activiti基础--0------------------------------生成23张表

1.工作流activiti.cfg.xml配置文件

<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">
        <!-- 连接数据库的配置 -->
        <property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf8"></property>
        <property name="jdbcUsername" value="root"></property>
        <property name="jdbcPassword" value="123456"></property>
        <!-- 没有表创建表 -->
        <property name="databaseSchemaUpdate" value="true"></property>
    </bean>

</beans>

2.生成工作流23张表（两种方式）

package Junit;

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

public class TestActiviti {

    /**
     * 1.使用代码创建工作流需要的23张表
     * 2.流程引擎ProcessEngine对象（所有操作都离不开引擎对象）
     */
    
    @Test
    public void createTable () {
        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
        //连接数据库的配置
        processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8");
        processEngineConfiguration.setJdbcUsername("root");
        processEngineConfiguration.setJdbcPassword("123456");
        //public static final java.lang.String DB_SCHEMA_UPDATE_FALSE = "false";不能自动创建表，需要表存在
        //public static final java.lang.String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";先删除表在创建表
        //public static final java.lang.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 );
    }
    
    /**
     * 使用配置文件创建工作流需要的23张表
     */
    
    @Test
    public void createTable2 () {
        ProcessEngineConfiguration processEngineConfiguration = 
                ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        
        //工作流的核心对象，processEngine对象
        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
        
        ProcessEngine processEngine2 = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml").buildProcessEngine();
        
        System.out.println("processEngine2: " + processEngine2 );
        
    }
}
