使用Spring MVC部署Web App

Question

我從來沒有遇到過這個問題。 實際上，我有一個通過war文件運行的Web應用程序。 我已經配置了Spring來使用它，並且它可以完美地工作。

問題是我試圖通過Spring配置Activiti。 基本上，WEB-INF / processes文件夾中有一組.bpmn20.xml文件。 Activiti團隊提到他們不知道如何在Web應用程序中進行配置。 作為一個獨立的應用程序，我可以自動部署資源.bpmn20.xml文件，因為processs文件夾位於類路徑上。 我在網絡應用程序結構中配置時遇到麻煩。

請看下面：

我通過運行DbSchemaCreate.main（）創建了Spring MVC應用程序並創建了Activiti數據庫。 實際上，我的流程似乎沒有部署在war文件上。 Tomcat啟動時，ProcessEngine將通過Spring啟動並運行。 我可以訪問RuntimeService。 該代碼可以在下面看到：

web.xml

沒有部署自動資源部署。 我也嘗試通過代碼進行部署，但是會引發異常：

 repositoryService.createDeployment().addClasspathResource("ProcessExample.bpmn20.xml").deploy();
 runtimeService.startProcessInstanceByKey("processExample", mapOfProcessVariables);

該資源如何位於Webapp內部？

我嘗試將其放在WEB-INF / processes / ProcessExample.bpmn20.xml中。

我也嘗試過：

<property name="deploymentResources" value="/WEB-INF/processes.*.bpmn20.xml"/>

編輯

該網站可能會有所幫助，但我被困住了。

WEB-INF是否在CLASSPATH中？

Answer 1

也許嘗試將定義了過程的文件夾（您的bpmn20.xml文件）添加到構建路徑中 。

該錯誤告訴您，Activiti-Engine無法找到您的文件，這就是為什么您需要告訴它在哪里可以找到它的原因。

Answer 2

嘗試這個 ：

上面的文件是web.xml

 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <context:component-scan base-package="com.apmc.dao" /> <context:component-scan base-package="com.apmc.services" /> <task:annotation-driven executor="taskExecutor" scheduler="taskScheduler" /> <task:executor id="taskExecutor" pool-size="1" /> <task:scheduler id="taskScheduler" pool-size="1" /> <context:component-scan base-package="com.apmc.controller" /> <context:component-scan base-package="com.apmc.rest" /> <context:property-placeholder location="classpath:database.properties" /> <context:property-placeholder location="classpath:log4j.properties" /> <mvc:resources mapping="/resources/**" location="/resources/mytheme/" /> <mvc:annotation-driven /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${database.driver}" /> <property name="url" value="${database.url}" /> <property name="username" value="${database.user}" /> <property name="password" value="${database.password}" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="annotatedClasses"> <list> <value>com.apmc.domain.Vehicle</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">false</prop> <prop key="hibernate.use_sql_comments">false</prop> </props> </property> </bean> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"> <value>/WEB-INF/pages/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basename" value="/WEB-INF/messages" /> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans> 

上面的代碼是spring-config.xml

在src文件夾的resources文件夾中添加database.properties文件。 因此，在database.properties中編寫代碼

 database.driver=com.mysql.jdbc.Driver database.url=jdbc:mysql://localhost:3306/apmc_db database.user=root database.password= hibernate.show_sql=true
