activiti表的创建和简单示例

activiti23表的创建

代码语言：javascript复制

package junit;

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

public class TestActiviti {
    /**
     * 第一种方式：使用代码创建工作流需要的23张表
     */
    @Test
    public void createActivitiTable() {
        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
        processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/itcastactiviti?useUnicode=true&characterEncoding=utf8");
        processEngineConfiguration.setJdbcUsername("root");
        processEngineConfiguration.setJdbcPassword("123456");

        //DB_SCHEMA_UPDATE_TRUE 如果表不存在 自动创建表
        processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        //工作流核心对象 processEngine 
        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
        System.out.println("processEngine:" processEngine);
    }

    /**
     * 第二种方式：配置文件测试
     */
    @Test
    public void createActivitiCfgTable() {
        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti-cfg.xml");
        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
        System.out.println("processEngine:" processEngine);
    }
}

其中配置文件如下：

        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/itcastactiviti?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>

第三种方式： sql语句创建23张表
