springboot中动态切换log日志级别
1、pom.xml配置
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>2.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
2、application.yml配置
#管理端点
management:
#server:
# port: 7001
# address: 127.0.0.1
#endpoint:
# shutdown:
# enabled: true #优雅停机
endpoints:
web:
base-path: /actuator #默认路径也是/actuator
exposure:
#include: "*" 表示开放所有端点访问
include:
- info #默认开放,查看应用信息 ,获取的是application.yml中的info节点的信息
- health #默认开放,查看应用健康状态
- loggers #可查看和切换日志级别
- mappings # 查看controller层映射
- beans # 查看容器中的所有bean
- env #查看环境变量
- shutdown # 停机
3、 项目中记录日志的代码
import lombok.extern.slf4j.Slf4j; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.context.annotation.EnableAspectJAutoProxy; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @EnableAspectJAutoProxy(exposeProxy=true,proxyTargetClass=true) @SpringBootApplication @Slf4j public class LogDemoApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(LogDemoApplication.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(LogDemoApplication.class); } @RequestMapping("/") public String index(){ log.info("这是一条info级别日志"); log.debug("这是一条debug级别日志"); return "hello springboot!"; } }4、application.yml中日志级别的配置
server: port: 8082 servlet: context-path: / #管理端点 management: #server: # port: 7001 # address: 127.0.0.1 endpoint: shutdown: enabled: true endpoints: web: base-path: /actuator exposure: #include: "*" #loggers include: - info - health - loggers - mappings - beans - env - shutdown logging: level: root: INFO org.springframework.web: INFO org.springframework.jdbc: INFO com.tingcream: INFO #项目包日志级别 file: /log/logdemo/logdemo.log
启动springboot项目后, 访问 http://localhost:8082/ 发现只输出了一条info级别的日志。
curl -X GET http://192.168.0.14:8082/actuator/loggers/com.tingcream
发现com.tingcream 的日志level配置的是info,所以debug级别的日志才没有输出来
现在,我们使用curl 命令将com.tingcream包的日志level修改为debug
curl -X POST http://192.168.0.14:8082/actuator/loggers/com.tingcream -H "Content-type: application/json" -d "{\"configuredLevel\":\"DEBUG\"}"
再次请求首页,发现info和debug级别的日志都输出来了。。
附,常用的端点
http://localhost:8082/actuator/health #健康
http://localhost:8082/actuator/info #信息 获取的是application.yml中的info节点的信息,如info.app.name=xxx
http://localhost:8082/actuator/beans #spring容器中的bean
http://localhost:8082/actuator/env #环境变量
http://localhost:8082/actuator/metrics #指标
http://localhost:8082/actuator/mappings # controller层请求映射
http://localhost:8082/actuator/configprops # application.yml中的配置属性
优雅停机
curl -X POST http://localhost:8082/actuator/shutdown
