I was trained to learn the basics of java, web and struts.

Later, I worked and became familiar with struts, ibatis, spring and db2 (database).

Later, the open source framework was upgraded, and so was jdk. Ajax began to heat up, and jquery began to heat up. Along the way, spring4, struts2, springmvc, hibernate, webservice, mina, xml, json, ajax, jquery (css and div programming I added later). Later, there were ligerui, jqueruiand so on.

There are many things I haven't listed, such as thread pools, such as timers, such as various communication protocols, such as distribution, such as containers, such as connection pooling. . . . . . .

During this period, I came into contact with java mode development and learned all kinds of encryption. I started developing small projects with new technologies, using activity as the process engine, and began to use mysql and oracle compulsorily.

The rise of the internet. Hadoop, storm and other technologies, redis and other cache databases.

. . . . . .

I'm still studying, although I'm a technical manager. But there are still many that have not been touched or practiced.

It's a long road. My classmates basically chose to leave. So be careful.
