我正在使用spring boot使用log4j2.xml的以下配置来登录apache tomcat日志:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorInterval="60">
<Properties>
<Property name="logdir">${sys:catalina.base}/logs</Property>
<Property name="layout">%d [%t] %-5p %c- %m%n</Property>
</Properties>
<Appenders>
<Console name="CONSOLE" target="SYSTEM_OUT">
<PatternLayout pattern="${layout}"/>
</Console>
<RollingFile name="FILEAPPENDER"
fileName="${logdir}/doc-reader.log"
filePattern="${logdir}/doc-reader.%d{yyyy-MM-dd}.log.gz">
<PatternLayout pattern="${layout}"/>
<Policies>
<SizeBasedTriggeringPolicy size="1 KB" />
</Policies>
<DefaultRolloverStrategy max="4"/>
</RollingFile>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="FILEAPPENDER"/>
</Root>
<Logger name="com.mypackage"
level="info"
additivity="false">
<AppenderRef ref="FILEAPPENDER"/>
</Logger>
</Loggers>
</Configuration>
此配置能够在tomcat的logs /文件夹中创建日志和压缩日志。而且它还会写入系统生成的消息,例如:
2018-12-11 11:16:20,359 [http-nio-8089-exec-1] INFO org.springframework.web.servlet.DispatcherServlet- Completed initialization in 9 ms
但是当我尝试使用控制器进行日志记录时,它无法写入日志文件:
package com.mypackage.controller;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
/**

*/
@RestController
public class DevController {
private static final Logger LOGGER = LogManager.getLogger(DevController.class);
@RequestMapping(value = "/health")
public String getCurrentDateTime() {
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");
LocalDateTime now = LocalDateTime.now();
LOGGER.info("Info : number is " + dtf.format(now));
LOGGER.warn("Warning : number is " + dtf.format(now));
LOGGER.debug("Debug : number is " + dtf.format(now));
LOGGER.error("Error : number is " + dtf.format(now));
LOGGER.fatal("Fatal : number is " + dtf.format(now));
return(dtf.format(now));
}
}
我针对不同的Google搜索提出了各种解决方案,但均无济于事,因此考虑将其发布为问题。我在这里做什么错了?
我的项目结构是:
doc-reader > src > main > java > com.mypackage > controller > DevController
doc-reader > src > main > java > com.mypackage > startup > DRStartupCacheLoader
答案 0 :(得分:0)
如果使用的是maven或gradle构建工具,则可以使用依赖项:
https://mvnrepository.com/artifact/org.slf4j/slf4j-api
添加此内容后,您可以尝试吗?
私有静态最终Logger LOGGER = LoggerFactory.getLogger(DevController.class);
