log4j2的注意事项

如果使用spring-boot,首先应该排除springboot中自带的logback日志,引入log4j2的日志

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

其次在编写的过程中,尽量使用log4j2-api中的接口(log4j2-core是log4j2-api的官方实现,性能比logback、log4j、jul都要高很多),而不是其他门面日志系统(log4j2自身也是门面模式); 同时,日志的message尽量不能相同,不然很难排查问题,失去了日志的原有功能点。

import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.LogManager;

...

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

log4j2.xml配置文件中,不允许显示行号。使用%c或者%c{36}或者%logger或者%logger{36},注意是小写的c,大写的C将使用堆栈快照获取日志的位置信息 官方文档显示的信息,显示日志调用的位置信息,同步logger将花费1.3到5倍的时间,异步logger将花费30到100倍的时间 https://logging.apache.org/log4j/2.x/manual/layouts.html#LocationInformation
