所以对我来说,我试图记录执行时间,我创建了一个名为 ExecutionTime 的 pojo,其中包含名称、方法、类、持续时间。
然后我能够创建它:
ExecutionTime time = new ExecutionTime("Controller Hit", methodName, className, sw.getTotalTimeMillis());
对于日志记录,我使用了:
private final Logger logger = LoggerFactory.getLogger(this.getClass());
logger.info(append("metric", time), time.toString());
确保你有:
import static net.logstash.logback.marker.Markers.append;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
这将记录如下内容:
{
"ts":"2017-02-16T07:41:36.680-08:00",
"msg":"ExecutionTime [name=Controller Hit, method=setupSession, className=class com.xxx.services.controllers.SessionController, duration=3225]",
"logger":"com.xxx.services.metrics.ExecutionTimeLogger",
"level":"INFO",
"metric":{
"name":"Controller Hit",
"method":"setupSession",
"className":"class com.xxx.services.controllers.SessionController",
"duration":3225
}
}
可能是不同的设置,因为我使用 logback-spring.xml 将我的日志输出到 json:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml"/>
<property name="PROJECT_ID" value="my_service"/>
