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" 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" 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="identityService" factory-bean="processEngine" factory-method="getIdentityService"/><bean id="mainDataSource" 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="password" value="jbpm" /><property name="idleConnectionTestPeriod" value="60" /><property name="idleMaxAge" value="240" /><property name="maxConnectionsPerPartition" value="60" /><property name="minConnectionsPerPartition" value="20" /><property name="partitionCount" value="3" /><property name="acquireIncrement" value="10" /><property name="preparedStatementCacheSize" value="50" /><property name="statementsCachedPerConnection" value="30" /><property name="releaseHelperThreads" value="3" /></bean><bean id="dataSource" /></property></bean><bean id="sessionFactory" /></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.identity.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" ref="sessionFactory" /></bean><!--事务配置--><bean id="transactionInterceptor" /></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="save*">PROPAGATION_REQUIRED,-Exception</prop><prop key="*Save*">PROPAGATION_REQUIRED,-Exception</prop><prop key="exchange*">PROPAGATION_REQUIRED,-Exception</prop><prop key="remove*">PROPAGATION_REQUIRED,-Exception</prop><prop key="set*">PROPAGATION_REQUIRED,-Exception</prop><prop key="Test*">PROPAGATION_REQUIRED,-Exception</prop><prop key="*Test">PROPAGATION_REQUIRED,-Exception</prop></props></property></bean><bean id="autoproxy" 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@2553861repositoryService:org.jbpm.pvm.internal.repository.RepositoryServiceImpl@22b044eexecutionServcie:org.jbpm.pvm.internal.svc.ExecutionServiceImpl@220d12etaskService:org.jbpm.pvm.internal.svc.TaskServiceImpl@22d9289historyService:org.jbpm.pvm.internal.svc.HistoryServiceImpl@2257b64identityService: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）：
