如果没有看前两篇文章 请先看前两篇文章 因为该文章有些内容是依托于前两篇文章的。
一、solr的操作类

package com.demo.demo.service;

import com.demo.demo.bean.solr.GoodsSolrEntity;
import org.apache.solr.client.solrj.response.UpdateResponse;
import org.apache.solr.common.SolrInputDocument;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.solr.core.SolrTemplate;
import org.springframework.data.solr.core.query.Criteria;
import org.springframework.data.solr.core.query.SimpleQuery;
import org.springframework.data.solr.core.query.SolrDataQuery;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Map;

/**
 * @program: com.zhangxian.pay.service
 * @author: zwx

 **/
@Service
public class GoodsSolrOperations {
    @Autowired
    private SolrTemplate solrTemplate;

    /**
     * 通过主键ID删除solr数据 批量删除
     * @param ids
     */
    public void deleteSolrById(List<String> ids)
    {
        solrTemplate.deleteByIds("haircut_goods", ids);
        solrTemplate.commit("haircut_goods");
    }
    
	/**
     * 通过条件删除文档
     * @param where
     */
     // ? 是类型通配符 使用类型通配符的原因是  循环添加删除条件无法确定类型
    public void deleteSolrByQuery(Map< String, ? > where)
    {
        SolrDataQuery solrDataQuery = new SimpleQuery();
        for (Map.Entry<String, ?> entry: where.entrySet()) {
          solrDataQuery.addCriteria(Criteria.where(entry.getKey()).is(entry.getValue()));
        }
        solrTemplate.delete("haircut_goods", solrDataQuery);
        solrTemplate.commit("haircut_goods");
    }
}

二、控制器调用

package com.demo.demo.controller;

import com.demo.demo.bean.solr.GoodsSolrEntity;
import com.demo.demo.service.GoodsSolrOperations;
import com.demo.demo.service.impl.HaircutUsers;
import org.apache.poi.ss.formula.functions.T;
import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrServerException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.solr.core.SolrTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.IOException;
import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

@RestController
@RequestMapping("index")
public class IndexController {

    @Autowired
    private HaircutUsers haircutUsers;
    @Autowired
    private SolrClient solrClient;
    @Autowired
    private SolrTemplate solrTemplate;

    @Autowired
    private GoodsSolrOperations goodsSolrOperations;

    @GetMapping("index/{nickname}")
    public void Index(@PathVariable(value = "nickname") String nickname) throws IOException, SolrServerException {
		
		// 根据主键ID批量删除
		goodsSolrOperations.deleteSolrById(Arrays.asList("6", "7"));
		
        Map where = new HashMap();
        where.put("id", "6");
        where.put("store_id", 3);
        where.put("desc", "描述");
        goodsSolrOperations.deleteSolrByQuery(where);
    }
}
