推荐答案

会话范围的上下文仅在使用 service() 方法调用 servlet 期间或执行 servlet 过滤器时才处于活动状态.不确定您如何设置 Activiti 作业，但它似乎不在会话上下文的活动期内.因此，如果您注入任何需要 @SessionScoped 的 bean，则注入将失败.

Session scoped contexts are only active during servlet calls with the service() method, or when executing a servlet filter. Not sure how you have your Activiti job setup, but it would appear not to be within the active period of a session context. As such, if you inject any beans that require @SessionScoped then the injection will fail.

解决方案是移除需要 @SessionScoped 的 bean 注入，或者修改 bean.

The solution would be to remove the bean injections that require @SessionScoped, or to modify the beans.
