activiti配置開發

1     通過eclipse 建立maven項目  pom.xml 文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>mvn-act</groupId>
<artifactId>mvn-act-afid</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>

<dependencies>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-engine</artifactId>
<version>5.21.0</version>
</dependency>

</dependency>

</dependencies>
</project>

 

其中junit版本為4.12 

 

在resources下添加activiti.cfg.xml 文件，用來配置數據庫的鏈接

 

文件內容如下：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">


<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
<property name="jdbcDriver" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/act?characterEncoding=utf8"/>
<property name="jdbcUsername" value="root"/>
<property name="jdbcPassword" value="123456"/>
<property name="databaseSchemaUpdate" value="true"/>
</bean>
</beans>

 

2  創建流程圖

 src/main/java目錄下創建一個diagrams，在該文件下建立 Activiti Diagram流程圖，流程圖如下：

 

 

id為  myProcessId    name 為   Myprocess

 

3  穿件數據庫，表與寫入數據  

  創建測試類，測試方法如下：

 

    

@Test //
public void ctables(){

//表不存在的話創建表
ProcessEngine processEngine = ProcessEngineConfiguration
.createProcessEngineConfigurationFromResource("activiti.cfg.xml")
.buildProcessEngine();

System.out.println("------processEngine:" + processEngine);

//創建流程
Deployment deployment = processEngine.getRepositoryService().createDeployment().name("請假程序")
.addClasspathResource("diagrams/MyProcess.bpmn").addClasspathResource("diagrams/MyProcess.png").deploy();

System.out.println(deployment.getId());
System.out.println(deployment.getName());


}

 

 運行后如果沒有創建表 則數據庫中創建activiti所需要的表

 創建流程后輸出的結果為

2501
請假程序

 

表中數據如下：

 

SELECT * FROM act_re_deployment      部署對象表

 

 

 

SELECT *    FROM act_ge_bytearray      資源文件表

 

 

 SELECT *   FROM act_re_procdef          流程定義表
