2018年終總結
序
不知不覺一年又要過去了，又到了寫總結的時候了。vue
盤點
總體而言，今年技術層面稍微有點拓寬，跨入了外表看上去高大上的流式計算領域，打開了另一扇窗；而基於java的分佈式/微服務領域，今年變化比較大，spring cloud netflix的部分組件宣佈將要進入維護階段，而國內spring cloud alibaba組件逐漸活躍起來，目前看來處於PublicEvolving階段；而java自身也處在不斷進化中，今年發佈了java10及java11，明年java12也要來了，版本變化很是快。稍不留神就跟不上技術更迭了。java
今年不知道爲何沒有什麼想說的了，感受總體而言本身表現很是通常，有點老氣沉沉的感受，多是失去了年輕時候的激情，面對現實開始接受本身的平庸。mysql
展望
面對紛繁複雜的技術，以爲技術真是無止境，有時候以爲本身真的很忙，時間真的不夠用；可是面對生活，有時候又以爲人畢竟也是要生活的，是爲技術而生活，仍是爲生活而技術，是一個值得思考的問題。react
今年定的幾個目標基本也沒有實現，明年就再也不定具體的目標了，大的幾個方向就是深刻研究流式計算及系統架構，同時也但願本身腳踏實地的同時多仰望星空，多感覺人文的世界。nginx
