spring-boot推送实时日志到前端页面显示

日志级别在生产环境中尤为重要，一般都是配置为error级别，如果我想看更多的日志呢？切换很麻烦，所以在spring-boot1.5.X以上的版本支持日志级别动态切换了。

首先引入依赖

	org.springframework.boot
	spring-boot-starter-actuator

在spring-boot配置文件中配置

#默认false 否则无法动态切换日志等级
management:
  security:
    enabled: false

具体实现是

POST请求 loggers/包名 带上参数{'configuredLevel' : 日志级别}即可切换日志级别

GET请求 loggers/包名 可以获取此包名的当前日志级别，也可不带包名，直接返回所有包的日志级别

下面给出上一篇博客增加动态切换日志级别的前端代码  具体样式请自行更换
