05-Activiti7数据库的初始化

一、创建项目

创建一个maven工程。

如下图： 项目结构图
引入依赖：

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <artifactId>activiti01</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>

    <repositories>
        <repository>
            <id>alfresco</id>
            <name>Activiti Releases</name>
            <url>https://artifacts.alfresco.com/nexus/content/repositories/activiti-releases/</url>

                <enabled>true</enabled>
            </releases>
        </repository>
    </repositories>

</project>

二、配置

引入日志文件；
配置 activiti.cfg.xml 文件
配置内容如下：

<?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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                        http://www.springframework.org/schema/contex http://www.springframework.org/schema/context/spring-context.xsd
                        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--数据源配置dbcp-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/activiti" />
        <property name="username" value="root" />
        <property name="password" value="123" />
    </bean>
    <!--activiti单独运行的ProcessEngine配置对象(processEngineConfiguration),使用单独启动方式
        默认情况下：bean的id=processEngineConfiguration
    -->

    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        <!--代表数据源-->
        <property name="dataSource" ref="dataSource"></property>


        <!-- <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
         <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti" />
         <property name="jdbcUsername" value="root" />
         <property name="jdbcPassword" value="root" />-->
        <!--代表是否生成表结构-->
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>
</beans>

三、单元测试

代码如下：

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;

/**
 * @author ly
 * @Date: 2019/1/14 11:34
 * @description
 */
public class ActivitiTest {
    @Test
    public void testGenTable(){
        //创建ProcessEngineConfiguration
        ProcessEngineConfiguration configuration = ProcessEngineConfiguration
                        .createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        //通过ProcessEngineConfiguration创建ProcessEngine，此时会创建数据库
        ProcessEngine processEngine =
                configuration.buildProcessEngine();
        System.out.println(processEngine);
    }
}

四、activiti7数据库生成

生成：25张工作流表 activiti7工作流表
