eclipse创建activiti6 项目demo

1 新建maven 项目

2 修改 pom 文件，完整内容如下

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

3 在resources 文件夹下添加配置文件 activiti.cfg.xml，主要配置一个 processEngineConfiguration

<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/activiti?characterEncoding=utf8"/>
        <property name="jdbcUsername" value="root"/>
        <property name="jdbcPassword" value="root123"/>
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>
</beans>

4 配置log4j的配置文件 log4j.properties

log4j.rootLogger=DEBUG, ACT

log4j.appender.ACT=org.apache.log4j.ConsoleAppender
log4j.appender.ACT.layout=org.apache.log4j.PatternLayout
log4j.appender.ACT.layout.ConversionPattern= %d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n

5 添加一个类，App.java

package com.huitong.actdemo1;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;

/**
 * Hello world!
 *
 */
public class App
{
    public static void main( String[] args )
    {
        ProcessEngine pengine = ProcessEngines.getDefaultProcessEngine();

        RepositoryService repService = pengine.getRepositoryService();

        RuntimeService runService = pengine.getRuntimeService();

        TaskService taskService = pengine.getTaskService();

        pengine.close();
        System.out.println("結束了");

    }
}

6 运行后会发现数据库 activiti 中多了很多表，总共28张
