> > * parent:被继承的父项目的构件标识符
> > * artifactId:项目的全球唯一标识符
> > * groupId:项目的版本
> > * properties：定义属性
> > * resources：资源文件

			<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
			<groupId>org.projectlombok</groupId>
			<artifactId>lombok</artifactId>
			<optional>true</optional>

```

### 自定义一个 CommandLineRunner

### 自定义单元测试

`出现乱码问题`

由乱码可知为以ISO-8859-1读取UTF-8所导致

更改后通过

`@RequestMapping(value = "/",produces = "application/json;charset=UTF-8")`

`等待仔细研究`

* 使用powershell默认启动springboot项目正常,带JVM参数时启动失败,[Stack Overflow](https://stackoverflow.com/questions/6347985/cannot-run-maven-using-mvn-d-argument-within-microsoft-powershell-but-works)中有关于cmd运行命令正常而powershell报错的提问,由帖子得-D对powershell为有有特殊意义参数,
* 改为使用git命令行运行,运行成功

### 设置debug

配置文件中设置`debug=true`

* ` mvn clean package`

* `java -jar target/demo-0.0.1-SNAPSHOT.jar --serverport=9080 --debug`

* gitbash出现中文乱码

* `方块形式为以UTF-8读取并显示GBK编码,但是已另存文件为UTF-8编码,仍出现此错误,将bash配置改为GBK则显示正常`
