Tomcat service configures all requests across domains – common

Two steps, make Tomcat service configuration all requests across domains, you can be happy to put a variety of static resources, full stack development learning is a lot more convenient. A lot of resources are not easy to find, this time found, directly share with you.

Tomcat, whether local or server, can be configured to fully release all cross-domain requests.

1. Prepare the REQUIRED JAR package

Add the tomcat folder to the lib folder
