概述
-
Spring-boot-starter-actuator 是用于監(jiān)控與管理的，只需引入依賴庫(kù)就能為應(yīng)用添加監(jiān)控端點(diǎn)
- 其中 /health 端點(diǎn)能夠全面你檢查應(yīng)用監(jiān)控狀態(tài)

- 比如訪問 /health 端點(diǎn)锁保，可以獲得如下的應(yīng)用健康信息
{"description":"Composite Discovery Client","status":"UP"}
常用端點(diǎn)
- 某些端點(diǎn)屬于敏感信息，需要關(guān)閉權(quán)限認(rèn)證才能查看 management.security.enabled=false
| URL |
描述 |
| /autoconfig |
該端點(diǎn)用于獲取應(yīng)用自動(dòng)化配置報(bào)告叛买，幫助我們方便的找到自動(dòng)化配置為什么沒有生效 |
| /beans |
描述上下文每個(gè) bean 的情況，包括 Java 類型已經(jīng)注入它的 bean蹋订，作用域等信息 |
| /enc |
應(yīng)用程序可用的所有環(huán)境屬性列表率挣，無論這些屬性是否用到，其中包括環(huán)境變量露戒、JVM 屬性椒功、命令行參數(shù)，以及配置文件 |
| /configprops |
獲取屬性如何進(jìn)行設(shè)置（注入或其它方式） |
| /mappings |
羅列出應(yīng)用程序的全部接口 |
| /metrics |
顯示應(yīng)用程序內(nèi)存情況智什、線程池动漾、JVM等信息 |
| /trace |
返回HTTP跟蹤信息，保留最近 100 條請(qǐng)求荠锭，包括請(qǐng)求的方法旱眯、路徑等詳細(xì)信息 |
| /info |
顯示應(yīng)用的信息 |
| /health |
顯示應(yīng)用的監(jiān)控信息 |
| /dump |
顯示程序運(yùn)行中的線程信息 |
| /shutdown |
通過該端點(diǎn)關(guān)閉應(yīng)用程序的遠(yuǎn)程操作，需要在配置文件里開啟 endpoints.shutdown.enabled=true |
