BaseHttpSolrClient, NoClassDefFoundError HealthContributorAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.health.HealthContributor]: Factory method 'solrHealthContributor' threw exception; nested exception is java.lang.NoClassDefFoundError: org/apache/solr/client/solrj/impl/BaseHttpSolrClient$RemoteSolrException

SpringBoot升級之后, 被項目里面的solr坑了一把

SpringBoot目前版本: 2.3.9-RELEASE
Solrj版本: 7.7.3

因為是另一個同事升級的, 然后現在我負責上線了, 結果發測試環境的時候報BaseHttpSolrClient 這個類沒定義

查了一圈 發現 BaseHttpSolrClient 這個類是solr8.x里面的API, 但是我明明用的是7.7.3, 為什么啟動的時候會去加載這個配置?

然后發現那同事加了一個springboot-actuator在里面, 啟動的時候會對solr做一個健康檢查, 然后健康檢查用是那個actuator指定的solr版本(這里沒有詳細去研究)

解決方式:

1. 自定義Solr的健康檢查

2. 在啟動類@SpringBootApplication里面排除Solr健康檢查自動配置
    

@SpringBootApplication(exclude = {SolrHealthContributorAutoConfiguration.class})
public class Application {
	public static void main(String[] args) throws Exception {
		SpringApplication.run(Application.class, args);
	}

}
