# Java 代码格式化
|
|
|
|
Doris 中 Java 部分代码的格式化工作通常有 IDE 来自动完成。这里仅列举通用格式规则，开发这需要根据格式规则，在不同 IDE 中设置对应的代码风格。
|
|
|
|
## Import Order
|
|
|
|
```
|
|
org.apache.doris
|
|
<blank line>
|
|
com
|
|
<blank line>
|
|
org
|
|
<blank line>
|
|
java
|
|
<blank line>
|
|
javax
|
|
<blank line>
|
|
```
|
|
|
|
* 禁止使用 `import *`
|
|
* 禁止使用 `import static`
|
|
|
|
## Checkstyle
|
|
|
|
现在的 `CI` 之中会有 `formatter-check` 进行代码格式化检测。
|
|
|
|
如果使用 `IDEA` 进行 Java 开发，请在设置中安装 `Checkstyle-IDEA` 插件。
|
|
|
|
在 `Tools->Checkstyle` 的 `Configuration File` 里点击 `Use a local Checkstyle file`，选择项目的 `fe/checkstyle.xml` 文件。
|
|
|
|
如果使用 VS Code 进行 Java 开发，请安装 `Checkstyle for Java` 插件，按照[文档](https://code.visualstudio.com/docs/java/java-linting)里的说明和动图进行配置。
