## 前言
`hsweb`是基于`java8`,`spring-boot`,`mybatis`开发.所以在开始使用`hsweb`的前,你至少应该掌握以下技术:`java`,`maven`.
最好掌握以下技术:`spring-boot`,`mybatis`. 如果对以上技术一无所知,请先去各大搜索引擎学习之. 

`hsweb`是一个模块化的项目,对各个功能进行了细分,这是为了更好的拓展性,但是在实际业务项目中,并不需要这样的细分,因此,强烈不建议自己直接将hsweb-framework clone下来在上面添加业务代码,正确的姿势是使用maven,根据自己的需求依赖hsweb的各个模块. 

hsweb 目前未提供前端支持,仅有一个[demo](https://github.com/hs-web/hsweb3-demo)可供参考.

本入门教程以一个最传统的单模块项目为例子. IDE为:`Intellij IDEA`

## 创建项目
1. 新建maven项目:

![新建项目](./img/create-project.gif "新建项目")

编辑`pom.xml`,然后`reimport`.如果对maven不够熟悉,maven的设置请使用默认设置,不要在settings.xml里自己添加私服.
否则可能出现依赖无法下载的问题.

        </pluginRepository>
    </pluginRepositories>
    
</project>
```

2. 在`resources`中创建`application.yml`配置
![application.yml](./img/create-application-yml.gif "application.yml")


```yaml
server:
  port: 8080

spring:
  aop:
      auto: true
  datasource:
     type: com.alibaba.druid.pool.DruidDataSource
     driver-class-name : com.mysql.jdbc.Driver
     url : jdbc:mysql://localhost:3306/myproject?useSSL=false&useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false
     username : root
     password : root

hsweb:
  app:
    name: my-project
    version: 1.0.0

logging:
  level:
     org.hswebframework.web: DEBUG
     org.hswebframework.web.cache: WARN
     org.apache.ibatis: DEBUG
     org.mybatis: DEBUG
```

3. 创建启动类
![MyProjectApplication.java](./img/create-application-java.gif "MyProjectApplication.java")

```java
package com.mycompany;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author zhouhao
 * @since 1.0
 */
@SpringBootApplication
public class MyProjectApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyProjectApplication.class,args);
    }
}
```

4. 创建数据库
```sql
    CREATE DATABASE IF NOT EXISTS myproject default charset utf8 COLLATE utf8_general_ci; 
```

5. 执行`MyProjectApplication.main`启动应用
![MyProjectApplication.java](./img/start-application.gif "MyProjectApplication.java")

打开浏览器访问 http://localhost:8080. 提示`Whitelabel Error Page`则说明服务启动成功.
因为现在还没有任何功能,所有提示错误信息.

到此,项目建立完成,和普通的spring-boot项目没有区别.


## 引入hsweb

以权限管理模块(`hsweb-system/hsweb-system-authorization`)为例.

在pom.xml中引入模块:
```xml
<!--权限控制-->
<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-authorization-basic</artifactId>
    <version>${hsweb.framework.version}</version>
</dependency>

<!--权限管理-->
<dependency>
    <groupId>org.hswebframework.web</groupId>
    <artifactId>hsweb-system-authorization-starter</artifactId>
    <version>${hsweb.framework.version}</version>
</dependency>
```

![import-authorization-module](./img/import-authorization-module.gif "import-authorization-module")
