虽然支持任何编程语言的能力具有很大的市场价值，你可能感兴趣的问题是：我如何将Solr 的应用集成到 Spring 中？可以，Spring Data Solr 就是为了方便 Solr 的开发所研制的一个框架，其底层是对 SolrJ（官方 API）的封装。

第一步：搭建一个maven工程，使用jar

第二步：在pom.xml文件中引入依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0modelVersion>
  <groupId>com.echo.solrgroupId>
  <artifactId>springdatasolrDemoartifactId>
  <version>0.0.1-SNAPSHOTversion>
  <name>springdatasolrDemoname>

    <dependencies>
        <dependency>
        <groupId>org.springframework.datagroupId>
        <artifactId>spring-data-solrartifactId>
        <version>1.5.5.RELEASEversion>
        dependency>
        <dependency>
        <groupId>org.springframeworkgroupId>
        <artifactId>spring-testartifactId>
        <version>4.2.4.RELEASEversion>
        dependency>
        <dependency>
        <groupId>junitgroupId>
        <artifactId>junitartifactId>
        <version>4.9version>
        dependency>
    dependencies>

project>

第三步：在classpath路径下编一个applicationContext-solr.xml文件

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:solr="http://www.springframework.org/schema/data/solr"
    xsi:schemaLocation="http://www.springframework.org/schema/data/solr 
        http://www.springframework.org/schema/data/solr/spring-solr-1.0.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

    
    <solr:solr-server id="solrServer" url="http://127.0.0.1:8080/solr" />

    
    <bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
        <constructor-arg ref="solrServer" />
    bean>
beans>

准备工作做好啦，解析来就可以编写开发程序了，注意：开发需要用到一个特殊的注解@Field。变量上面标注该注解表示这个属性对应域名对应属性名，如果字段和域名不一致，后面添加一个名字即可，如：@Field("item_title") private String title;

第四步：编写一个实体类，并写上相应的注解

package com.echo.pojo;

import java.io.Serializable;
import java.math.BigDecimal;
import java.util.Date;

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

public class TbItem implements Serializable{

    @Field
    private Long id;

     @Field("item_title")
    private String title;

    private String sellPoint;

    @Field("item_price")
    private BigDecimal price;

    private Integer stockCount;

    private Integer num;

    private String barcode;

    @Field("item_image")
    private String image;

    private Long categoryid;

    private String status;

    private Date createTime;

    private Date updateTime;

    private String itemSn;

    private BigDecimal costPirce;

    private BigDecimal marketPrice;

    private String isDefault;

    @Field("item_goodsId")
    private Long goodsId;

    private String sellerId;

    private String cartThumbnail;

    @Field("item_category")
    private String category;

    @Field("item_brand")
    private String brand;

    private String spec;

    @Field("item_seller")
    private String seller;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title == null ? null : title.trim();
    }

    public String getSellPoint() {
        return sellPoint;
    }

    public void setSellPoint(String sellPoint) {
        this.sellPoint = sellPoint == null ? null : sellPoint.trim();
    }

    public BigDecimal getPrice() {
        return price;
    }

    public void setPrice(BigDecimal price) {
        this.price = price;
    }

    public Integer getStockCount() {
        return stockCount;
    }

    public void setStockCount(Integer stockCount) {
        this.stockCount = stockCount;
    }

    public Integer getNum() {
        return num;
    }

    public void setNum(Integer num) {
        this.num = num;
    }

    public String getBarcode() {
        return barcode;
    }

    public void setBarcode(String barcode) {
        this.barcode = barcode == null ? null : barcode.trim();
    }

    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image == null ? null : image.trim();
    }

    public Long getCategoryid() {
        return categoryid;
    }

    public void setCategoryid(Long categoryid) {
        this.categoryid = categoryid;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status == null ? null : status.trim();
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }

    public String getItemSn() {
        return itemSn;
    }

    public void setItemSn(String itemSn) {
        this.itemSn = itemSn == null ? null : itemSn.trim();
    }

    public BigDecimal getCostPirce() {
        return costPirce;
    }

    public void setCostPirce(BigDecimal costPirce) {
        this.costPirce = costPirce;
    }

    public BigDecimal getMarketPrice() {
        return marketPrice;
    }

    public void setMarketPrice(BigDecimal marketPrice) {
        this.marketPrice = marketPrice;
    }

    public String getIsDefault() {
        return isDefault;
    }

    public void setIsDefault(String isDefault) {
        this.isDefault = isDefault == null ? null : isDefault.trim();
    }

