activiti配置开发

1     通过eclipse 建立maven项目  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">
<modelVersion>4.0.0</modelVersion>
<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>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring</artifactId>
<version>5.21.0</version>
</dependency>

<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>2.4.3</version>
</dependency>


<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.6</version>
</dependency>


<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
<version>1.7.6</version>
</dependency>


<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>


<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency>

</dependencies>
</project>

其中junit版本为4.12 

在resources下添加activiti.cfg.xml 文件，用来配置数据库的链接

文件内容如下：

<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  创建流程图

 src/main/java目录下创建一个diagrams，在该文件下建立 Activiti Diagram流程图，流程图如下：

id为  myProcessId    name 为   Myprocess

3  穿件数据库，表与写入数据  

  创建测试类，测试方法如下：

    

@Test //
public void ctables(){

//表不存在的话创建表
ProcessEngine processEngine = ProcessEngineConfiguration
.createProcessEngineConfigurationFromResource("activiti.cfg.xml")
.buildProcessEngine();

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

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

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


}

 

 运行后如果没有创建表 则数据库中创建activiti所需要的表

 创建流程后输出的结果为

2501
请假程序

表中数据如下：

SELECT * FROM act_re_deployment      部署对象表

SELECT *    FROM act_ge_bytearray      资源文件表

 SELECT *   FROM act_re_procdef          流程定义表
