Apply the middleware to ServeMux to implement global logging. The complete sample code has been verified to run and is suitable for starting a small and medium-sized project.

Use the .equals() method to compare string content, because == only compare object references rather than content; 1. Use .equals() to compare string values equally; 2. Use .equalsIgnoreCase() to compare case ignoring; 3. Use .compareTo() to compare strings in dictionary order, returning 0, negative or positive numbers; 4. Use .compareToIgnoreCase() to compare case ignoring; 5. Use Objects.equals() or safe call method to process null strings to avoid null pointer exceptions. In short, you should avoid using == for string content comparisons unless it is explicitly necessary to check whether the object is in phase.
