Java Spring Data Solr无法在构造函数中创建CRUD实现-NPE

创建名为“classifierSolrRepository”的bean时出现

错误：调用init方法失败；嵌套异常为org.springframework.beans.beanstantiationException:未能实例化[org.springframework.data.solr.repository.support.SimpleSolrRepository]：构造函数引发异常；嵌套异常是java.lang.NullPointerException

分类器索尔还原类：

public interface ClassifierSolrRepository extends SolrCrudRepository<ClassifierSolr, String>
{   

    public List<ClassifierSolr> findByClassifierid(long id);

    public List<ClassifierSolr> findByLanguage(String language);

    public ClassifierSolr findByLanguageAndClassifierid(String language, long id);

    public ClassifierSolr findByLanguageAndCode(String language, String code);

}

最后是我的Solr配置：

@Configuration
@PropertySource("classpath:application.properties")
@EnableSolrRepositories("lt.gerasolutions.gsm.core.solrRepositories")
public class SolrContext {

      private static final String PROPERTY_NAME_SOLR_SERVER_URL = "solr.host";


      @Resource
      private Environment environment;

      @Bean 
      public SolrClient solrClient(){
          return new HttpSolrClient(environment.getRequiredProperty(PROPERTY_NAME_SOLR_SERVER_URL));
      }

      @Bean 
      public SolrTemplate solrTemplate(){
          //return new SolrTemplate(solrClient(), "Classifiers");
          return new SolrTemplate(solrClient());
      }

}

---

我认为它失败的唯一原因是方法名和字段不匹配，但这里的情况似乎不是这样

如果有人遇到同样的问题-它不起作用，因为我有

solr-solrj/solr-core

以及

spring-data-solr

maven依赖项。当我删除了除spring data solr之外的所有内容后（并相应地将

SolrClient

更改为

SolrServer

），一切都开始工作了

@Configuration
@PropertySource("classpath:application.properties")
@EnableSolrRepositories("lt.gerasolutions.gsm.core.solrRepositories")
public class SolrContext {

      private static final String PROPERTY_NAME_SOLR_SERVER_URL = "solr.host";


      @Resource
      private Environment environment;

      @Bean 
      public SolrClient solrClient(){
          return new HttpSolrClient(environment.getRequiredProperty(PROPERTY_NAME_SOLR_SERVER_URL));
      }

      @Bean 
      public SolrTemplate solrTemplate(){
          //return new SolrTemplate(solrClient(), "Classifiers");
          return new SolrTemplate(solrClient());
      }

}
