Answer 1

In the class org.springframework.boot.autoconfigure.transaction.TransactionAutoConfiguration, there is such code(Spring Boot 1.5+):

    @Configuration
    @EnableTransactionManagement(proxyTargetClass = false)
    @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "false", matchIfMissing = false)
    public static class JdkDynamicAutoProxyConfiguration {

    }

    @Configuration
    @EnableTransactionManagement(proxyTargetClass = true)
    @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "true", matchIfMissing = true)
    public static class CglibAutoProxyConfiguration {

    }

The default is spring.aop.proxy-target-class=true, enabling CGLIB proxy by default. If you want to use JDK proxy, set spring.aop.proxy-target-class=false instead.
