解析Java Checkstyle错误:Name 'logger'必须匹配pattern ' [A-Z][A-Z0-9]*(_[A-Z0-9]+)*$'

Using the Eclipse Checkstyle plugin I see this error:

使用Eclipse Checkstyle插件，我看到了这个错误:

Name 'logger' must match pattern '^[A-Z][A-Z0-9]*(_[A-Z0-9]+)*$'.

名字“记录器”必须匹配模式”^[a - z][A-Z0-9]*(_[A-Z0-9]+)*美元”。

I resolved this error by changing:

我通过改变来解决这个错误:

private static final Logger logger = Logger.getLogger(someClass.class);

私有静态最终记录器Logger = Logger. getlogger (someClass.class);

来

private static final Logger LOGGER = Logger.getLogger(someClass.class);

私有静态最终记录器Logger = Logger. getlogger (someClass.class);

Why is this a checkstyle warning?

为什么这是一个checkstyle警告?

2 个解决方案

#1

Because the field is marked final and static which implies that it's a constant and should be named with uppercase letters.

因为该字段标记为final和static，这意味着它是一个常量，应该用大写字母来命名。

From this link, you can see that the module ConstantName has the format ^[A-Z][A-Z0-9]*(_[A-Z0-9]+)*$ which is exactly the one your Checkstyle plugin has specified.

从这个链接,你可以看到模块ConstantName格式^[a - z][A-Z0-9]*(_[A-Z0-9]+)* $这正是你的Checkstyle插件指定。

#2

The documentation recommends using this configuration if you wish to keep logger as a valid option:

如果您希望将logger作为一个有效的选项，文档建议使用此配置:

<module name="ConstantName">
    <property name="format"
          value="^log(ger)?|[A-Z][A-Z0-9]*(_[A-Z0-9]+)*$"/>
</module>
