04.DevTools

DevTools

springboot全局配置文件 springCloud场景下使用

bootstrap.yaml
bootstrap.yml
bootstrap.properties

springboot配置文件单体应用场景下使用
application.yaml
application.yml

application.properties

application.yaml > application.yml > application.properties

路劲	说明
file：./config/	工程文件夹下的config目录。
file：/	工程文件夹目录，如果是maven项目那么和pom.xml是一个层级
classPath：/config/	工程 classPath文件夹下的config文件夹
classPath：/	工程classpath文件夹

05.Intercepter

拦截器

preHandle、postHandle与afterCompletion
preHandle

调用时间：Controller方法处理之前

执行顺序：链式Intercepter情况下，Intercepter按照声明的顺序一个接一个执行

若返回false，则中断执行，注意：不会进入afterCompletion


postHandle

调用前提：preHandle返回true

调用时间：Controller方法处理完之后，DispatcherServlet进行视图的渲染之前，也就是说在这个方法中你可以对ModelAndView进行操作

执行顺序：链式Intercepter情况下，Intercepter按照声明的顺序倒着执行。

备注：postHandle虽然post打头，但post、get方法都能处理
 

afterCompletion

调用前提：preHandle返回true

调用时间：DispatcherServlet进行视图的渲染之后

多用于清理资源

Actuator监控分成两类：原生端点和用户自定义扩展端点，原生的主要有：

路径	描述
/autoconfig	提供了一份自动配置报告，记录哪些自动配置条件通过了，哪些没通过
/beans	描述应用程序上下文里全部的Bean，以及它们的关系
/env	获取全部环境属性
/configprops	描述配置属性(包含默认值)如何注入Bean
/dump	获取线程活动的快照
/health	报告应用程序的健康指标，这些值由HealthIndicator的实现类提供
/info	获取应用程序的定制信息，这些信息由info打头的属性提供
/mappings	描述全部的URI路径，以及它们和控制器(包含Actuator端点)的映射关系
/metrics	报告各种应用程序度量信息，比如内存用量和HTTP请求计数
/shutdown	关闭应用程序，要求endpoints.shutdown.enabled设置为true
/trace	提供基本的HTTP请求跟踪信息(时间戳、HTTP头等)
