环境配置

项目环境:
JDK1.8
tomcat7
maven 3.5
开发工具:
IDEA
activiti7

创建项目

 	目标:创建一个maven项目,集成Activiti,并自动生成25张数据库表

  

准备工作

 	在数据库中运行:
	CREATE DATABASE activiti DEFAULT CHARACTER SET utf8;
	用于创建Activiti数据库
	在项目中会使用到BPMN图形,所以要先安装actiBPM插件,安装方法如下:
	在IDEA中实用快捷键Shift+Ctrl+Alt+S打开环境中心

  

新建一个maven项目

1.点击new Project创建一个新项目

2.选择maven项目创建

3.填写项目信息

4.设置maven信息

5.点击flsh完成项目创建,创建结构如下

6.补全项目中main文件夹下的java，resource等源文件夹
在IDEA中实用快捷键Shift+Ctrl+Alt+S打开环境中心,选择main包,右键new folder依次新建缺少的文件夹

7.创建完成后与对应文件源一一点击对应

8.在resources包下创建activiti.cfg.xml

代码如下:

 <?xml version="1.0" encoding="UTF-8"?>
< bean s xmlns="#34;
       xmlns:xsi="#34;
       xmlns:context="#34;
       xmlns:tx="#34;
       xsi:schemaLocation=" 
 
 #34;>
    <bean id="dataSource" class="org. apache .commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://192.168.0.114:3306/activiti"/>
        <property name="username" value="root"/>
        <property name="password" value="123456"/>
    </bean>
    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource"></property>
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>
</beans>

  

9.在resources包下创建log4j.properties

代码如下

 # Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache. axis .enterprise=FATAL, CONSOLE
​
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m
​
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=/Users/apple/学习/study/activity/activity_01/xis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m     

  

9.在test包下创建测试类,生成数据库表文件

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

/**
 * @author : YXC
 * @version : 1.0
 * @description :
 * @date : 2020/11/17 16:50
 */
public class ActivitiTest {
    @Test
    public  void testGenTable(){
        //1.创建ProcessEngineConfiguration对象
        ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        //2.创建ProcessEngine对象
        ProcessEngine processEngine = configuration.buildProcessEngine();
        System.out.println(processEngine);

    }

    @Test
    public void testGenTable2(){
        //使用下面这种方式生成表的条件
        //1.activiti配置文件名称必须为activiti.cfg.xml
        //2.bean的id必须为"processEngineConfiguration"
        ProcessEngine defaultProcessEngine = ProcessEngines.getDefaultProcessEngine();
        System.out.println(defaultProcessEngine);

    }
}

  

10.生成表结构如下
