Solve java. lang. IllegalStateException: BeanFactory not initialized or already closed,

Solve java. lang. IllegalStateException: BeanFactory not initialized or already closed,

I encountered this problem when I was running someone else's SSH project today.

This is because the project was originally using spring3.2, while my jdk is 1.8, spring3.2 is not compatible with jdk 1.8, so these problems are caused by upgrading the spring version to version 4 or above.
