以上是activiti-app-6.0的代码，但是以代码的方式进行spring的配置，我想改为xml文件方式进行配置，希望有经验的同学帮忙改一下，我等下会上传代码，我找了一些参考的网站（https://my.oschina.net/521cy/blog/702864），对照上面的方式进行配置还是不行

你这段代码是自定义了Listener。跟osc的那篇博客关系不大。 你参考下这篇 web.xml中 Listener的使用

上面是项目代码，按快了没编辑就发了，项目里面有我对项目转配置的尝试(都注释了)，默认账号密码都是admin

楼主改成xml格式，是想把activiti的modeler集成进自己的项目吧，我最近也在做这个，最后发现可以不用修改这个配置，在web.xml配置自己需要的东西即可，如我的配置如下

<listener>
    <listener-class>org.activiti.app.servlet.WebConfigurer</listener-class>
  </listener>
  <servlet>
    <servlet-name>springServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springServlet</servlet-name>
    <url-pattern>/lab/*</url-pattern>
  </servlet-mapping>
