Springboot中BaseHttpSolrClient报NoClassDefFoundError问题

SpringBoot升级之后, 被项目里面的solr坑了一把

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

因为是另一个同事升级的, 然后现在我负责上线了, 结果发测试环境的时候报BaseHttpSolrClient 这个类没定义

查了一圈 发现 BaseHttpSolrClient 这个类是solr8.x里面的API, 但是我明明用的是7.7.3, 为什么启动的时候会去加载这个配置?

然后发现那同事加了一个springboot-actuator在里面, 启动的时候会对solr做一个健康检查, 然后健康检查用是那个actuator指定的solr版本(这里没有详细去研究)

解决方式:

1. 自定义Solr的健康检查

2. 在启动类@SpringBootApplication里面排除Solr健康检查自动配置
    

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

}
