创建Activiti项目

 1.创建项目

 

 

 2.导入Activiti的jar包

项目上右击创建lib文件夹

 

将jar包复制进lib文件夹

 

3.导入数据库连接jar包

 

4.使用代码创建Activiti用来存放流程数据的23张表

 

package junit;import org.activiti.engine.ProcessEngine;import org.activiti.engine.ProcessEngineConfiguration;import org.junit.Test;public class TestActiviti {    /**     * 使用代码创建工作流需要的23张表     */    @Test    public void createTable(){        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();        //连接数据库配置        processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8");        processEngineConfiguration.setJdbcUsername("root");        processEngineConfiguration.setJdbcPassword("******");        /**          public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不能自动创建表，需要表存在          public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";//先删除表再创建表          public static final String DB_SCHEMA_UPDATE_TRUE = "true";//如果表不存在，自动创建表          */        processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);        //工作流的核心对象，ProcessEngine对象        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();        System.out.println("processEngine:"+ processEngine);    }}

 5.优化使用配置文件来创建工作流需要的23张表

 

activiti.cfg.xml

<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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">    <!--     ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();        //连接数据库配置        processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8");        processEngineConfiguration.setJdbcUsername("root");        processEngineConfiguration.setJdbcPassword("******");        /**          public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不能自动创建表，需要表存在          public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";//先删除表再创建表          public static final String DB_SCHEMA_UPDATE_TRUE = "true";//如果表不存在，自动创建表          */        processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);     -->    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">        <property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti?useUnicode=true&amp;characterEncoding=utf8"></property>        <property name="jdbcUsername" value="root"></property>        <property name="jdbcPassword" value="******"></property>        <!-- 没有表创建表 -->        <property name="databaseSchemaUpdate" value="true"></property>    </bean></beans>
