This article focuses on "the use of ConsulAutoConfiguration in spring cloud". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "the use of ConsulAutoConfiguration in spring cloud".

This paper mainly studies the ConsulAutoConfiguration of spring cloud.

ConsulAutoConfiguration

SpringMurphy cloudhouse consortium Murray 2.1.2.RELEASEMohamsources.jarwithorgAccording to springframeworkAccording to consulatory ConsulAutoConfiguration.java

ConsulEndpoint

Springhouse cloudhouse consortium house 2.1.2.RELEASUSue sources.jarUniverse orgAccording frame workbank cloudlap consulatory ConsulEndpoint.java

@ Endpoint (id = "consul") public class ConsulEndpoint {private ConsulClient consul; public ConsulEndpoint (ConsulClient consul) {this.consul = consul;} @ ReadOperation public ConsulData invoke () {ConsulData data = new ConsulData (); / / data.setKeyValues (kvClient.getKeyValueRecurse ()); Response agentServices = this.consul.getAgentServices () Data.setAgentServices (agentServices.getValue ()); Response catalogServices = this.consul .getCatalogServices (QueryParams.DEFAULT); for (String serviceId: catalogServices.getValue (). KeySet ()) {Response response = this.consul .getCatalogService (serviceId, QueryParams.DEFAULT) Data.getCatalogServices () .put (serviceId, response.getValue ());} Response catalogNodes = this.consul .getCatalogNodes (QueryParams.DEFAULT); data.setCatalogNodes (catalogNodes.getValue ()); return data } / * Represents Consul data related to catalog entries and agent servies. * / public static class ConsulData {Map catalogServices = new LinkedHashMap (); Map agentServices; List catalogNodes; public ConsulData () {} public Map getCatalogServices () {return this.catalogServices } public void setCatalogServices (Map catalogServices) {this.catalogServices = catalogServices;} public Map getAgentServices () {return this.agentServices } public void setAgentServices (Map agentServices) {this.agentServices = agentServices;} public List getCatalogNodes () {return this.catalogNodes;} public void setCatalogNodes (List catalogNodes) {this.catalogNodes = catalogNodes } @ Override public String toString () {return new ToStringCreator (this) .append ("catalogServices", this.catalogServices) .append ("agentServices") This.agentServices) .append ("catalogNodes", this.catalogNodes) .toString () }}}

ConsulEndpoint has a ReadOperation, which returns ConsulData, including agentServices, agentServices, and catalogNodes.

ConsulHealthIndicator

SpringMurphy cloudhouse consortium house 2.1.2.RELEASEMohamsources.jarwithorgAccording to springframeworkUniverse cloudlink consulthIndicator.java

Public class ConsulHealthIndicator extends AbstractHealthIndicator {private ConsulClient consul; public ConsulHealthIndicator (ConsulClient consul) {this.consul = consul;} @ Override protected void doHealthCheck (Health.Builder builder) throws Exception {final Response leaderStatus = this.consul.getStatusLeader (); final Response services = this.consul .getCatalogServices (QueryParams.DEFAULT) Builder.up () .withDetail ("leader", leaderStatus.getValue ()) .withdetail ("services", services.getValue ());}}

ConsulHealthIndicator inherits AbstractHealthIndicator, and its doHealthCheck will call ConsulClient.getStatusLeader to get leaderStatus and ConsulClient.getCatalogServices to get catalogServices information.

Summary

ConsulAutoConfiguration registered ConsulClient, ConsulEndpoint, ConsulHealthIndicator

ConsulEndpoint has a ReadOperation, which returns ConsulData, including agentServices, agentServices, and catalogNodes.

ConsulHealthIndicator inherits AbstractHealthIndicator, and its doHealthCheck will call ConsulClient.getStatusLeader to get leaderStatus and ConsulClient.getCatalogServices to get catalogServices information.
