consul注册 acl token 心跳 处理
已经验证 好使，心跳启动成功启动会有日志：Add Consul heartbeat for: xxxxxx

三个类放同意包下&在spring scanBasePackages 范围内

1.重写ConsulHeartbeatAutoConfiguration

package com.support.consul;import com.ecwid.consul.v1.ConsulClient;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.autoconfigure.AutoConfigureAfter;import org.springframework.boot.autoconfigure.AutoConfigureBefore;import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;import org.springframework.cloud.client.ConditionalOnDiscoveryEnabled;import org.springframework.cloud.consul.ConditionalOnConsulEnabled;import org.springframework.cloud.consul.discovery.ConsulDiscoveryClientConfiguration;import org.springframework.cloud.consul.discovery.TtlScheduler;import org.springframework.cloud.consul.serviceregistry.ConsulServiceRegistryAutoConfiguration;import org.springframework.cloud.consul.support.ConsulHeartbeatAutoConfiguration;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;/** * @Author luhaijun * @Description 重新定义YJConsulHeartbeatAutoConfiguration * @Date 2019/10/8 11:40 AM **/@Configuration@ConditionalOnConsulEnabled@ConditionalOnProperty({"spring.cloud.consul.discovery.heartbeat.enabled"})@ConditionalOnDiscoveryEnabled@AutoConfigureBefore({ConsulServiceRegistryAutoConfiguration.class, ConsulHeartbeatAutoConfiguration.class})@AutoConfigureAfter({ConsulDiscoveryClientConfiguration.class})public class YJConsulHeartbeatAutoConfiguration {@Value("${spring.cloud.consul.discovery.acl-token:null}")private String token;public YJConsulHeartbeatAutoConfiguration() {
    }@Bean    public YJHeartbeatProperties yjHeartbeatProperties() {return new YJHeartbeatProperties();
    }@Bean    public TtlScheduler ttlScheduler(YJHeartbeatProperties yjHeartbeatProperties, ConsulClient consulClient) {return new YJTtlScheduler(yjHeartbeatProperties, consulClient, token);
    }
}

2.重写心跳Scheduler

package com.support.consul;import com.ecwid.consul.v1.ConsulClient;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.cloud.consul.discovery.TtlScheduler;import org.springframework.scheduling.TaskScheduler;import org.springframework.scheduling.concurrent.ConcurrentTaskScheduler;import java.util.Map;import java.util.concurrent.ConcurrentHashMap;import java.util.concurrent.Executors;import java.util.concurrent.ScheduledFuture;/** * @Author lbm * @Date 2019/10/3 4:54 下午 * @Description 重写心跳Scheduler **/public class YJTtlScheduler extends TtlScheduler {private static final Log log = LogFactory.getLog(YJTtlScheduler.class);private final Map serviceHeartbeats = new ConcurrentHashMap<>();private final TaskScheduler scheduler = new ConcurrentTaskScheduler(Executors.newSingleThreadScheduledExecutor());private YJHeartbeatProperties configuration;private ConsulClient client;private String token;public YJTtlScheduler(YJHeartbeatProperties configuration, ConsulClient client, String token) {super(null, null);this.configuration = configuration;this.client = client;this.token = token;
    }@Override    public void add(String instanceId) {
        ScheduledFuture task = this.scheduler.scheduleAtFixedRate(new YJTtlScheduler.ConsulHeartbeatTask(instanceId), this.configuration.computeHeartbeatInterval().toStandardDuration().getMillis());
        ScheduledFuture previousTask = (ScheduledFuture) this.serviceHeartbeats.put(instanceId, task);if (previousTask != null) {
            previousTask.cancel(true);
        }log.info("Add Consul heartbeat for: " + instanceId);
    }@Override    public void remove(String instanceId) {
        ScheduledFuture task = (ScheduledFuture) this.serviceHeartbeats.get(instanceId);if (task != null) {
            task.cancel(true);
        }this.serviceHeartbeats.remove(instanceId);
    }private class ConsulHeartbeatTask implements Runnable {private String checkId;

        ConsulHeartbeatTask(String serviceId) {this.checkId = serviceId;if (!this.checkId.startsWith("service:")) {this.checkId = "service:" + this.checkId;
            }
        }@Override        public void run() {//调用ConsulClient api 带token方法            YJTtlScheduler.this.client.agentCheckPass(this.checkId, null, token);if (log.isDebugEnabled()) {log.debug("Sending consul heartbeat for: " + this.checkId + ", token: " + token);
            }
        }
    }
}

3.自己配置HeartbeatProperties

package com.support.consul;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.joda.time.Period;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.core.style.ToStringCreator;import org.springframework.validation.annotation.Validated;import javax.validation.constraints.DecimalMax;import javax.validation.constraints.DecimalMin;import javax.validation.constraints.Min;import javax.validation.constraints.NotNull;@ConfigurationProperties(
        prefix = "spring.cloud.consul.discovery.heartbeat")@Validatedpublic class YJHeartbeatProperties {private static final Log log = LogFactory.getLog(YJHeartbeatProperties.class);boolean enabled = false;@Min(1L)private int ttlValue = 30;@NotNull    private String ttlUnit = "s";@DecimalMin("0.1")@DecimalMax("0.9")private double intervalRatio = 0.6666666666666666D;public YJHeartbeatProperties() {
    }protected Period computeHeartbeatInterval() {double interval = (double)this.ttlValue * this.intervalRatio;double max = Math.max(interval, 1.0D);int ttlMinus1 = this.ttlValue - 1;double min = Math.min((double)ttlMinus1, max);
        Period heartbeatInterval = new Period(Math.round(1000.0D * min));log.debug("Computed heartbeatInterval: " + heartbeatInterval);return heartbeatInterval;
    }public String getTtl() {return this.ttlValue + this.ttlUnit;
    }public boolean isEnabled() {return this.enabled;
    }public void setEnabled(boolean enabled) {this.enabled = enabled;
    }@Min(1L)public int getTtlValue() {return this.ttlValue;
    }public void setTtlValue(@Min(1L) int ttlValue) {this.ttlValue = ttlValue;
    }@NotNull    public String getTtlUnit() {return this.ttlUnit;
    }public void setTtlUnit(@NotNull String ttlUnit) {this.ttlUnit = ttlUnit;
    }@DecimalMin("0.1")@DecimalMax("0.9")public double getIntervalRatio() {return this.intervalRatio;
    }public void setIntervalRatio(@DecimalMin("0.1") @DecimalMax("0.9") double intervalRatio) {this.intervalRatio = intervalRatio;
    }@Override    public String toString() {return (new ToStringCreator(this)).append("enabled", this.enabled).append("ttlValue", this.ttlValue).append("ttlUnit", this.ttlUnit).append("intervalRatio", this.intervalRatio).toString();
    }
}
