Question

我一直在努力寻找这个问题的解决方案，我试图在这里解释一下。非常感谢我可以尝试的一些想法，以解决这个问题。

我们将Spring Web Services与Microsoft SQL Server作为后端。我们一直致力于SQL到SOLR迁移项目，我们需要将所有SQL数据索引到SOLR并在那里执行搜索，因为我们的应用程序一直面临很多性能问题。

我们采取的基本方法如下：

1）如此处所述创建SOLR EAR

2）在DEV env中的IBM Websphere v7.0上部署SOLR EAR

3）在LOCAL

中的Websphere服务器上部署Spring Web Services EAR

4）以下是我们如何尝试从Web服务访问核心。这里，我展示了一个内核的示例，而在实际代码中，我们以相同的方式访问多个内核。

spring.xml

：/ solr的/ collection1 /“/＆GT;

SearchEngineRepositoryImpl.java

package com.example.solr.repository;

import javax.annotation.Resource;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Sort;
import org.springframework.data.geo.Circle;
import org.springframework.data.solr.core.SolrTemplate;
import org.springframework.data.solr.core.query.Criteria;
import org.springframework.data.solr.core.query.FacetOptions;
import org.springframework.data.solr.core.query.SimpleFacetQuery;
import org.springframework.data.solr.core.query.SimpleQuery;
import org.springframework.data.solr.core.query.result.FacetEntry;
import org.springframework.data.solr.core.query.result.FacetPage;
import org.springframework.stereotype.Repository;

@Repository
public class SearchEngineRepositoryImpl implements SearchEngineRepository{

  @Resource
  private SolrTemplate solrTemplateCollection1;

  public List<SearchDocument> search(SearchCriteria searchCriteria){

    Criteria solrSearchCriteira  = new Criteria("name").contains(searchCriteria.getName());

    SimpleFacetQuery searchQuery = new SimpleFacetQuery(solrSearchCriteira);

    FacetPage<SearchDocument> results =  solrTemplateCollection1.queryForFacetPage(searchQuery,SearchDocument.class);

    // rest of code
    .
    .
    .
  }
}

当我尝试运行Web服务时，我遇到以下异常：

我可以在浏览器中调用SOLR控制台和其他SOLR查询。

此外，当我在同一个Websphere服务器上部署Web服务和SOLR EAR时（即在spring.xml中将主机名更改为localhost后），我得到了正确的响应。

SOLR EAR的web.xml中没有身份验证设置。
