SprintBoot-Vue

SpringBoot + 前端MVVM 基于Java的微服务全栈快速开发实践

Convenient & efficient and better performance for Java microservice full stack.

Commemorate the 1 anniversary of enter the profession.

Give beginner as a present.

———————By Mr.J

背景

如今Web开发领域,当有人提到Java时,总会让人觉得臃肿、古老而过时且开发效率没有某些动态语言高效,甚至在此之前还有人高喊“Java 已死!”,但是事实真是如此吗?其实如果你一直关注着Java,那你的感悟会更深,尽管它有很多的缺点和啰嗦,但不可否认,Java依然是工业界中最优秀的语言,而且它一直保持着与时俱进。本项目将使用SpringBoot + Vue2 + Webpack2 配合最简单CRUD的逻辑来展示一个基于Java的微服务全栈快速开发实践的Demo。

在某些时候,其开发效率已经并不比某些动态语言低。

为什么是SpringBoot

首先先来简单的介绍一下Spring,它是目前Java生态中最广为人知、流行的企业级Web框架。不像其他一些框架仅聚焦在某个领域,Spring框架通过其容器化组件式管理及开发,可提供或定制各式各样的功能来满足企业化需求。

那么相较于Spring,Spring Boot的目标是更加容易的创建Spring应用、建立自动化、最少人为干预的生产级配置,真正意义做到开箱即用,并且对于新用户及Spring平台的用户极易上手,快速开发。

下图主要展示了Spring Boot在Spring庞大的生态圈中的层级关系

spring_vue

SpringBoot的目标主要:

  • 为所有Spring开发提供一个从根本上更快,且随处可得的入门体验。

  • 开箱即用,但通过不采用默认设置可以快速摆脱这种方式。

  • 提供一系列大型项目常用的非功能性特征,比如:内嵌服务器,安全,指标,健康检测,外部化配置。

绝对没有代码生成,也不需要XML配置。

下面展示的是本项目的SpringBoot相关代码片段,你觉得简单么?

@RestController
@RequestMapping("/api/persons")
public class MainController {

    @RequestMapping(
            value = "/detail/{id}", 
            method = RequestMethod.GET, 
            produces = MediaType.APPLICATION_JSON_VALUE
            )
    public ResponseEntity<Persons> getUserDetail(@PathVariable Long id) {

        /*
        *    @api {GET} /api/persons/detail/:id  details info
        *    @apiName GetPersonDetails
        *    @apiGroup Info Manage
        *    @apiVersion 1.0.0
        *
        *    @apiExample {httpie} Example usage:
        *
        *        http GET http://127.0.0.1:8000/api/persons/detail/1
        *
        *    @apiSuccess {String} email
        *    @apiSuccess {String} id
        *    @apiSuccess {String} phone
        *    @apiSuccess {String} sex
        *    @apiSuccess {String} username
        *    @apiSuccess {String} zone
        */

        Persons user = personsRepository.findById(id);

        return new ResponseEntity<>(user, HttpStatus.OK);
    }

}

为什么是MVVM

那么在我继续之前,我也想和大家回顾一下Web开发的发展简史:

  • 第一阶段: 网页三剑客,生猛的通过原生javascript直接操作Dom树;

  • 第二阶段: JQuery诞生,配合前端MVC为代表的Backbone.js, 让我们可以优雅而简单的操作Dom树;

  • 第三阶段: 后端架构升级为MVC,前后端分工更清晰,前端工程化、ECMAScript规范开始崭露头角;

  • 第四阶段: 后端架构进入了微服务时代,前端架构不仅升级为MVVM,ES6更是成为目前事实上的标准;

在这里,我不想过于神化MVVM有多么的先进,JQuery为代表的MVC有多么的落后,但确实MVVM有着很多先进的特性:

  • 低开销

  • 易维护

  • 可重用

为什么选择Vue.js

Vue.js是MVVM设计模式中目前最火热的一个前端框架之一,除了性能表现优异之外,与类似React相比,更轻量级、更容易上手。

通过Vue中的“单文件组件”特性,更灵活的定义组件,不仅使代码结构更清晰,而且能与任何其他组件进行随意组合,更具复用性。

Webpack是什么

Webpack提供了一整套前端工程自动化的解决方案

Demo

一个简单的“上海人员信息查询系统”作为例子

demo-image

具备的功能(v0.1)

  • Spring Boot (后端)

    • 通过在Spring Boot中建立基于RestFul-API并使用@ RequestMapping实现一个基本的CRUD逻辑

    • 处理CORS(跨域资源共享)

    • 在Spring Boot中进行单元测试

    • 支持热加载

    • 增加api接口文档

    • 通过SpringBoot配合JPA来实现RestFul-API的分页

  • VueJS & webpack (前端)

    • 遵循ECMAScript 6 规范

    • 如何在vue中使用‘单文件组件’进行开发编码

    • 演示‘非父子组件’如何进行简单的通信以及‘父子组件’之间如何传递数据

    • 如何和后端进行数据交互

    • 如何在vue中优雅的引入第三方JS库

    • 格式化时间

    • 分页实现

    • 可复用组件

      • DbHeader.vue
      • DbFooter.vue (sticky footer)
      • DbFilterinput.vue
      • DbModal.vue
      • DbSidebar.vue
      • DbTable.vue

      得益于类似vue、react等MVVM模式,本项目的任何组件,只要您觉得合适,都可以复用在您的任何项目中,避免重复造轮子。

    • 如何通过webpack2配置来自动化构建前端环境(包括如何配置vue2、处理静态文件,构建不同环境等等)

本项目主要技术栈

  • Java 1.7
  • Spring Boot 1.5.x
  • Maven
  • sqlite (not recommend, only convenience example)
  • vueJS 2.x
  • webpack 2.x
  • element ui
  • axios

准备工作

  • 安装JDK1.7或更新的版本
  • 安装Node.js/NPM

  • 运行前端服务

      cd springboot_vue/frontend
    
      npm run dev
    

你也可以在生产环境中运行cd springboot_vue/frontend;npm run build进行编译并配合Nginx
