完美地工作。
问题是我试图通过Spring配置Activiti。 基本上,WEB-INF / processes文件夹中有一组.bpmn20.xml文件。 Activiti团队提到他们不知道如何在Web应用程序中进行配置。 作为一个独立的应用程序,我可以自动部署资源.bpmn20.xml文件,因为processs文件夹位于类路径上。 我在网络应用程序结构中配置时遇到麻烦。
请看下面:
我通过运行DbSchemaCreate.main()创建了Spring MVC应用程序并创建了Activiti数据库。 实际上,我的流程似乎没有部署在war文件上。 Tomcat启动时,ProcessEngine将通过Spring启动并运行。 我可以访问RuntimeService。 该代码可以在下面看到:

没有部署自动资源部署。 我也尝试通过代码进行部署,但是会引发异常:
repositoryService.createDeployment().addClasspathResource("ProcessExample.bpmn20.xml").deploy();
runtimeService.startProcessInstanceByKey("processExample", mapOfProcessVariables);

该资源如何位于Webapp内部?
我尝试将其放在WEB-INF / processes / ProcessExample.bpmn20.xml中。
我也尝试过:
<property name="deploymentResources" value="/WEB-INF/processes.*.bpmn20.xml"/>
编辑
该网站可能会有所帮助,但我被困住了。
也许尝试将定义了过程的文件夹(您的bpmn20.xml文件)添加到构建路径中 。
该错误告诉您,Activiti-Engine无法找到您的文件,这就是为什么您需要告诉它在哪里可以找到它的原因。
尝试这个 :

上面的代码是spring-config.xml
在src文件夹的resources文件夹中添加database.properties文件。 因此,在database.properties中编写代码
database.driver=com.mysql.jdbc.Driver database.url=jdbc:mysql://localhost:3306/apmc_db database.user=root database.password= hibernate.show_sql=true
