1.1 建立專案

1.2 新增Jar包

1.3 更改配置檔案

1.3.1 連線資料庫

1.3.2 Spring檔案的配置

2 專案配置

applicationContext-dao.xml

<bean id="employeeDao" class="cn.itcast.ssh.dao.impl.EmployeeDaoImpl" parent="baseDao">
</bean>

<bean id="leaveBillDao" class="cn.itcast.ssh.dao.impl.LeaveBillDaoImpl" parent="baseDao"
 
>
</bean>

這裡說明一下：
parent=”baseDao”等同於

<bean id="baseDao" abstract="true">
<propertyname="sessionFactory"ref="sessionFactory"></property>
</bean>

applicationContext-service.xml

    <bean id="employeeService" class="cn.itcast.ssh.service.impl.EmployeeServiceImpl"
 
>
    <property name="employeeDao" ref="employeeDao"></property>    <!-- 員工-->
    </bean>
    <bean id="leaveBillService" class="cn.itcast.ssh.service.impl.LeaveBillServiceImpl">
    <property name="leaveBillDao" ref="leaveBillDao"></property> <!-- 請假單-->
 

    </bean>
    <bean id="workflowService" class="cn.itcast.ssh.service.impl.WorkflowServiceImpl">
    <property name="repositoryService" ref="repositoryService"></property>
    <property name="runtimeService" ref="runtimeService"></property>
    <property name="taskService" ref="taskService"></property>
    <property name="formService" ref="formService"></property>
    <property name="historyService" ref="historyService"></property>
    <property name="leaveBillDao" ref="leaveBillDao"></property>
    </bean>

applicationContext-action.xml

<bean id="loginAction" class="cn.itcast.ssh.web.action.LoginAction" scope="prototype">
<property name="employeeService" ref="employeeService"></property>
</bean>
<bean id="leaveBillAction" class="cn.itcast.ssh.web.action.LeaveBillAction" scope="prototype">
<property name="leaveBillService" ref="leaveBillService"></property>
</bean>
<bean id="workflowAction" class="cn.itcast.ssh.web.action.WorkflowAction" scope="prototype"><!--MVC預設是單例，改為多例-->
<property name="workflowService" ref="workflowService"></property>
<property name="leaveBillService" ref="leaveBillService"></property>
</bean>

activiti-context.xml，配置activiti表和事物以及service 不用建立流程引擎 直接引入就可以

<!-- spring負責建立流程引擎的配置檔案 -->
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<!-- 資料來源 -->
<property name="dataSource" ref="dataSource" />
<!-- 配置事務管理器，統一事務 -->
<property name="transactionManager" ref="transManager" />
<!-- 設定建表策略，如果沒有表，自動建立表 -->
<property name="databaseSchemaUpdate" value="true" />
</bean>
<!-- 建立流程引擎物件 -->
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>

<!-- 
相當於下面的程式碼
RepositoryServicie repositoryService = processEngine.getRepositoryService();
RuntimeServicie repositoryService = processEngine.getRuntimeServicie();
TaskServicie taskServicie = processEngine.getTaskServicie();
HistoryServicie historyServicie = processEngine.getHistoryServicie();
 -->
<!-- 由流程引擎物件，提供的方法，建立專案中使用的Activiti工作流的Service -->
<!--靜態注入 定義processEngine可以點出來service
-->
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />

struts的配置

<struts>
    <!-- 配置模式為開發模式，自動載入struts.xml和顯示錯誤提示資訊 -->
    <constant name="struts.devMode" value="true" />
    <!-- 設定頁面主題為簡單主題，去掉struts2開發提供的樣式 -->
    <constant name="struts.ui.theme" value="simple" />

    <package name="default" namespace="/" extends="struts-default">
