SOLR的执行器运行状况检查，导致创建名称为'solrClient'的bean时出错

编程问答 2022-08-13

问题描述

我有一个简单的Spring引导应用程序，想要包括对SOLR的执行器运行状况检查，但运行时似乎给出了错误。需要添加或配置的其他任何内容。

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“ actuatorConfiguration”的bean时出错：通过字段“ solr”表示的不满足的依赖关系；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建在类路径资源[org / springframework / boot / autoconfigure / solr / SolrAutoConfiguration.class]中定义的名称为'solrClient'的bean时出错：通过工厂方法的Bean实例化失败；嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.apache.solr.client.solrj.solrClient]：工厂方法“ solrClient”抛出了异常；嵌套的异常是java.lang.NoClassDefFoundError：org / apache / solr / client / solrj / impl / HttpSolrClient $ Builder

  1. SolrHealthindicator.java 
import org.springframework.boot.actuate.health.AbstractHealthindicator;
import org.springframework.boot.actuate.health.Health;
import org.springframework.boot.actuate.health.Status;
import org.apache.solr.client.solrj.solrClient;
import org.apache.solr.client.solrj.request.CoreAdminRequest;
import org.apache.solr.client.solrj.response.CoreAdminResponse;
import org.apache.solr.common.params.CoreAdminParams;


public class SolrHealthindicator extends AbstractHealthindicator {

    private final SolrClient solrClient;

    public SolrHealthindicator(SolrClient solrClient) {
        super("Solr health check Failed");
        this.solrClient = solrClient;
    }

    @Override
    protected void doHealthCheck(Health.Builder builder) throws Exception {
         Object status = this.solrClient.ping().getResponse().get("status");
            builder.up().withDetail("solrstatus",status);
//      CoreAdminRequest request = new CoreAdminRequest();
//      request.setAction(CoreAdminParams.CoreAdminAction.STATUS);
//      CoreAdminResponse response = request.process(this.solrClient);
//      int statusCode = response.getStatus();
//      Status status = (statusCode != 0) ? Status.DOWN : Status.UP;
//      builder.status(status).withDetail("status",statusCode);
    }
}
  1. ActuatorConfiguration.java 
import javax.inject.Inject;
import javax.inject.Named;

import org.apache.solr.client.solrj.solrClient;
import org.springframework.boot.actuate.health.Healthindicator;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class ActuatorConfiguration {

    @Inject
    @Named("solrClient")
    private SolrClient solr;

    @ConditionalOnProperty(value = "solr.health.check.enabled",havingValue = "true")
    @Bean(name = "SearchStorage")
    public Healthindicator solrHealthindicator() {
        return new SolrHealthindicator(solr);
    }
}

解决方法

你连接了 spring-boot-autoconfigure 它有 org.springframework.boot.autoconfigure.solr.SolrAutoConfiguration

并且此代码正在尝试使用 Solr4。 然后你在 pom.xml 中连接了 Solr5。

在 Solr5 中，org/apache/solr/client/solrj/impl/HttpSolrClient$Builder 被移除。

所以解决方案：

  • 禁用 SolrAutoConfiguration。

我也不知道这一点，并在上找到了解决方案 How to Disable SolrAutoConfiguration.class in Grails 3.0.2

// Grails 4
@CompileStatic
@EnableAutoConfiguration(exclude = [org.springframework.boot.autoconfigure.solr.SolrAutoConfiguration.class])
class Application extends GrailsAutoConfiguration {
  • 或更新库
