Spring Framework中的CGLIB是什么? [英] What is CGLIB in Spring Framework?

问题描述

什么是CGLIB?它与Spring有何关系?使用Spring Framework时，我们是否必须明确定义CGLIB的用法?

解决方案

参考Spring 代理目标类属性设置为true会使基于CGLIB的代理生效.

通过注释:

@Configuration
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class AppConfig {
   // ...
}

不需要将CGLIB添加到您的类路径中.从Spring 3.2开始，CGLIB被重新打包并包含在spring-core JAR中.

What is CGLIB and how it is related to Spring? Do we have to define usage of CGLIB explicitly when using Spring Framework?

解决方案

Ref Spring docs. What is CGLIB & how is it related to Spring?

CGLIB is a code generation library. Spring uses CGLIB, to generate proxies.

Spring AOP defaults to using standard JDK dynamic proxies for AOP proxies. This enables any interface (or set of interfaces) to be proxied.

Yes, you have to tell spring to use CGLIB based proxies explicitly.

Via xml:

<aop:aspectj-autoproxy proxy-target-class="true"/> proxy-target-class property is set to true will cause CGLIB-based proxying to be in effect.

Via Annotation:

@Configuration
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class AppConfig {
   // ...
}

There is no need to add CGLIB to your classpath. As of Spring 3.2, CGLIB is repackaged and included in the spring-core JAR.
