Spring Learning (schema-based)---AOP (configuration-based AOP implementation)--Configuring Pointcuts Pointcut

Execution connection points for matching method execution

• Execution (Public * * (..))
• Execution (* set* (..))
• Execution (* com.xyz.service.accountservice.* (..))
• Execution (* com.xyz.service). (..))
• Execution (* Com.xyz.service ... (..))
• Within (com.xyz.service.*) (only in Spring AOP)
• Within (Com.xyz.service. *) (only in Spring AOP)
• This (Com.xyz.service.AccountService) (only in Spring AOP)
• ....

For a few examples:

• Execution (Public * * (..)) When a pointcut is executed for all public methods
• Execution (* set* (..)) The Pointcut is the method at which all set start is executed
• Execution (* com.xyz.service.accountservice.* (..)) When a pointcut is executed for all methods in the Accountservice class
• Execution (* com.xyz.service).            (..)) When a pointcut is executed for all methods under the Com.xyz.service package
• Execution (* Com.xyz.service ...            (..)) When a pointcut is executed for all methods under the Com.xyz.service package and its child packages

• Within (com.xyz.service.*) (only in Spring AOP)
• Within (Com.xyz.service. *) (only in Spring AOP) within used to match execution methods within the development type
• This (Com.xyz.service.AccountService) (only in Spring AOP) This is used to match the execution method of the current AOP proxy object type

Other

• Target (Com.xyz.service.AccountService) (only in Spring AOP) target is used to match the execution method of the current target object type
• Args (java.io.Serializable) (only in Spring AOP) args is used to match the currently executing method of the passed parameter to the specified type of execution method

annotation-based matching

• @target (Org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
• @within (Org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
• @annotation (Org.springframework.transaction.annotation.Transactional) (only in Spring AOP)
• @args (com.xyz.security.Classified) (only in Spring AOP)

Realize:

<aop:config>          <aop:pointcut id= "businessservice" expression= "Execution (* com.aop.schema). (..))" >                    </aop:pointcut></aop:config>

Example:

Create a new two class

Package com.aop.schema;/** *  * Slice class * */public class Myaspect {}

Package com.aop.schema;/** *  * Business class * */public class Apsectbiz {}