    public Long getGoodsId() {
        return goodsId;
    }

    public void setGoodsId(Long goodsId) {
        this.goodsId = goodsId;
    }

    public String getSellerId() {
        return sellerId;
    }

    public void setSellerId(String sellerId) {
        this.sellerId = sellerId == null ? null : sellerId.trim();
    }

    public String getCartThumbnail() {
        return cartThumbnail;
    }

    public void setCartThumbnail(String cartThumbnail) {
        this.cartThumbnail = cartThumbnail == null ? null : cartThumbnail.trim();
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category == null ? null : category.trim();
    }

    public String getBrand() {
        return brand;
    }

    public void setBrand(String brand) {
        this.brand = brand == null ? null : brand.trim();
    }

    public String getSpec() {
        return spec;
    }

    public void setSpec(String spec) {
        this.spec = spec == null ? null : spec.trim();
    }

    public String getSeller() {
        return seller;
    }

    public void setSeller(String seller) {
        this.seller = seller == null ? null : seller.trim();
    }
}

第五步：创建一个测试类往solr操作数据

package test;

import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.List;

import org.junit.Test;
import org.junit.runner.RunWith;
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.Query;
import org.springframework.data.solr.core.query.SimpleQuery;
import org.springframework.data.solr.core.query.result.ScoredPage;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.echo.pojo.TbItem;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext-solr.xml")
public class TestAdd {

    @Autowired
    private SolrTemplate solrTemplate;

    /**
     * 添加一个对象
     */
    @Test
    public void testAdd() {
        TbItem item = new TbItem();
        item.setId(1L);
        item.setBrand("超级手机");
        item.setCategory("手机");
        item.setGoodsId(1L);
        item.setSeller("超级手机国际专卖店");
        item.setTitle("超级手机第1代");
        item.setPrice(new BigDecimal(2000000));
        solrTemplate.saveBean(item);
        solrTemplate.commit();
    }

    /**
     * 根据ID查询一个对象
     */
    @Test
    public void testFindById() {
        TbItem item = solrTemplate.getById(1L, TbItem.class);
        System.out.println(item.getTitle());
    }

    /**
     * 根据ID删除一个对象
     */
    @Test
    public void testDelById() {
        solrTemplate.deleteById("1");
        solrTemplate.commit();
    }

    /**
     * 批量插入数据，插入一个List集合
     */
    @Test
    public void testAddList() {
        List list = new ArrayList();
        for (int i = 0; i < 10; i++) {
            TbItem item = new TbItem();
            item.setId(i + 1L);
            item.setBrand("超级手机" + i);
            item.setCategory("手机");
            item.setGoodsId(1L);
            item.setSeller("超级手机国际专卖店" + i);
            item.setTitle("超级手机第1代" + i);
            item.setPrice(new BigDecimal(20000 + i));
            list.add(item);
        }
        solrTemplate.saveBeans(list);
        solrTemplate.commit();
    }

    /**
     * 分页查询
     */
    @Test
    public void testPageQuery(){
        Query query = new SimpleQuery("*:*");//查询所有数据
        query.setOffset(0);//开始索引（默认0）
        query.setRows(3);//每页记录数（默认10）
        ScoredPage page = solrTemplate.queryForPage(query, TbItem.class);
        System.out.println("总记录数：" + page.getTotalElements());
        List list = page.getContent();
        for(TbItem item : list){
            System.out.println(item.getTitle());
        }
    }

    /**
     * 根据条件查询
     */
    @Test
    public void testCriteriaPageQuery(){
        Query query = new SimpleQuery("*:*");
        //Criteria criteria = new Criteria("item_title").contains("2");//标题中包含2的记录
        Criteria criteria = new Criteria("item_category").contains("手机");//分类中包含手机的
        query.addCriteria(criteria);
        ScoredPage page = solrTemplate.queryForPage(query, TbItem.class);
        System.out.println("总记录数：" + page.getTotalElements());
        List list = page.getContent();
        for(TbItem item : list){
            System.out.println(item.getTitle() + item.getPrice());
        }

    }

    /**
     * 删除全部记录(条件删除和条件查询一样，主要在于构建条件)
     */
    @Test
    public void testDelAll(){
        Query query = new SimpleQuery("*:*");
        solrTemplate.delete(query);
        solrTemplate.commit();
    }
}

执行程序并访问地址http://localhost:8080/solr/，如果出现以上存入的数据代表成功

总结：其实比较简单，主要是导入配置文件，注入Bean，然后使用solr
