checkstyle是提高代码质量,检查代码规范的很好用的一款工具，本文简单介绍一下集成的步骤，并提供一份完整的checkstyle的代码规范格式文件，以及常见的格式问题的解决方法。
一，安装
打开idea的文件选项，选择设置，进入后选择插件，搜索checkstyle,安装，安装后重启idea。
二，格式文件
在项目的根目录下新建checkstyle.xml文件
<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
"-//Checkstyle//DTD Checkstyle Configuration 1.3//EN"
"https://checkstyle.org/dtds/configuration_1_3.dtd">
<!--
Checkstyle configuration that checks the Google coding conventions from Google Java Style
that can be found at https://google.github.io/styleguide/javaguide.html
Checkstyle is very configurable. Be sure to read the documentation at
http://checkstyle.org (or in your downloaded distribution).
To completely disable a check, just comment it out or delete it from the file.
To suppress certain violations please review suppression filters.

</module>三，应用检查
1，打开设置--》工具--》Checkstyle
2，新增一个配置文件，并勾上
3，运行检查
四，常见格式问题的解决方法
1，==两边加空格
2，注释后面加句号
3，参数后面加上nonull
4，@param前面空一行
5，if后面要空格
6，参数里逗号后有空格
