Activiti学习笔记:①入门

Maven引入activiti组件,spring,spring-activiti:

      <!-- 引入工作流引擎以及所需要的jar包 -->
      <dependency>

配置文件activiti.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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">

    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti" />
        <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUsername" value="root" />
        <property name="jdbcPassword" value="123456" />

        <property name="databaseSchemaUpdate" value="true" />

    </bean>

</beans>

执行配置文件,生成db表(先在数据库中新建activiti库)

import org.junit.Test;

public class HelloWorld {
 /**
     * 使用xml配置 生成db
     */
    @Test
    public void testCreateTableWithXml() {
        // 引擎配置
        ProcessEngineConfiguration pec = 
 ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        // 获取流程引擎对象
        ProcessEngine processEngine = pec.buildProcessEngine();
    }
}
