springboot2.0 actuator端点监控
1. 概念
spring boot对应用提供了一系列的监控端点，可以查看应用的配置，监控信息等，非常方便。
| ID | Description | Enabled by default (Web项目) |
|---|---|---|
| auditevents | Exposes audit events information for the current application | NO |
| beans | Displays a complete list of all the Spring beans in your application. | NO |
| conditions | Shows the conditions that were evaluated on configuration and auto-configuration classes and the reasons why they did or did not match. | NO |
| configprops | Displays a collated list of all @ConfigurationProperties. | NO |
| env | Exposes properties from Spring’s ConfigurableEnvironment. | NO |
| flyway | Shows any Flyway database migrations that have been applied. | NO |
| health | Shows application health information. | YES |
| httptrace | Displays HTTP trace information (by default, the last 100 HTTP request-response exchanges). | NO |
| info | Displays arbitrary application info. | YES |
| loggers | Shows and modifies the configuration of loggers in the application. | NO |
| liquibase | Shows any Liquibase database migrations that have been applied. | NO |
| metrics | Shows ‘metrics’ information for the current application. | NO |
| mappings | Displays a collated list of all @RequestMapping paths. | NO |
| scheduledtasks | Displays the scheduled tasks in your application. | NO |
| sessions | Allows retrieval and deletion of user sessions from a Spring Session-backed session store. Not available when using Spring Session’s support for reactive web applications. | NO |
| shutdown | Lets the application be gracefully shutdown. | NO |
| threaddump | Performs a thread dump. | NO |
2. 使用端点监控actuator
2.1 引入端点监控actuator的starter
<dependency>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-actuatorartifactId>
dependency>2.2 配置端点监控actuator
端点监控的配置通过 management.* 配置文件来进行设置
- 端点监控的端口：默认和服务的端口(server.port)一样，可以通过management.server.port= xxxx 指定不同的端口
- 端点监控的服务名：如果没有单独设置端点监控的端口，端点监控的服务名和(server.servlet.context-path)一样；
如果单独设置了端点监控的端口，可以通过management.server.servlet.context-path= /xxxx 指定端点监控的服务名，不指定即为空 - 端点监控的前缀：management.endpoints.web.base-path= /actuator #端点的前缀，只对web服务有用
即端点监控的完整url为：management.server.servlet.context-path + management.endpoints.web.base-path + 具体的端点（例：/health） - 端点可以设置对外暴露不暴露，默认jmx全暴露，web只暴露info,health
- 可以通过management.endpoints.web.cors.*设置跨域访问规则
management.endpoints.jmx.expose=* # Endpoint IDs that should be exposed or '*' for all.
management.endpoints.jmx.exclude= # Endpoint IDs that should be excluded.
management.endpoints.web.expose=info,health # 定义暴露哪些端点，*为所有
management.endpoints.web.exclude= # Endpoint IDs that should be excluded.
management.endpoints.web.base-path=/actuator #端点监控的前缀，默认为/actuator， management.server.servlet.context-path + management.endpoints.web.base-path是端点的开始路径，
#各个端点功能都有一个enabled属性，可以用来控制开关
management.endpoint.env.enabled= # Whether to enable the env endpoint.
management.endpoint.health.enabled= # Whether to enable the health endpoint.
management.endpoint.info.enabled=true # Whether to enable the info endpoint.
# ENDPOINTS CORS CONFIGURATION (CorsEndpointProperties)
management.endpoints.web.cors.allow-credentials= # Whether credentials are supported. When not set, credentials are not supported.
management.endpoints.web.cors.allowed-headers= # Comma-separated list of headers to allow in a request. '*' allows all headers.
management.endpoints.web.cors.allowed-methods= # Comma-separated list of methods to allow. '*' allows all methods. When not set, defaults to GET.
management.endpoints.web.cors.allowed-origins= # Comma-separated list of origins to allow. '*' allows all origins. When not set, CORS support is disabled.
management.endpoints.web.cors.exposed-headers= # Comma-separated list of headers to include in a response.
management.endpoints.web.cors.max-age=1800 # How long the response from a pre-flight request can be cached by clients. If a duration suffix is not specified, seconds will be used.

比如/actuator/health端点可以看到应用的状态
4. 配合spring boot admin使用
如果配置了spring boot admin，可以可视化的看到这些开启的端点监控信息
spring boot admin的配置很简单，自行百度一下即可。
