SpringBoot Actuator——生产环境必备的监控与健康检查
SpringBoot Actuator 提供了生产级的监控能力——健康检查、指标收集、线程 dump、环境信息等。部署到生产环境前一定要加上。一、引入依赖dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-actuator/artifactId/dependency二、配置management:endpoints:web:exposure:include:health,info,metricsendpoint:health:show-details:always启动后访问http://localhost:9090/actuator/health查看应用状态。三、自定义健康检查ComponentpublicclassRedisHealthIndicatorimplementsHealthIndicator{AutowiredprivateRedisTemplateString,ObjectredisTemplate;OverridepublicHealthhealth(){try{redisTemplate.opsForValue().get(health-check);returnHealth.up().withDetail(redis,可用).build();}catch(Exceptione){returnHealth.down().withDetail(redis,不可用).withDetail(error,e.getMessage()).build();}}}四、常用端点端点用途是否默认开启/health健康检查✅/info应用信息✅/metricsJVM 指标✅/env环境变量❌ 生产关闭/loggers动态修改日志级别❌/threaddump线程 dump❌ 觉得有用的话点赞 关注【张老师技术栈】吧
