preface

Questions about the technical people how to grow up, has been closely watched, because programmers career development soon, even the same starting point, after several years of work or study, quickly great gap, so technical people keep learning, improve themselves, to prop up constantly in waves, after also not be “die” on the beach.

Recently, after the disclosure of a friend, Alibaba also launched a limited number of “Java growth manual”, which records the knowledge point is very complete, after reading, I know that the gap is really more than a little bit!

The manual mainly stratified Java programmers according to years, clearly marked what route Java programmers should follow to improve themselves, which technical points need to learn.

0-1 year introduction:

  • Java foundation rework (object-oriented +Java superclass +Java reflection mechanism + exception handling + collections + generics + basic IO operations + multithreading + network programming + NEW JDK features)
  • Web programming (Servlet+MySQL database + Commodity Management system combat)
  • SSM from entry to mastery (Spring+SpringMVC+Mybatis+ commodity management system combat -SSM version)
  • SpringBoot quick start (SpringBoot+ Commodity management system based on SpringBoot actual combat)
  • Zero distance Internet project combat (Linux+Redis+ Double eleven Seconds kill combat system)

1-3 years senior engineer:

  • Concurrent programming advanced (concurrent tool class combat +CAS+ display lock resolution + thread pool internal mechanism + performance optimization)
  • Deep JVM profiling (understanding runtime data area + out-of-heap memory reading +JDK+ memory leak detection +Arthas+GC algorithm and garbage collector + classloading mechanism, etc.)
  • MySQL advanced in depth
  • Go deep into Tomcat (Threading model + Performance tuning)

3-5 years experience:

  • Database (tuning + transaction + lock + cluster + master/slave + cache, etc.)
  • Linux (command + production environment + log, etc.)
  • Middleware & Distributed (Dubbo +MQ/ Kafka, ElasticSearch, SpringCloud and other components)

5-7 year structure:

  • Open source framework (Spring5 source +SpringMVC source +Mybatis source)

  • Distributed architecture (Zk +RabbitMQ+RocketMQ+Kafka)

  • Efficient storage (Redis+mongoDB+MySQL high availability +Mycat+Sharing-Sphere)

  • Microservice architecture (RPC+SpringBoot+SpringCloud+Netflix+SpringCloudAlibaba+ Docker + K8S)
