The plugin supports specifying multiple class + method combinations in a Declarer

[hs1515810]

What would you like to be added?

Currently, in Declarer, only class and method can be specified separately. It is necessary to support specifying multiple class + method combinations in one Declarer.

Why is this needed?

In the scenario of dynamically specifying listening methods, multiple classes and methods that need to be listened may be read from the configuration file. It is necessary to make a unified designation of these classes and methods in one Declarer.
