整合SSH(Struts2、Spring、Hibernate)和JBPM4.4

第一步：导入所需jar包：

具体所需jar包见附件图片

第二步：修改jbpm配置文件：

1、src目录下建立jbpm.cfg.xml（注意注释部分）

<?xml version="1.0" encoding="UTF-8"?>  
<jbpm-configuration>  
    <process-engine-context>  
        <string name="spring.cfg" value="applicationContext.xml" />  
    </process-engine-context> 
    <import resource="jbpm.default.cfg.xml" />  
    <import resource="jbpm.tx.spring.cfg.xml" />  
    <import resource="jbpm.jpdl.cfg.xml" />  
    <import resource="jbpm.bpmn.cfg.xml" />  
    <import resource="jbpm.identity.cfg.xml" />  
    <import resource="jbpm.businesscalendar.cfg.xml" />  
    <import resource="jbpm.console.cfg.xml" /> 
    <import resource="jbpm.spring.default.cfg.xml"/> 
    <!--    
    <import resource="jbpm.jobexecutor.cfg.xml" />  
    -->  
</jbpm-configuration>

2、src目录下建立jbpm.spring.default.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>  
  
<jbpm-configuration>  
  
  <process-engine-context>  
  
    <repository-service />  
    <repository-cache />  
    <execution-service />  
    <history-service />  
    <management-service />  
    <identity-service />  
    <task-service />  
<!--  
    <hibernate-configuration>  
      <cfg resource="jbpm.hibernate.cfg.xml" />  
    </hibernate-configuration>  
  
    <hibernate-session-factory />  
-->  
    <script-manager default-expression-language="juel"  
                    default-script-language="juel"  
                    read-contexts="execution, environment, process-engine"  
                    write-context="">  
      <script-language name="juel" factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />  
    </script-manager>  
  
    <authentication />  
  
    <id-generator />  
    <types resource="jbpm.variable.types.xml" />  
  
    <address-resolver />  
  
    <business-calendar>  
      <monday    hours="9:00-12:00 and 12:30-17:00"/>  
      <tuesday   hours="9:00-12:00 and 12:30-17:00"/>  
      <wednesday hours="9:00-12:00 and 12:30-17:00"/>  
      <thursday  hours="9:00-12:00 and 12:30-17:00"/>  
      <friday    hours="9:00-12:00 and 12:30-17:00"/>  
      <holiday period="01/07/2008 - 31/08/2008"/>  
    </business-calendar>  
  
    <mail-template name='task-notification'>  
      <to users="${task.assignee}"/>  
      <subject>${task.name}</subject>  
      <text><![CDATA[Hi ${task.assignee}, 
Task "${task.name}" has been assigned to you. 
${task.description} 
 
Sent by JBoss jBPM 
]]></text>  
    </mail-template>  
  
    <mail-template name='task-reminder'>  
      <to users="${task.assignee}"/>  
      <subject>${task.name}</subject>  
      <text><![CDATA[Hey ${task.assignee}, 
Do not forget about task "${task.name}". 
${task.description} 
 
Sent by JBoss jBPM 
]]></text>  
    </mail-template>  
  
  </process-engine-context>  
  
  <transaction-context>  
    <repository-session />  
    <db-session />  
  
    <message-session />  
    <timer-session />  
    <history-session />  
    <mail-session>  
      <mail-server>  
        <session-properties resource="jbpm.mail.properties" />  
      </mail-server>  
    </mail-session>  
  </transaction-context>  
  
</jbpm-configuration>

第三步：修改Spring配置文件

1、applicationContext.xml中加入springHelper配置，作为jbpm processEngine的factory bean

<bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper">
		<property name="jbpmCfg" value="jbpm.cfg.xml" />
	</bean>

2、applicationContext.xml中加入processEngine配置，并以此为factory bean创建JBPM本身的各种Service

<bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine"  />
	
	<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/>
	<bean id="executionService" factory-bean="processEngine" factory-method="getExecutionService"/>
	<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService"/>
	<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/>
	<bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService"/>

 3、applicationContext.xml的hibernate配置中加入jbpm所需的hbm.xml配置

<property name="mappingLocations">
			<list>
				<value>classpath:jbpm.execution.hbm.xml</value>
				<value>classpath:jbpm.history.hbm.xml</value>
				<value>classpath:jbpm.identity.hbm.xml</value>
				<value>classpath:jbpm.repository.hbm.xml</value>
				<value>classpath:jbpm.task.hbm.xml</value>
			</list>
		</property>

 4、完整的applicationContext.xml（包括其余DataSource、SessionFacotry、事务控制等）

applicationContext.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:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"
	default-lazy-init="true">
	<import resource="serviceContext.xml" />

	<bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper">
		<property name="jbpmCfg" value="jbpm.cfg.xml" />
	</bean>

	<bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine"  />
	
	<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/>
	<bean id="executionService" factory-bean="processEngine" factory-method="getExecutionService"/>
	<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService"/>
	<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/>

	<bean id="mainDataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close">
		<property name="driverClass" value="oracle.jdbc.driver.OracleDriver" />
		<property name="jdbcUrl" value="jdbc:oracle:thin:@XXXXX:1521:XE" />
		<property name="username" value="jbpm4" />

