在本教程中，我们将看看Jhipster。

Jhihster是一个强大的开发工具，可以生成，创建和部署Spring引导和Angular JS或者更快地反应JS应用程序。

它将在任何时间为我们创建一个应用程序，它提供了许多开箱函数，如日志记录，指标，健康等。

我将展示我对Spring MVC Angular JS示例进行了证明的类似应用程序，并且我们将实现自动启动Spring 启动+角度/反应的更容易程度。

第1步：快速安装

• 从Oracle安装Java 8.
• 从Node.js安装Node.js(请使用LTS 64位版本，不支持非LTS版本)
• 从 Yarn 安装 Yarn
• 开放终端
• 如果我们想使用Jhipster Marketplace，请安装Yeoman： yarn global add yo
• 使用命令安装Jhipster： yarn global add generator-jhipster完成上述安装后，让我们创建示例项目。

第2步：项目设置

• 打开终端并执行以下命令
• Mkdir JhipsterhelloWorld.
• CD Jhipsterhelworld.
• Jhipster.

这将要求我们选择许多选项可供选择。

? Jan JHipster anonymously report usage statistics to improve the tool over time? No
? Which *type* of application would you like to create? Monolithic application (recommended for simple projects)
? What is the base name of your application? JhipsterHelloWorld
? What is your default Java package name? org.igi.theitroad
? Do you want to use the JHipster Registry to configure, monitor and scale your application? No
? Which *type* of authentication would you like to use? HTTP Session Authentication (stateful, default Spring Security mechanism)
? Which *type* of database would you like to use? SQL (H2, MySQL, MariaDB, PostgreSQL, Oracle, MSSQL)
? Which *production* database would you like to use? MySQL
? Which *development* database would you like to use? H2 with in-memory persistence
? Do you want to use the Spring cache abstraction? Yes, with the Ehcache implementation (local cache, for a single node)
? Do you want to use Hibernate 2nd level cache? No
? Would you like to use Maven or Gradle for building the backend? Maven
? Which other technologies would you like to use?
? Which *Framework* would you like to use for the client? Angular 6
? Would you like to enable *SASS* support using the LibSass stylesheet preprocessor? No
? Would you like to enable internationalization support? No
? Besides JUnit and Jest, which testing frameworks would you like to use?
? Would you like to install other generators from the JHipster Marketplace? No

完成上述步骤后，它将构建项目。

第3步：IDE中导入项目

我们需要将Eclipse作为Maven项目导入项目。
项目看起来如下。

后端

• Java代码始终包含在SRC/Main/Java文件夹中
• SRC/Main/Resources文件夹包含Java代码使用的静态资源。它还包含国际化文件和其他配置文件。
• 我们可以在SRC/TEST/JAVA文件夹中找到单元和集成测试

前端

• src/main/webapp是前手的根文件夹。
• app文件夹包含AngularJS模块
• I18N包含前端部分的国际化文件
• 前端的单元测试位于SRC/TEST/JAVASCRIPT/SPEC文件夹中

正如我们所看到的，Jhipster为我们创建了大量的软件包和文件。

第4步：运行NPM

在我们继续之前，我们需要启动Node.js服务器。
在IDE中运行以下命令。

CD JhipsterhelloWorld NPM开始

第5步：创建名为国家/地区的实体

实体是建筑物块的时髦应用程序。
实体实际上代表了商业对象，如用户，客户等。

创建实体实际上非常简单。
我们只需执行下面的命令并按照说明操作。

jhipster entity Country

执行上面的命令后，我们将得到以下选项

Executing jhipster:entity Country
Options:The entity Country is being created.Generating field #1? Do you want to add a field to your entity? Yes
? What is the name of your field? name
? What is the type of your field? String
? Do you want to add validation rules to your field? No================= Country =================
Fields
name (String)Generating field #2? Do you want to add a field to your entity? Yes
? What is the name of your field? population
? What is the type of your field? Long
? Do you want to add validation rules to your field? No================= Country =================
Fields
name (String)
population (Long)
Generating field #3
? Do you want to add a field to your entity? No
================= Country =================
Fields
name (String)
population (Long)
Generating relationships to other entities
<!-- /8691100/theitroad_S2S_Leaderboard_ROS_InContent -->

？
我们想与其他实体添加关系吗？
不

=================国家=================字段名称(字符串)人口(长)

？
我们是否想为业务逻辑使用单独的服务程序？
不，其余控制器应直接使用存储库？
你想要在你的实体上分页吗？
不

一切都配置了，生成实体......

第6步：构建Maven项目

以"清洁安装"为目标构建Maven项目。

第7步：运行项目

转到SRC/Main/Java/ORG/igi/ONITORAD和OPEN JHIPSERHOWLOWOLLLDAPL.JAVA

    }
 
    /**

     */
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(JhipsterHelloWorldApp.class);
        DefaultProfileUtil.addDefaultProfile(app);
        Environment env = app.run(args).getEnvironment();
        String protocol = "http";
        if (env.getProperty("server.ssl.key-store") != null) {
            protocol = "https";
        }
        String hostAddress = "localhost";
        try {
            hostAddress = InetAddress.getLocalHost().getHostAddress();
        } catch (Exception e) {
            log.warn("The host name could not be determined, using `localhost` as fallback");
        }
        log.info("\n----------------------------------------------------------\n\t" +

                "Profile(s): \t{}\n----------------------------------------------------------",
            env.getProperty("spring.application.name"),
            protocol,
            env.getProperty("server.port"),
            protocol,
            hostAddress,
            env.getProperty("server.port"),
            env.getActiveProfiles());
    }
}

如果我们注意到，此类是用@springBootApplication注释的，因此当我们运行此类时，它将被执行为Spring Boot应用程序。
运行java类以上时，我们将得到以下输出：
