应该是“静态最终记录器”吗？在UPPER-CASE中宣布？ [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，惯例是它们应该是大写的。但是，我已经看到大多数人声称小写的记录器在 PMD 中出现违规行为。

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 为静态最终记录器，你会看到这个为你自己。

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，不应该是大写的。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;
