This article mainly explains "how to use web filter to increase solr background login authentication", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "how to use web filter to increase solr background login authentication" bar!

Solr backend comes with no login function, and the default access address is: http://localhost:8983/solr/#/( built-in jetty operation).

To add a login authentication method to the sorl background:

1. Login authentication using web server (e.g. jetty, tomcat)

The advantage of this approach is that you don't need to write additional code, you just need to configure the corresponding web server.

2. Use web filter to filter address verification

This approach is more flexible, but the disadvantage is that it requires a bit of code development.

This article introduces the second method:
