添加配置文件 - activiti.cfg.xml

<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">
    <!--数据连接信息  -->
    <property name="jdbcUrl" value="jdbc:mysql:///activiti?createDatabaseIfNotExist=true" />
    <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUsername" value="root" />
    <property name="jdbcPassword" value="123456" />
    <!-- 自动建表 -->
    <property name="databaseSchemaUpdate" value="true" />
  </bean>

</beans>

测试
方式一： 无需配置

// 硬编码
	@Test
	public void testConnect() throws Exception {
		// 根据doc文档 ctrl+f ProcessEngineConfiguration 不用配置文件
		// 配置信息
		ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration
				.createStandaloneProcessEngineConfiguration();
		// jdbc 连接信息
		processEngineConfiguration.setJdbcUrl("jdbc:mysql:///activiti?createDatabaseIfNotExist=true");
		processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
		processEngineConfiguration.setJdbcUsername("root");
		processEngineConfiguration.setJdbcPassword("123456");
		// 自动创建表
		processEngineConfiguration.setDatabaseSchemaUpdate("true");
		// 服务核心对象 （一旦核心对象 它就会创建表结构）
		ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
		System.out.println(processEngine);
	}

方式二：加载配置文件 - activiti.cfg.xml

// 自定义配置文件
	// 
	@Test
	public void testConnect2() throws Exception {
		// 加载配置类的对象
		ProcessEngineConfiguration createProcessEngineConfigurationFromResource = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
		// 核心对象
		ProcessEngine buildProcessEngine = createProcessEngineConfigurationFromResource.buildProcessEngine();
	    System.out.println(buildProcessEngine);
	 }
