logback扩展功能

Demo 请参考 NutzWk

loglevel -- 动态修改NB项目日志等级

实现原理

• 客户端同步实例名称、进程ID到Redis，并通过TTL实现心跳机制

• 客户端订阅频道，当监听到命令则根据命令修改logback日志等级

配置文件(客户端与服务端一样)

#动态修改日志等级
logback.exts.loglevel.enabled=true
#心跳间隔(单位:秒)
logback.exts.loglevel.heartbeat=5

redis.host=127.0.0.1
redis.port=6379
redis.timeout=2000
redis.max_redir=10
redis.database=0
redis.maxTotal=100
#redis.password=test123
#redis集群模式设置 redis.mode=cluster
redis.mode=normal
#redis.nodes=

服务端发送命令

@Inject
private LoglevelService loglevelService;
    
LoglevelCommand loglevelCommand=new LoglevelCommand();
loglevelCommand.setAction("name");//action=name时 
loglevelCommand.setLevel("error");
loglevelCommand.setName("wk-nb-dubbo-sys");//action=name 时不为空
//loglevelCommand.setProcessId("1234");//action=processId 时不为空
loglevelService.changeLoglevel(loglevelCommand);

logfile -- 日志文件名带上进程ID

• 为了解决启动多个NB实例后，日志文件IO冲突问题

• logback.xml 示例，日志文件名为 sys-2019-01-21-1234.log

    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="org.nutz.boot.starter.logback.exts.logfile.LogfileTimeBasedRollingPolicy">
            <fileNamePattern>~/logs/sys-%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>15</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>[%-5level] %d{HH:mm:ss.SSS} %logger - %msg%n</pattern>
        </encoder>
    </appender>
