应该使用“静态最终记录器"吗?以大写形式声明? [英] Should a "static final Logger" be declared in UPPER-CASE?

问题描述

在 Java 中，静态最终变量是常量，并且约定它们应该是大写的.但是，我已经看到大多数人以小写形式声明记录器，这在 PMD 中被视为违规.

In Java, static final variables are constants and the convention is that they should be in upper-case. However, I have seen that most people declare loggers in lower-case which comes up as a violation in PMD.

例如:

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

只需搜索 google 或 SO 表示静态最终记录器"，你会亲眼看到这个.

Just search googleor SO for "static final logger" and you will see this for yourself.

我们应该使用 LOGGER 吗?

Should we be using LOGGER instead?

推荐答案

记录器引用不是常量，而是最终引用，不应大写.常量 VALUE 应为大写.

The logger reference is not a constant, but a final reference, and should NOT be in uppercase. A constant VALUE should be in uppercase.

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

private static final double MY_CONSTANT = 0.0;
