1、添加依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
2、通过实现HealthIndicator接口方式
@Component
public class MyHealthIndicator implements HealthIndicator {
@Override
public Health health() {
// 检查通过(方式一新建对象)
return new Health.Builder().withDetail("usercount", 10) //自定义监控内容
.withDetail("userstatus", "up").up().build();
// 检查失败(方式二静态方法)
//return Health.down().withDetail("status", errorCode)
// .withDetail("message", "服务故障").build();
}
}
3、通过继承AbstractHealthIndicator 方式
public class RedisHealthIndicator extends AbstractHealthIndicator {
private static final String VERSION = "version";
private static final String REDIS_VERSION = "redis_version";
private final RedisConnectionFactory redisConnectionFactory;
public RedisHealthIndicator(RedisConnectionFactory connectionFactory) {
Assert.notNull(connectionFactory, "ConnectionFactory must not be null");
this.redisConnectionFactory = connectionFactory;
}
@Override
protected void doHealthCheck(Health.Builder builder) throws Exception {
RedisConnection connection = RedisConnectionUtils
.getConnection(this.redisConnectionFactory);
try {
if (connection instanceof RedisClusterConnection) {
ClusterInfo clusterInfo = ((RedisClusterConnection) connection)
.clusterGetClusterInfo();
builder.up().withDetail("cluster_size", clusterInfo.getClusterSize())
.withDetail("slots_up", clusterInfo.getSlotsOk())
.withDetail("slots_fail", clusterInfo.getSlotsFail());
}
else {
Properties info = connection.info();
builder.up().withDetail(VERSION, info.getProperty(REDIS_VERSION));
}
}
finally {
RedisConnectionUtils.releaseConnection(connection,
this.redisConnectionFactory);
}
}
}
