在Spring Cloud架构下使用Spring Boot的Logback日志处理方案,可以按照以下步骤进行:
1.引入logback依赖
在pom.xml文件中添加以下依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</dependency>
2.配置logback.xml文件
在src/main/resources目录下创建logback.xml文件,并添加以下配置:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<property name="LOG_HOME" value="/path/to/logs"/>
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_HOME}/app.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_HOME}/app.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<logger name="com.example" level="DEBUG">
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE" />
</logger>
<root level="INFO">
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE" />
</root>
</configuration>
其中,LOG_HOME为日志文件输出路径,可以根据需要进行修改。
3.logback.xml是Logback框架的配置文件,用于配置日志的输出格式、输出位置、日志级别等信息。
下面是logback.xml配置文件的主要内容:
3.1 配置输出位置
<property name="LOG_HOME" value="/path/to/logs"/>
3.2 配置输出格式
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
定义了日志输出的格式,包括时间、线程、日志级别、类名、日志信息等。
3.3 配置输出方式
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_HOME}/app.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_HOME}/app.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
定义了日志输出的方式,包括控制台输出和文件输出。其中,文件输出使用了滚动策略,即以时间为基准,每天生成一个
4.在应用程序中使用日志
在应用程序中使用日志,可以使用以下方式:文章来源:https://www.toymoban.com/news/detail-487393.html
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class MyClass {
private static final Logger logger = LoggerFactory.getLogger(MyClass.class);
public void myMethod() {
logger.debug("Debug log message");
logger.info("Info log message");
logger.warn("Warn log message");
logger.error("Error log message");
}
}
或者使用Lombok @Slf4j 注解 参考:https://blog.csdn.net/qq_20299791/article/details/89852458文章来源地址https://www.toymoban.com/news/detail-487393.html
5.logback.xml配置文件参考
<?xml version="1.0" encoding="UTF-8" ?>
<configuration scan="true" scanPeriod="3 seconds">
<property resource="application.yml"/>
<property name="LOG_PATH" value="/opt/log/"/>
<!-- <property name="LOG_PATH" value="/Users/changjiabo/opt/log/"/>-->
<springProperty scope="context" name="appName" source="spring.application.name" defaultValue="ho-cc"/>
<springProperty scope="context" name="env" source="spring.profiles.active"/>
<!-- 输出到控制台 -->
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">

</encoder>
</appender>
