# Spring Boot Application Programmatically Monitoring and Restating

## 使用對象
> 當專案使用Spring boot project建置時可以使用,例如Spring rest service

## 安裝方式
1. Adding the Actuator Dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter</artifactId>
</dependency>

2. Setting the application.properties

#Spring Boot Restart Endpoint
management.endpoint.restart.enabled=true
management.endpoints.web.exposure.include=restart,health
#=====(Option)=====
server.servlet.contextPath=/definedContextPath
# Show details of health endpoint
management.endpoint.health.show-details=always

## 測試

### Restart service
> curl -X POST http://localhost:{PORT}{CONTEXTPATH}/actuator/restart