		<property name="preparedStatementCacheSize" value="50" />
		<property name="statementsCachedPerConnection" value="30" />
		<property name="releaseHelperThreads" value="3" />
	</bean>
	<bean id="dataSource" class="org.springframework.jdbc.datasource.LazyConnectionDataSourceProxy">
		<property name="targetDataSource">
			<ref local="mainDataSource" />
		</property>
	</bean>
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9iDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
		<property name="mappingLocations">
			<list>
				<value>classpath:jbpm.execution.hbm.xml</value>
				<value>classpath:jbpm.history.hbm.xml</value>

				<value>classpath:jbpm.repository.hbm.xml</value>
				<value>classpath:jbpm.task.hbm.xml</value>
			</list>
		</property>
		<property name="annotatedClasses">
			<list>
				<value>com.fish119.jssh.pojo.Test</value>
			</list>
		</property>
	</bean>

	<!-- 事务配置开始 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	<!--事务配置-->
	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager">
			<ref bean="transactionManager" />
		</property>
		<!-- 配置事务属性 -->
		<property name="transactionAttributes">
			<props>
				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
				<prop key="delete*">PROPAGATION_REQUIRED</prop>
				<prop key="insert*">PROPAGATION_REQUIRED,-Exception</prop>
				<prop key="add*">PROPAGATION_REQUIRED,-Exception</prop>
				<prop key="update*">PROPAGATION_REQUIRED,-Exception</prop>

				<prop key="Test*">PROPAGATION_REQUIRED,-Exception</prop>
				<prop key="*Test">PROPAGATION_REQUIRED,-Exception</prop>
			</props>
		</property>
	</bean>
	<bean id="autoproxy" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<list>
				<value>*Service</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>
	<!-- 事务配置结束 -->
	<bean id="testDAO" class="com.fish119.jssh.dao.TestDAO" autowire="byType">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>
</beans>

第四步：配置Struts2（使用了convention plugin）

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<constant name="struts.objectFactory" value="spring" />
	<!--
		<constant name="struts.objectFactory.spring.autoWire" value="type"/>
	-->

	<constant name="struts.devMode" value="true" />
	<constant name="struts.convention.classes.reload" value="true" />


	<!-- 结果资源所在路径 -->
	<constant name="struts.convention.result.path" value="/" />
	<!-- 默认action所在的包 -->
	<constant name="struts.convention.default.parent.package"
		value="myPackage" />
	<!-- 不被convention组件扫描的包  -->
	<!-- <constant name="struts.convention.exclude.packages" value=""/>  -->

	<package name="myPackage" extends="json-default">
	
		<global-results>
			<result name="exception">/error.jsp</result>
			<result name="error">/error.jsp</result>
			<result name="none">/error.jsp</result>
			<result name="login">/login.jsp</result>
		</global-results>

		<global-exception-mappings>
			<exception-mapping result="exception" exception="java.lang.Exception">
			</exception-mapping>
		</global-exception-mappings>

	</package>
</struts>

第五步：测试

1、建立action类：IndexAction

public class IndexAction extends BaseAction{

	private static final long serialVersionUID = 1L;

	ProcessEngine processEngine;
	RepositoryService repositoryService;
	ExecutionService executionService;
	TaskService taskService;
	HistoryService historyService;
	IdentityService identityService;

	public ProcessEngine getProcessEngine(){
		return processEngine;
	}

	public void setProcessEngine(ProcessEngine processEngine){
		this.processEngine = processEngine;
	}

	public RepositoryService getRepositoryService(){
		return repositoryService;
	}

	public void setRepositoryService(RepositoryService repositoryService){
		this.repositoryService = repositoryService;
	}

	public ExecutionService getExecutionService(){
		return executionService;
	}

	public void setExecutionService(ExecutionService executionService){
		this.executionService = executionService;
	}

	public TaskService getTaskService(){
		return taskService;
	}

	public void setTaskService(TaskService taskService){
		this.taskService = taskService;
	}

	public HistoryService getHistoryService(){
		return historyService;
	}

	public void setHistoryService(HistoryService historyService){
		this.historyService = historyService;
	}

	public IdentityService getIdentityService(){
		return identityService;
	}

	public void setIdentityService(IdentityService identityService){
		this.identityService = identityService;
	}


	public String execute(){
			System.out.println("processEngine:" + this.getProcessEngine());
			System.out.println("repositoryService:"
					+ this.getRepositoryService());
			System.out
					.println("executionServcie:" + this.getExecutionService());
			System.out.println("taskService:" + this.getTaskService());
			System.out.println("historyService:" + this.getHistoryService());
		return SUCCESS;
	}
}

 2、启动tomcat，访问http://localhost:8080/ProjectName/index。控制台出现以下内容：

processEngine:org.jbpm.pvm.internal.processengine.SpringProcessEngine@2553861

repositoryService:org.jbpm.pvm.internal.repository.RepositoryServiceImpl@22b044e

executionServcie:org.jbpm.pvm.internal.svc.ExecutionServiceImpl@220d12e

taskService:org.jbpm.pvm.internal.svc.TaskServiceImpl@22d9289

historyService:org.jbpm.pvm.internal.svc.HistoryServiceImpl@2257b64

identityService:org.jbpm.pvm.internal.svc.IdentityServiceImpl@223f277

 3、可以进一步进行事务测试，建立自己的Service类，添加测试方法，可以看到事务已由Spring统一管理，这里就不提供代码了

附件：所需的jar包（使用了hibernate annotation和struts2的convention-plugin，可能有多余的包，没做清理）：
