前面咱們用代碼實現了生成25張activiti表,今天咱們用Activiti提供的activiti.cfg.xml配置文件來簡化實現前面的功能;html
官方文檔參考地址:http://activiti.org/userguide/index.html#configuration java
咱們先在src/test/resources下建立一個xml文件 名字是:activiti.cfg.xmlmysql
而後咱們從官方文檔貼下參考的xml代碼:spring

這裏的話,咱們要根據咱們的項目 修改jdbcUrl jdbcDriver jdbcUsername jdbcPassword 固然還有下面的配置咱們能夠去掉一些 後面會降到這些配置的用途;sql
修改完後的xml以下:async

接下來咱們就是要經過代碼來讀取配置文件,而後獲取工做流引擎實例:ide
代碼以下:測試

/**
* 使用xml配置 簡化
*/
@Test
public
void
testCreateTableWithXml(){
// 引擎配置
ProcessEngineConfiguration pec=ProcessEngineConfiguration.createProcessEngineConfigurationFromResource(
"activiti.cfg.xml"
);
// 獲取流程引擎對象
ProcessEngine processEngine=pec.buildProcessEngine();
}
|
而後咱們測試的時候 先把前面db_activiti數據下的表 所有刪除;ui
而後運行上面的測試類,咱們會發現 表自動生成了:spa
表依然是前面的25張表;
咱們會發現,使用xml配置會簡化不少東西。。
