spring boot actuator 簡單使用

spring boot admin + spring boot actuator + erueka 微服務監控

簡單的spring boot actuator 使用

POM

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <version>1.5.6.RELEASE</version>
        </dependency>      

application.yml 這裡開啟了SpringSecurity保護,一般應用上,我們使用form作為使用者登入,如果需要監控程式,那麼我們會需要一個與應用業務無關的賬戶.可以設定一個賬戶角色為admin,随便什麼的,可以使用httpbasic驗證

#開啟shutdown的安全驗證
management:
  security:
    enabled: true
    roles: USER
#  port: 8060
#  address: 127.0.0.1
  health:
    mail:
      enabled: false
#允許關閉請求
endpoints:
  shutdown:
    enabled: false      

httpbasic驗證,密碼必須是經過basic64編碼,這是編碼,不是加密

帶着請求頭去請求,傳回一大串資料
