Dynamic agents implemented by JDK and CGLB respectively

It programmer development Essentials-all kinds of resources download list, history of the most IT resources, personal collection summary.

Spring is based on the choice of JDK or cglib:

(1) When the bean implements the interface, Spring uses the JDK's dynamic proxy (2) when the bean does not implement the interface, spring using CGLIB is the implementation

Purpose of the dynamic agent:

You can usually do permission interception, system monitoring, etc.

dynamic Proxy implemented by JDK:

Personservice.java interface

Personservicebean.java implementation classes that require proxies

Dynamic proxy classes implemented by JDK: Jdkproxyfactory.java

Test class Aopproxytest.java:

Post-Execution output:

Dynamic agents implemented by Cglib:

Animalservicebean.java class requiring proxy, no interface implemented

Dynamic proxy class implemented by Cglib: Cglibproxyfactory.java

Test class Aopproxytest.java:

Output Result:
