1、导入Activiti所需Jar包

<!-- activiti 工作流 -->

<dependency> 

<groupId>org.activiti</groupId> 

       <artifactId>activiti-engine</artifactId> 

       <version>5.22.0</version> 

</dependency> 

 

<dependency> 

       <groupId>org.activiti</groupId> 

       <artifactId>activiti-spring</artifactId> 

       <version>5.22.0</version> 

</dependency>

2、创建spring-activiti.xml配置文件

用来注入activiti的6个service服务器，方便在controller中或service中注入

<?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"

      xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx"

      xmlns:aop="http://www.springframework.org/schema/aop"xmlns:util="http://www.springframework.org/schema/util"

      xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd

      http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd

      http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd

      http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsd

      http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">

 

<!-- 配置流程引擎配置信息对象 -->

<bean id="processEngineConfiguration"class="org.activiti.spring.SpringProcessEngineConfiguration"

p:dataSource-ref="dataSource"

p:transactionManager-ref="transactionManager"

p:databaseSchemaUpdate="true"

p:jobExecutorActivate="false"

p:databaseType="oracle"

             p:activityFontName="宋体"

             p:labelFontName="黑体"

             p:xmlEncoding="utf-8"/>

            

<!-- 配置流程引擎 -->

      <bean id="processEngine"class="org.activiti.spring.ProcessEngineFactoryBean"

         p:processEngineConfiguration-ref="processEngineConfiguration"/>

 

<!-- 配置六个服务Bean -->

       <beanid="repositoryService" factory-bean="processEngine"

factory-method="getRepositoryService" />

       <beanid="runtimeService" factory-bean="processEngine"

factory-method="getRuntimeService" />

       <beanid="taskService" factory-bean="processEngine"

factory-method="getTaskService" />

       <beanid="historyService" factory-bean="processEngine"

factory-method="getHistoryService" />

       <beanid="formService" factory-bean="processEngine"

factory-method="getFormService" />

       <beanid="identityService" factory-bean="processEngine"

                     factory-method="getIdentityService"/>

 

</beans>

在applicationContext.xml中引入spring-activiti.xml配置

<!-- 导入activiti配置 -->

<importresource="spring-activiti.xml"/>

3、创建数据库表

通过一个测试类自动生成所需要的activiti的数据库表

/**

 * ClassName:CreateDatabaseTest

 * @Description:创建数据库表

 * @author [email protected]

 * @date 2018年4月8日

 */

public class CreateDatabaseTest {

public static void main(String[] args) {

// 创建流程引擎配置信息对象

ProcessEngineConfiguration pec =ProcessEngineConfiguration

.createStandaloneProcessEngineConfiguration();

// 设置数据库的类型

pec.setDatabaseType("mysql");

// 设置创建数据库的方式

              //ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE(true): 如果没有数据库表就会创建数据库表，有的话就修改表结构.

//ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE(false): 不会创建数据库表

//ProcessEngineConfiguration.DB_SCHEMA_UPDATE_CREATE_DROP(create-drop): 先创建、再删除.

pec.setDatabaseSchemaUpdate("true");

// 设置数据库驱动

pec.setJdbcDriver("com.mysql.jdbc.Driver");

// 设置jdbcURL

pec.setJdbcUrl("jdbc:mysql://192.168.1.100:3306/**?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8");

// 设置用户名

pec.setJdbcUsername("***");

// 设置密码

pec.setJdbcPassword("***");

// 构建流程引擎对象

ProcessEngine pe = pec.buildProcessEngine(); // 调用访方法才会创建数据表

// 调用close方法时，才会删除

pe.close();

}

}
