從Unauthorized 401錯誤學習Spring Boot的Actuator

 

以前用Spring Boot都是別人搭好的框架，而後本身在裏面寫就好了。對原理、細節上都怎麼涉及，畢竟需求都作不完。可是昨天一個訪問RESTful接口的401問題搞了我2個小時。網上找的不少用：

1 managements.security.enabled=false

而且添加一個actxxx包的方法對我也無論用，由於項目裏面已經配置了這個。可是我仍是遇到了401的這個問題。不死心繼續搜，而後加入了這個配置就行了：

1 security.ignored=/**

解決這個問題竟然花了我兩個小時，仍是處處去找，不懂Spring Boot框架的原理，好比安全方面的，除了問題兩眼一抹黑。

目標：弄清Spring Boot總體框架和框架中每一個小塊的基本知識。

Features

• Create stand-alone Spring applications

• Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)

• Provide opinionated 'starter' dependencies to simplify your build configuration

• Automatically configure Spring and 3rd party libraries whenever possible

• Provide production-ready features such as metrics, health checks and externalized configuration

• Absolutely no code generation and no requirement for XML configuration

 真的是打擾了，內容好像挺多的。

 

 第四部分：Spring Boot Actuator: 爲生產環境準備的特性

Actuator: 執行器，驅動器。當你把應用發佈到生產環境的時候，Spring Boot提供了一些額外的特性來幫助你監控和管理應用。你經過選擇HTTP endpoints或者JMX來管理和監控你的應用。

審計，健康和度量收集能夠自動地加入到應用中。
