环境为mac系统,win请适当进行变更

1.下载和谐jar包(一般放在idea目录下,如mac系统路径 -javaagent:/Applications/IntelliJ IDEA.app/Contents/bin/jetbrains-agent.jar)

链接:https://pan.baidu.com/s/1uUjyJKH9rhpwIlAdCpiI4g 密码:7yp8

2.编辑idea的bin中的idea.vmoptions文件

打开idea–>Help–>Edit Custom VM Options…
在idea.vmoptions文件最后添加
-javaagent:/Applications/IntelliJ IDEA.app/Contents/bin/jetbrains-agent.jar

3.重启idea(如果有输入激活码的窗口弹出,否则选择Help–>Refister打开注册窗口) 输入激活码

5.重启idea看到激活时间到2089年

JetCache是一个基于Java的缓存系统封装，提供统一的API和注解来简化缓存的使用。 JetCache提供了比SpringCache更加强大的注解，可以原生的支持TTL、两级缓存、分布式自动刷新，还提供了Cache接口用于手工缓存操作。 当前有四个实现，RedisCache、TairCache（此部分未在github开源）、CaffeineCache(in memory)和一个简易的LinkedHashMapCache(in memory)，要添加新的实现也是非常简单的。

全部特性:

通过统一的API访问Cache系统
通过注解实现声明式的方法缓存，支持TTL和两级缓存
通过注解创建并配置Cache实例
针对所有Cache实例和方法缓存的自动统计
Key的生成策略和Value的序列化策略是可以配置的
分布式缓存自动刷新，分布式锁 (2.2+)
异步Cache API (2.2+，使用Redis的lettuce客户端时)
Spring Boot支持

Spring Boot应用将自动使用logback作为应用日志框架，Spring Boot启动的时候，由org.springframework.boot.logging.Logging-Application-Listener根据情况初始化并使用。

日志级别
从低到高分为TRACE < DEBUG < INFO < WARN < ERROR < FATAL，如果设置为WARN，则低于WARN的信息都不会输出。

Spring Boot官方推荐优先使用带有-spring的文件名作为你的日志配置（如使用logback-spring.xml，而不是logback.xml），命名为logback-spring.xml的日志配置文件，spring boot可以为它添加一些spring boot特有的配置项（下面会提到）。
上面是默认的命名规则，并且放在src/main/resources下面即可。如果你即想完全掌控日志配置，但又不想用logback.xml作为Logback配置的名字，可以在application.properties配置文件里面通过logging.config属性指定自定义的名字：logging.config=classpath:logback.xml(潜台词:没有自定义就不用配置了)

学的东西越多,越感觉自己的盲区更多,懂得越少,这大概是为什么有些人懂得越多,却愈加小心翼翼,心怀忐忑.
成长所需的知识太多,什么都想学,但时间是有限的,只能自己去规划更适合自己的内容...
当学完java编程思想,spring源码解析,鸟哥的私房菜后
有深入理解java虚拟机,研磨设计模式,数据结构和算法,mybatis源码解析,spring高级编程等
之后还有java并发编程实战,kafka实战,redis实战,InnoDB详解,高性能mysql,elasticsearch权威指南,Netty权威指南...
再者计算机组成与设计,计算机网络,编译原理等
而代码整洁之道,重构改善既有代码的设计,Effective java将伴随你一生

曾经看过一个理论,知识就好像一个圈,圈内是已经掌握的,圈外是还没有掌握的,而学的越多,圈就越大,但同时接触的圈外世界也越大.
