Question

基本上，我需要从Solr索引和查询数据。因此，首先，我尝试创建一个HttpSolrClient并面对该问题。在项目中添加的依赖项是：

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Edgware.SR5</spring-cloud.version>

    <slf4j.version>1.7.7</slf4j.version>
    <commons-lang3.version>3.5</commons-lang3.version>
</properties>

运行Maven依赖树。结果如下： mvn依赖项：tree | grep solr [INFO] +-org.apache.solr：solr-core：jar：7.5.0：compile [INFO] | +-org.apache.solr：solr-solrj：jar：7.5.0：compile

在存储库中，solr文件夹只有3个子文件夹。 1. solr-core，2. solr-parent，3. solr-solrj

尝试在调试模式下运行mvn。 mvnDebug全新安装-X 获取以下错误信息：

申请无法开始

说明：

尝试调用方法org.apache.solr.client.solrj.impl.HttpSolrClient。（Ljava / lang / String;）V，但该方法不存在。可从以下位置获得其类org.apache.solr.client.solrj.impl.HttpSolrClient。

jar:file:/Users/admin/.m2/repository/org/apache/solr/solr-solrj/7.5.0/solr-solrj-7.5.0.jar!/org/apache/solr/client/solrj/impl/HttpSolrClient.class

它是从以下位置加载的：

file:/Users/admin/.m2/repository/org/apache/solr/solr-solrj/7.5.0/solr-solrj-7.5.0.jar

操作：

更正应用程序的类路径，使其包含org.apache.solr.client.solrj.impl.HttpSolrClient的单个兼容版本

java.lang.IllegalStateException：无法加载ApplicationContext

原因：org.springframework.beans.factory.BeanCreationException：在类路径资源[org / springframework / boot / autoconfigure / solr / SolrAutoConfiguration.class]中创建名称为'solrClient'的bean时出错：通过工厂方法实例化Bean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'引发了异常；嵌套异常是java.lang.NoSuchMethodError：org.apache.solr.client.solrj.impl.HttpSolrClient。（Ljava / lang / String;）V

原因：org.springframework.beans.BeanInstantiationException：无法实例化[org.apache.solr.client.solrj.SolrClient]：工厂方法“ solrClient”抛出异常；嵌套异常是java.lang.NoSuchMethodError：org.apache.solr.client.solrj.impl.HttpSolrClient。（Ljava / lang / String;）V

由以下原因引起：java.lang.NoSuchMethodError：org.apache.solr.client.solrj.impl.HttpSolrClient。（Ljava / lang / String;）V

private HttpSolrClient solrClient;

public SolrJavaIntegration(String clientUrl) {
    solrClient = new HttpSolrClient.Builder(clientUrl).build();
}

需要能够创建HttpSolrClient且没有任何问题，但是有问题。

Answer 1

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

禁用 SolrAutoConfiguration ，它可能会起作用

由以下原因引起：java.lang.NoSuchMethodError：org.apache.solr.client.solrj.impl.HttpSolrClient。<init>（Ljava / lang / String;）V
