activiti 6.0 and ldap integration

Question

查看 activiti 用户文档 https://www.activiti.org/userguide/#chapter_ldap，

我将 activiti-ldap jar 文件从这里复制到

webapps/activiti-app/WEB-INF/lib/activiti-ldap-6.0.0.jar

启动雄猫时出现以下错误

这是我的自定义配置文件

根据 Activi 文档，我是否需要在某些 Pom 中添加依赖项.xml？请指教。

Answer 1

您尝试使用 spring 类PropertyPlaceholderConfigurer，而不是活动提供的本机 ProcessEngineConfiguration 类之一。

请查看"3.2.进程引擎配置 bean"，在活动用户指南中。
