使用jdk8学习JHipster教程

简介

JHipster是一个开发平台，可以快速生成、开发和部署现代Web应用程序和微服务架构，支持许多前端技术，包括Angular，React和Vue。

相信各位既然都已经看到了JHipster，应该也是对它有所了解了，在我看来这是一个很强大的全栈式脚手架。

1.安装JHipster

1.1 准备java8

我们首先需要jdk环境，关于java8的安装，可以查看我之前的文章——《Windows如何安装JDK8》。

1.2 准备node.js

我推荐使用nvm安装node.js，且官网要求，node.js版本必须是LTS版本，关于如何使用nvm安装node.js，可以查看我的这篇文章——《Windows安装nvm教程》。

成功安装nvm后请执行下面的指令，安装node.js的LTS版本，关于node.js的LTS版本具体有哪些，可以node.js的官方网站https://nodejs.org/en/download进行查阅。我们执行下面的命令安装v10.20.1。

nvm install 10.20.1

nvm use 10.20.1

node -v

npm -v

可以看到已经成功安装node 10.20.1。

1.3 安装JHipster

npm install -g generator-jhipster@6.10.5

JHipster版本6.10.5是最后一个支持Java8的版本了。

2.使用JHipster创建一个应用程序

官网教程可以参考《JHipster创建一个应用程序》。

2.1 找一个空文件夹

例如

mkdir D:\11\Documents\个人测试\app

cd D:\11\Documents\个人测试\app

2.2 执行jhipster

jhipster

2.3 后续结果如下

PS D:\11\Documents\个人测试\app> jhipster

3.使用JHipster

3.1 打开项目

使用idea打开D:\11\Documents\个人测试\app

3.2 设置项目

D:\11\Documents\个人测试\app\src\main\resources\config\application.yml

设置生效文件为application-prod.yml

spring:application:name: learnjhipsterprofiles:# The commented value for `active` can be replaced with valid Spring profiles to load.# Otherwise, it will be filled in by maven when building the JAR file# Either way, it can be overridden by `--spring.profiles.active` value passed in the commandline or `-Dspring.profiles.active` set in `JAVA_OPTS`active: prod

D:\11\Documents\个人测试\app\src\main\resources\config\application-prod.yml

设置你自己的postgresql数据库源

  datasource:type: com.zaxxer.hikari.HikariDataSourceurl: jdbc:postgresql://localhost:5432/learnjhipsterusername: learnjhipsterpassword:

设置你自己的redis数据库源

jhipster:http:cache: # Used by the CachingHttpHeadersFiltertimeToLiveInDays: 1461cache: # Cache configurationredis: # Redis configurationexpiration: 3600 # By default objects stay 1 hour (in seconds) in the cacheserver: redis://redis@localhost:6379/0cluster: false

若redis有密码，可以将auth认证这样写，第二个redis就是我的认证密码，使用0号数据库。

      server: redis://redis@localhost:6379/0

3.2 启动

进入D:\11\Documents\个人测试\app执行下列命令。

./mvnw
