Back-end of the most basic I think to grasp the following points:
1. Basic Java Syntax
2. Multithreading
3, the use of a variety of classic data structures, List, Set, map and its derived classes.
4, the classic spring MVC, have no say, now do Tomcat Web project is basically used it.
5, restful to understand
6, now the domestic industry, JSON with more, at least should master a JSON operation library: Jsonlib, Fastjson, etc., at present, the domestic industry fastjson used more. The current domestic industry preferred external interface form is Restful+json.
7, several database operation mode, native JDBC to understand. Several native JDBC-based frameworks should know at least one of the uses: Spring JdbcTemplate, Hibernate, Mybatis. Further, it is best to understand the usage of at least one database connection pool: Proxool, DBCP, C3P0, Druid, HIKARICP, at present, the domestic industry after two use more, because more efficient.
8, in addition to the Tomcat Web project knowledge. Advanced can also understand the current hot micro-service knowledge, this aspect of the current domestic industry with more frameworks: Dubbo, Zookeeper, Netty, Mycat and so on.
That's what I thought for the moment. In fact, more should write their own projects, such as writing a more complete personal blog, in the process, encounter problems try to search the current more popular technology to solve, so you will learn faster than light reading.
Talk about the front-end, in fact, the current domestic front-end is also relatively short (of course, excellent front end), the front-end treatment and prospects are also good.
What is the level of the Java backend that the front end needs to know?
