activiti 6.0 和 ldap 集成

Question

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

我将activiti-ldap jar文件从here复制到

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

启动tomcat时出现以下错误

这是我的自定义配置文件

根据 Activi 文档，我是否还需要在一些 Pom.xml 中添加依赖项？请指教。

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

请查看活动用户指南中的“3.2. ProcessEngineConfiguration bean”部分。
