application.yml

server:
  port: 8080
  servlet:
    context-path: /demo
# 若要访问端点信息，需要配置用户名和密码
spring:
  security:
    user:
      name: xkcoding
      password: 123456
management:
  # 端点信息接口使用的端口，为了和主系统接口使用的端口进行分离
  server:
    port: 8090
    servlet:
      context-path: /sys
  # 端点健康情况，默认值"never"，设置为"always"可以显示硬盘使用情况和线程情况
  endpoint:
    health:
      show-details: always
  # 设置端点暴露的哪些内容，默认["health","info"]，设置"*"代表暴露所有可访问的端点
  endpoints:
    web:
      exposure:
        include: '*'

端点暴露地址

将项目运行起来之后，会在控制台里查看所有可以访问的端口信息

  1. 打开浏览器，访问：http://localhost:8090/sys/actuator/mappings ，输入用户名(xkcoding)密码(123456)即可看到所有的mapping信息
  2. 访问：http://localhost:8090/sys/actuator/beans ，输入用户名(xkcoding)密码(123456)即可看到所有 Spring 管理的Bean
  3. 其余可访问的路径，参见文档
