1、solr的配置檔案（solr.properties）

solr.Url=http://localhost:8080/solr/student  （student是例項core）
solr.maxRetries=1
solr.connectionTimeout=500

2、引入solr的配置檔案，並配置bean

<context:property-placeholder location="classpath:/jdbc.properties,classpath:/solr.properties" />

<!--定義solr的server -->
<bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer">
    <constructor-arg index="0" value="${solr.Url}" />
    <!-- 設定響應解析器 -->
    <property name="parser">
	<bean class="org.apache.solr.client.solrj.impl.XMLResponseParser" />
   </property>
   <!-- 設定重試次數 -->
   <property name="maxRetries" value="${solr.maxRetries}" />
   <!-- 建立連線的最長時間 -->
   <property name="connectionTimeout" value="${solr.connectionTimeout}" />
</bean>
 

3、建立學生實體類（注意@Field必須加上）

import org.apache.solr.client.solrj.beans.Field;

public class Student {

	private String id;

	private String stu_name;

	private int age;

	private String stu_school;

	public String getId() {
		return id;
	}

	@Field
	public void setId(String id) {
		this.id = id;
	}

	public String getStu_name() {
		return stu_name;
	}

	@Field
	public void setStu_name(String stu_name) {
		this.stu_name = stu_name;
	}

	public int getAge() {
		return age;
	}

	@Field
	public void setAge(int age) {
		this.age = age;
	}

	public String getStu_school() {
		return stu_school;
	}

	@Field
	public void setStu_school(String stu_school) {
		this.stu_school = stu_school;
	}

	@Override
	public String toString() {
		return "Student [id=" + id + ", stu_name=" + stu_name + ", age=" + age + ", stu_school=" + stu_school + "]";
	}

}
 

4、編寫業務程式碼

import java.io.IOException;
import java.util.List;
import java.util.Map;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.impl.HttpSolrServer;
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.SolrInputDocument;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.jssecco.split.solr.model.Student;

@Controller
@RequestMapping("/solr")
public class SpringSolrController {
	@Autowired
	private HttpSolrServer httpSolrServer;

	/**
	 * 測試方法
	 * 
	 * @param id
	 * @return
	 * @throws SolrServerException
	 */
	@ResponseBody
	@RequestMapping(value = "/getStudent")
	public Student getStudent(Long id) throws SolrServerException {

		// 建立查詢條件
		SolrQuery query = new SolrQuery();
		query.setQuery("id:" + id);
		// 查詢並返回結果
		QueryResponse queryResponse = this.httpSolrServer.query(query);
		return (Student) queryResponse.getBeans(Student.class);
	}

	/**
	 * 新增、修改
	 * 
	 * @param student
	 * @throws SolrServerException
	 * @throws IOException
	 */
	@ResponseBody
	@RequestMapping(value = "/addStudent")
	public void addStudent(@RequestBody Student student) throws SolrServerException, IOException {
		SolrInputDocument doc = new SolrInputDocument();
		doc.addField("id", student.getId());
		doc.addField("stu_name", student.getStu_name());
		doc.addField("age", student.getAge());
		doc.addField("stu_school", student.getStu_school());
		UpdateResponse response = this.httpSolrServer.add(doc);
		this.httpSolrServer.commit(); // 提交
		System.out.println(response);
	}

	/**
	 * 刪除
	 * 
	 * @param student
	 * @throws SolrServerException
	 * @throws IOException
	 */
	@ResponseBody
	@RequestMapping(value = "/delStudent")
	public void delStudent(@RequestBody Student student) throws SolrServerException, IOException {
		UpdateResponse response = this.httpSolrServer.deleteById(student.getId());
		this.httpSolrServer.commit(); // 提交
		System.out.println(response);
	}

	@ResponseBody
	@RequestMapping(value = "/searchStudentList")
	public void searchStudentList() throws SolrServerException {
		// 相當於QueryParser
		SolrQuery query = new SolrQuery("*:*");
		query.setStart(1);
		query.setRows(3);
		QueryResponse res = this.httpSolrServer.query(query);
		// 可以直接查詢相應的bean物件，但是不是很常用
		// 使用這種方式無法獲取總數量
		List<Student> list = res.getBeans(Student.class);
		System.out.println("當前總數：" + list.size());
		for (Student stu : list) {
			System.out.println(stu.getId() + "#" + stu.getStu_name() + "#" + stu.getAge() + "#" + stu.getStu_school());
		}
	}

	@ResponseBody
	@RequestMapping(value = "/testHighlight")
	public void testHighlight() throws SolrServerException {
		// 以後引數都是通過這個物件去構造...
		SolrQuery solrParams = new SolrQuery();
		solrParams.setQuery("stu_name:測試");
		// 開啟高亮
		solrParams.setHighlight(true);
		// 高亮顯示的格式
		solrParams.setHighlightSimplePre("<font color='red'>");
		solrParams.setHighlightSimplePost("</font>");
		// 我需要那幾個欄位進行高亮
		solrParams.setParam("hl.fl", "stu_name");
		QueryResponse queryResponse = this.httpSolrServer.query(solrParams);
		// 返回所有的結果...
		SolrDocumentList documentList = queryResponse.getResults();
		Map<String, Map<String, List<String>>> maplist = queryResponse.getHighlighting();
		// 返回高亮之後的結果..
		for (SolrDocument solrDocument : documentList) {
			Object id = solrDocument.get("id");
			Map<String, List<String>> fieldMap = maplist.get(id);
			List<String> stringlist = fieldMap.get("stu_name");
			System.out.println(stringlist);
		}
	}
}
