💡 Hint

Common Mistakes

Using a specific method name instead of a wildcard.

Omitting the wildcard causes no methods to match.

The * wildcard matches any method name in the specified package.

💡 Hint

Common Mistakes

Specifying a return type limits matched methods.

Using a specific type misses other methods.

The * wildcard matches any return type, so all public methods are matched.

💡 Hint

Common Mistakes

Using '.' matches only one character, not any prefix.

Using '..' is for packages, not class names.

The * wildcard matches any package or class prefix before 'Controller'.

Spring Boot

💡 Hint

Common Mistakes

Using specific return types limits matches.

Using access modifiers restricts methods unnecessarily.

The first * matches any return type, and the second * matches any method name.

5fill in blank

hard

Fill all three blanks to match any public method in classes under service package with names starting with 'save'.

Spring Boot

execution([1] [2].service..[3]save*(..))

Drag options to blanks, or click blank then click option'

Apublic

Bcom.example

C*

Dprivate

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong access modifier restricts matches.

Incorrect package name causes no matches.

Missing wildcard before 'save' limits class matches.

public matches access modifier, com.example is the base package, and * matches any class name prefix before 'save'.
