The AspectJ Pointcut syntax is very detailed

Classified pointcuts follow a specific syntax to capture the usable join points of each kind. Main types:
Method execution: execution(MethodSignature)
Method call: call(MethodSignature)
Constructor execution: execution(ConstructorSignature)
Constructor call: call(ConstructorSignature)
Class initialization: staticinitialization(TypeSignature)
Property read operation: get(FieldSignature)
Attribute write operation: set(FieldSignature)
Exception handling execution: handler(TypeSignature)
Object initialization: initialization(ConstructorSignature)
Object pre initialization: preinitialization(ConstructorSignature)

Advice execution: adviceexecution()
The pointcut indicator is used to indicate the purpose of the pointcut expression. At present, there is only one connection point, the execution method, in Spring AOP. The AspectJ pointcut indicators supported by Spring AOP are as follows:
Execution: the connection point used to match the execution of the method;
Within: used to match the method execution within the specified type;
this: the execution method used to match the current AOP proxy object type; Note the type matching of AOP proxy object, which may include the introduction of interface type matching;
Target: the execution method used to match the current target object type; Note that the type matching of the target object does not include the type matching of the imported interface;
args: used to match the currently executed method. The parameter passed in is the execution method of the specified type;
@Within: used to match the methods within the specified annotation type;
@Target: the execution method used to match the current target object type, where the target object holds the specified annotation;
@args: used to match the execution of the currently executed method. The parameters passed in hold the specified annotation;
@Annotation: used to match the method with the specified annotation held by the current execution method;
Bean: extended by Spring AOP, AspectJ has no execution method for the indicator to match the bean object with a specific name;
reference pointcut: refers to referencing other named pointcuts. Only @ ApectJ style is supported, but Schema style is not.

To learn about the following wildcards for AspectJ type matching:
: matches any number of characters;
...: matches the repetition of any number of characters, such as matching any number of subpackages in the type pattern; Match any number of parameters in the method parameter pattern.
+: matches the subtype of the specified type; Can only be placed after the type mode as a suffix.
java.lang.String matches the String type;
java..String matches the string type under any "first level sub package" under the java package;
Such as matching Java Lang. string, but does not match Java lang.ss. String
Java... * matches any type under java package and any sub package;
Such as matching Java lang.String,java.lang.annotation.Annotation
java.lang.*ing matches any Java Type ending in ing under Lang package;
java.lang.Number + matches Java Self type of any Number under Lang package;
Such as matching Java Lang. integer, which also matches Java math. BigInteger

For example:

Execution of any public method:
execution(public * (...))
Execution of any method starting with "set":
execution( set*(...))
Execution of any method of AccountService interface:
execution(* com.xyz.service.AccountService.(...))
Execution of any method defined in the service package:
execution( com.xyz.service..(...))
Execution of any method of any class defined in the service package and all sub packages:
execution(* com.xyz.service....(...))
Execution of any method of JoinPointObjP2 class defined in pointcutexp package and all sub packages:
execution(* com.test.spring.aop.pointcutexp...JoinPointObjP2.*(...))")
*>The closest (...) is the method name (...)) is the class name or interface name, such as JoinPointObjP2 (…))

Any class in the pointcutexp package
within(com.test.spring.aop.pointcutexp.)
pointcutexp package and any class in all sub packages
within(com.test.spring.aop.pointcutexp...)
Implements all classes of Intf interface. If Intf is not an interface, limit a single Intf class
this(com.test.spring.aop.pointcutexp.Intf)
***>When a class that implements an interface is AOP, the getBean method must cast as the interface type, not the type of this class

Any method of all classes with @ Transactional annotation
@within(org.springframework.transaction.annotation.Transactional)
@target(org.springframework.transaction.annotation.Transactional)
Any method with @ Transactional annotation
@annotation(org.springframework.transaction.annotation.Transactional)
***>@ within and @ target are annotations for classes, @ annotation is annotations for methods

Method with @ Transactional annotation for parameter
@args(org.springframework.transaction.annotation.Transactional)
The parameter is a method of String type (run is determined)

//@ Aspect can no longer decorate interfaces, but can only be classes
//aspectOf() and hasAspect() can no longer be used when accessing an aspect instance
//Instead, take the class of aspect as the parameter, and use org aspectj. Lang. aspects provides static methods aspectOf() and hasAspect()
@Aspect("perthis|pertarget|percflow|percflowbelow(Pointcut) | pertypewithin(TypePattern)")
//Defining the priority of aspect s requires the use of fully qualified names, which is very common in @ AspectJ and is also determined by the Java compiler

// When defining pointcut, you should still pay attention to the use of fully qualified names
// The method is just a placeholder, and the method body is empty except that it adopts the if() cut in method similar to conditional compilation
// If the method throws an exception, you should also add the throws declaration to the method prototype
// Remember to turn on the compiler option - g:vars and let the compiler reserve parameter names (this method is adopted for construction)
@Pointcut("execution(public * ajia.banking.domain.Account.*(float)) && this(account) && args(amount)")

// Or use the attribute of Annotation to establish the association between parameter name and pointcut
