Nested functions
Functions can be nested. The output of one function can be the input of another function. The operand has an inheritable execution process.

Nested techniques are generally used in such a way as decode can be used for logical judgment statements if .... THEN ... else's function.

Iv. issues that may arise
If your project uses log4j instead of log4j2, then the problem comes and you also need to join Log4j-api-2.7.jar and Log4j-core-2.7.jar and configure Log4j2.xml (for the moment it's empty).
Otherwise, you will always report the following error, as for why, have not yet in-depth understanding.
