集成log4j和lombok实现日志记录

一、引入相关依赖

        <!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-slf4j-impl -->
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-slf4j-impl</artifactId>
            <version>2.11.0</version>
        </dependency>
        <!-- lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.18</version>
            <scope>provided</scope>
        </dependency>

二、resources目录下创建配置文件log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="ON">
    <appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
        <RollingFile name="RollingFile" fileName="logs/app.log"
                     filePattern="logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz">
            <PatternLayout pattern="%d{yyyy.MM.dd 'at' HH:mm:ss z} %-5level %class{36} %L %M - %msg%xEx%n"/>
            <SizeBasedTriggeringPolicy size="5 MB" />
        </RollingFile>
    </appenders>
    <loggers>
        <root level="DEBUG">
            <appender-ref ref="Console"/>
            <appender-ref ref="RollingFile"/>
        </root>
    </loggers>
</configuration>

三、在类中使用

@Log4j2
public class BaseTest {
    private String host;
    private String env;
    private Properties properties;
    public BaseTest() {
        log.debug("读取配置文件");
        InputStream stream = this.getClass().getClassLoader().getResourceAsStream("env.properties");
        properties = new Properties();
        try {
            properties.load(stream);
        } catch (IOException e) {
            log.error("配置文件读取失败");
            e.printStackTrace();
        }
        String env = properties.getProperty("environment");
        String host = properties.getProperty("api.host");
        this.host = host;
        this.env = env;
    }
}
