| # 关于日志 | ||
|
|
||
| ### 日志变量定义的问题： | ||
|
|
||
| 在Android中，日志用Log | ||
|
|
||
| 在Log4j中，很多人用logger，我估计是怕变量重复 | ||
|
|
||
| 在@Slf4j(lombok)中，用log | ||
|
|
||
| 看了一下，我决定还是用 `log` | ||
|
|
||
| ### 日志初始化的问题 | ||
|
|
||
| 目前日志初始化的方式有这样三种（我这里选用slf4j框架） | ||
| ```java | ||
| // 第一种，使用lombok插件 | ||
| @Slf4j | ||
|
|
||
| // 第二种 | ||
| protected final Logger log | ||
| = LoggerFactory.getLogger(this.getClass()); | ||
|
|
||
| // 第三种 | ||
| protected static final Logger log | ||
| = LoggerFactory.getLogger(LBaseWebLogAspect.class); | ||
| ``` | ||
|
|
||
| 为什么要讨论呢？ | ||
|
|
||
| 有这样两个方面的原因： | ||
|
|
||
| 一是，如果使用静态变量，那么在任何方法中，都可以使用（该类中的静态方法或是非静态方法），另外，静态变量也是相当比较安全的。 | ||
|
|
||
| 二是，第1，3种，日志打印的名字是 `LBaseWebLogAspect`,也就是定义变量的类名，这不利于我们查找日志。 | ||
|
|
||
|
|
||
| 最后，你是否有注意到我前面的 `protected`，是的，你继承该类后，如果你需要记录日志，那么，你就可以直接使用 `log`这个变量了。 |
