springboot和solr结合测试使用
首先新建springboot项目
新建webapp目录
springboot没有webapp目录——手动添加
web.xml

controller：SolrController.java
package com.xiaostudy.solr_test1.web.controller; import com.xiaostudy.solr_test1.base.User; import org.apache.solr.client.solrj.SolrClient; import org.apache.solr.client.solrj.SolrQuery; import org.apache.solr.client.solrj.SolrServerException; import org.apache.solr.client.solrj.response.QueryResponse; import org.apache.solr.client.solrj.response.UpdateResponse; import org.apache.solr.common.SolrDocument; import org.apache.solr.common.SolrDocumentList; import org.apache.solr.common.util.NamedList; import org.springframework.beans.factory.annotation.Autowired; 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.ArrayList; import java.util.Collection; import java.util.List; import java.util.Map; /** * Created with IntelliJ IDEA. * User: Administrator * Date: 2019/6/2 * Time: 11:14 * Description: No Description */ @RestController public class SolrController { @Autowired private SolrClient solrClient; //批量增加 @RequestMapping("/addUsers") public void addUsers() throws IOException, SolrServerException { List<User> users = new ArrayList<>(); for(int i = 0; i < 3; i++) { User user = new User(); user.setId("123456_" + i); user.setName("xiaostudy_" + i); user.setAddress("广州_" + i); user.setSex("男_" + i); users.add(user); } solrClient.addBeans(users); solrClient.commit(); } //单个增加 @RequestMapping("/addUser") public void addUser() throws IOException, SolrServerException { User user = new User(); user.setId("45678"); user.setName("张三"); user.setAddress("北京市"); user.setSex("女"); solrClient.addBean(user); solrClient.commit(); } //根据id查询 @RequestMapping("/getByIdFromSolr/{id}") public void getByIdFromSolr(@PathVariable("id") String id) throws IOException, SolrServerException { //根据id查询内容 SolrDocument solrDocument = solrClient.getById(id); //获取filedName Collection<String> fieldNames = solrDocument.getFieldNames(); //获取file名和内容 Map<String, Object> fieldValueMap = solrDocument.getFieldValueMap(); // int childDocumentCount = solrDocument.getChildDocumentCount(); List<SolrDocument> childDocuments = solrDocument.getChildDocuments(); System.out.println("byId=================="+solrDocument); System.out.println("fieldNames=================="+fieldNames); System.out.println("fieldValueMap=================="+fieldValueMap); // System.out.println("childDocumentCount=================="+childDocumentCount); System.out.println("childDocuments=================="+childDocuments); } //根据di删除 @RequestMapping("/delById/{id}") public void delById(@PathVariable("id") String id) throws IOException, SolrServerException { //根据id删除信息 UpdateResponse updateResponse = solrClient.deleteById(id); //执行的时间 long elapsedTime = updateResponse.getElapsedTime(); int qTime = updateResponse.getQTime(); //请求地址 String requestUrl = updateResponse.getRequestUrl(); //请求的结果{responseHeader={status=0,QTime=2}} NamedList<Object> response = updateResponse.getResponse(); //请求结果的头{status=0,QTime=2} NamedList responseHeader = updateResponse.getResponseHeader(); //请求的状态 0 int status = updateResponse.getStatus(); System.out.println("elapsedTime==========="+elapsedTime); System.out.println("qTime==========="+qTime); System.out.println("requestUrl==========="+requestUrl); System.out.println("response==========="+response); System.out.println("responseHeader==========="+responseHeader); System.out.println("status==========="+status); } @RequestMapping("/queryFromSolr") public Object queryFromSolr() throws IOException, SolrServerException { //第一种方式 // Map<String, String> queryParamMap = new HashMap<String, String>(); // queryParamMap.put("q", "*:*"); // queryParamMap.put("f1","id,name"); // queryParamMap.put("sort","id asc"); // MapSolrParams mapSolrParams = new MapSolrParams(queryParamMap); // solrClient.query(mapSolrParams); //第二种方式 SolrQuery solrQuery = new SolrQuery(); solrQuery.setQuery("*:*"); // solrQuery.addField("*"); solrQuery.add("q","id:4567"); solrQuery.setSort("id", SolrQuery.ORDER.asc); //设置查询的条数 solrQuery.setRows(50); //设置查询的开始 solrQuery.setStart(0); //设置高亮 solrQuery.setHighlight(true); //设置高亮的字段 solrQuery.addHighlightField("item_name"); //设置高亮的样式 solrQuery.setHighlightSimplePre("<font color='red'>"); solrQuery.setHighlightSimplePost("</font>"); System.out.println(solrQuery); QueryResponse response = solrClient.query(solrQuery); //返回高亮显示结果 Map<String, Map<String, List<String>>> highlighting = response.getHighlighting(); //response.getResults();查询返回的结果 SolrDocumentList documentList = response.getResults(); for (SolrDocument solrDocument : documentList) { System.out.println("solrDocument==============" +solrDocument); } return documentList; } }
测试能不能访问springboot项目，这个可以不要
IndexController.java
package com.xiaostudy.solr_test1.web.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; /** * Created with IntelliJ IDEA. * User: Administrator * Date: 2019/6/2 * Time: 11:15 * Description: No Description */ @Controller public class IndexController { @RequestMapping("/index") public String index() { return "index"; } }
测试
所以这里提示：除了查询，增删改都要提交事务
solrClient.commit();
solrClient.addBean(new User());// 添加一个对象 solrClient.addBeans(users);// 添加多个对象 solrClient.deleteByQuery("*:*");// 删除所有索引 solrClient.deleteById("1234");// 删除id为1234的索引 solrClient.getById("1234");// 查询id为1234的索引
