@EnableTransactionManagement proxyTargetClass not control by spring.aop.proxyTargetClass

[Dreampie]

if use @Transactional,and set spring.aop.proxyTargetClass=false, this class also create by cglib not jdk proxy,you must config @EnableTransactionManagement(proxyTargetClass=false) to use jdk proxy with @Transactional

@Service
public class DemoServiceImpl implements DemoService {

    @Transactional
    public void test() {
        System.out.println("Test");
    }
}

And @EnableTransactionManagement proxyTargetClass default value is false, why spring boot change to true?

This was changed in 1.4 (see #5423). We've generally found cglib proxies less likely to cause unexpected cast exceptions.

Sorry, I misunderstood your initial comment. You're saying you add spring.aop.proxyTargetClass=false to application.properties but we ignore that and use cglib regardless?

yes，@snicoll know this question，https://github.com/Dreampie/spring-boot-demo

the spring.aop.proxy-target-class is only used to toggle the configuration in AopAutoConfiguration for other proxy creation it is being ignored, like for @EnableTransactionManagement and the configuration of the PersistenceExceptionTranslationPostProcessor.

I noticed this during introducing Spring Boot into a project which used quite a lot of final classes (or classes with final methods). I ran into it in those areas but maybe there are a few more (like JMX for instance).
