1.运行HSDB代码

java -classpath "%JAVA\_HOME%/lib/sa-jdi.jar" sun.jvm.hotspot.HSDB

2.attach到对应的java程序进程上

3.进入下面页面：

4.选择Class Browser进入加载类页面：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 1][]

5.点击“create .class for all classes”生成所有已加载的类，或者点击具体的类，导出指定的类：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2pvaG4xMzM3_size_16_color_FFFFFF_t_70 2][]

当然要是查看cglib产生的类，也可以参考我的另一篇文章：[https://blog.csdn.net/john1337/article/details/76439507][https_blog.csdn.net_john1337_article_details_76439507]
