HazelcastHealthIndicator是Spring Boot提供的一个健康指示器,用于检查Hazelcast分布式缓存的健康状态。通过配置和访问Spring Boot的HTTP端点,可以实现对Hazelcast的健康检查。
要使用HazelcastHealthIndicator配置和访问Spring Boot HTTP,可以按照以下步骤进行操作:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast</artifactId>
</dependency>
import com.hazelcast.core.HazelcastInstance;
import org.springframework.boot.actuate.health.AbstractHealthIndicator;
import org.springframework.boot.actuate.health.Health;
import org.springframework.stereotype.Component;
@Component
public class HazelcastHealthIndicator extends AbstractHealthIndicator {
private final HazelcastInstance hazelcastInstance;
public HazelcastHealthIndicator(HazelcastInstance hazelcastInstance) {
this.hazelcastInstance = hazelcastInstance;
}
@Override
protected void doHealthCheck(Health.Builder builder) throws Exception {
// 使用Hazelcast的API检查Hazelcast的健康状态
if (hazelcastInstance.getLifecycleService().isRunning()) {
builder.up();
} else {
builder.down();
}
}
}
/actuator/health
路径,并设置访问权限为所有用户:management.endpoints.web.base-path=/actuator
management.endpoints.web.exposure.include=health
management.endpoint.health.roles=ROLE_ACTUATOR
curl http://localhost:8080/actuator/health
响应示例:
{
"status": "UP",
"components": {
"hazelcast": {
"status": "UP",
"details": {
"clusterName": "my-cluster",
"clusterSize": 3,
"members": [
"192.168.0.1",
"192.168.0.2",
"192.168.0.3"
]
}
},
"diskSpace": {
"status": "UP",
"details": {
"total": 1024,
"free": 512
}
}
}
}
在上述示例中,可以看到Hazelcast的健康状态为"UP",并提供了一些详细信息,如集群名称、集群大小和成员列表。
