上篇散仙写了一个很简单的入门级的Spring Boot的例子,没啥技术含量,不过,其实学任何东西只要找到第一个突破口,接下来的事情就好办了,人最怕什么? 我想莫过于干一件事情,没有下手的地方了,而当你一旦找到了这感觉,就可以很喜悦的顺藤摸瓜般的探索你强

最近数据分析的项目也即将告一段落了,中间也积累了很多知识,特此记录一下。其中用的最爽的Web组合开发就是Intellij IDEA + Maven + Spring Boot + Velocity + Boostrap + jQuery了,关于后端的数据分析和处理的Hadoop模块,会放在Hadoop分类的博客文章中记录。Spring Boot提供了一个强大的一键式Spring的集成开发环境,能够单独进行一个Spring应用的开发,其中:(1)集中式配置(application.properties)+注解,大大简化了开发流程(2)内嵌的Tomcat和Jetty容器,可直接打成jar包启动,无需提供Java war包以及繁琐的Web配置(3)提供了Spring各个插件的基于Maven的pom模板配置,开箱即用,便利无比。(4)可以在任何你想自动化配置的地方,实现可能(5)提供更多的企业级开发特性,如何系统监控,健康诊断,权限控制(6) 无冗余代码生成和XML强制配置(7)提供支持强大的Restfult风格的编码,非常简洁当然Spring Boot提供的功能,远远比上面的强大,散仙会在后续文章中,逐渐以实际工作中的项目为背景,穿插记录使用Spring Boot的心得体会。下面看一个入门级的例子:pom依赖:<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0"

开发 -> 测试 -> 部署,这是软件开发一般的简化流程,作为开发者我们总是希望能专注于开发,但往往会被一些开发之外的问题所折磨,比如繁多的spring依赖和不同的环境配置。带着这个问题,本文介绍运用springboot和docker开发和构建一个rest风格的web应用。
