spring cloud微服务配置log4j2日志组件和zipkin进行服务链路追踪
在Spring Cloud中使用Log4j2替换默认的Logback日志组件,并进行服务链路追踪可以通过以下步骤实现:
- 添加依赖:
<!-- Log4j2 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
<!-- Zipkin -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>
- 配置Log4j2日志文件(
log4j2.xml
):
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
- 配置Zipkin相关属性(
application.properties
或application.yml
):
spring.zipkin.base-url=http://localhost:9411
spring.sleuth.sampler.probability=1.0 # 设置为1.0表示追踪所有请求,可以根据需要调整采样率
- 配置Zipkin Server:
@EnableZipkinServer
@SpringBootApplication
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}
- 在微服务中使用Spring Cloud Sleuth实现追踪:
@SpringBootApplication
public class YourServiceApplication {
public static void main(String[] args) {
SpringApplication.run(YourServiceApplication.class, args);
}
}
确保Zipkin Server正在运行,并且微服务在进行远程调用时会将追踪信息发送到Zipkin Server。这样就可以在Zipkin UI中查看服务间的调用链路和日志信息。
