Spring Boot 2.3のApplication Availability

Spring Boot Features - 1.6. Application Availabilityを動かしただけのメモ。

build.gradle

plugins {
  id 'org.springframework.boot' version '2.3.0.RELEASE'
  id 'io.spring.dependency-management' version '1.0.9.RELEASE'
  id 'java'
}

sourceCompatibility = '11'
repositories {
  mavenCentral()
}
dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-actuator'
  implementation 'org.springframework.boot:spring-boot-starter-web'
  testImplementation('org.springframework.boot:spring-boot-starter-test') {
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
  }
}
test {
  useJUnitPlatform()
}

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Main {

  public static void main(String[] args) {
    SpringApplication.run(Main.class, args);
  }
}

application.properties

management.health.probes.enabled=true

これでhttp://localhost:8080/actuator/health/livenessとかhttp://localhost:8080/actuator/health/readinessにアクセスすると以下が返ってくる。

{"status":"UP"}
