Spring Data Solr入门

2.1 Spring Data Solr简介

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。

2.2 Spring Data Solr入门小Demo

2.2.1 搭建工程

（1）创建maven工程，pom.xml中引入依赖

<groupId>org.springframework.data</groupId>

<artifactId>spring-data-solr</artifactId>

<version>1.5.5.RELEASE</version>

</dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-test</artifactId>

<version>4.2.4.RELEASE</version>

</dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

</dependency>

</dependencies>

（2）在src/main/resources下创建 applicationContext-solr.xml

<?xml version="1.0" encoding="UTF-8"?>

<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://192.168.188.128:8080/solr" />

<constructor-arg ref="solrServer" />

</bean>

</beans>

2.2.2 @Field 注解

创建 com.offfcn.pojo 包，将优乐选的TbItem实体类拷入本工程 ,属性使用@Field注解标识。如果属性与配置文件定义的域名称不一致，需要在注解中指定域名称。

package com.offfcn.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;

    }

    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) {

    }

    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() {

    }

    public String getSeller() {
        return seller;
    }

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

2.2.3 增加（修改）

创建测试类TestTemplate.java

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations="classpath:applicationContext-solr.xml")

public class TestTemplate {

@Autowired

private SolrTemplate solrTemplate;

@Test

public void testAdd(){

TbItem item=new TbItem();

item.setId(1L);

item.setBrand("华为");

item.setCategory("手机");

item.setGoodsId(1L);

item.setSeller("华为2号专卖店");

item.setTitle("华为Mate9");

item.setPrice(new BigDecimal(2000));

solrTemplate.saveBean(item);

solrTemplate.commit();

}

2.2.4 按主键查询

@Test

public void testFindOne(){

TbItem item = solrTemplate.getById(1, TbItem.class);

System.out.println(item.getTitle());

}

2.2.5 按主键删除

@Test

public void testDelete(){

solrTemplate.deleteById("1");

solrTemplate.commit();

}

2.2.6 分页查询

首先循环插入100条测试数据

@Test

public void testAddList(){

List<TbItem> list=new ArrayList();

for(int i=0;i<100;i++){

TbItem item=new TbItem();

item.setId(i+1L);

item.setBrand("华为");

item.setCategory("手机");

item.setGoodsId(1L);

item.setSeller("华为2号专卖店");

item.setTitle("华为Mate"+i);

item.setPrice(new BigDecimal(2000+i));

list.add(item);

}

solrTemplate.saveBeans(list);

solrTemplate.commit();

}

编写分页查询测试代码：

@Test

public void testPageQuery(){

Query query=new SimpleQuery("*:*");

query.setOffset(20);//开始索引（默认0）

query.setRows(20);//每页记录数(默认10)

ScoredPage<TbItem> page = solrTemplate.queryForPage(query, TbItem.class);

System.out.println("总记录数："+page.getTotalElements());

List<TbItem> list = page.getContent();

showList(list);

}

//显示记录数据

private void showList(List<TbItem> list){

for(TbItem item:list){

System.out.println(item.getTitle() +item.getPrice());

}

2.2.7 条件查询

Criteria 用于对条件的封装：

@Test

public void testPageQueryMutil(){

Query query=new SimpleQuery("*:*");

Criteria criteria=new Criteria("item_title").contains("2");

criteria=criteria.and("item_title").contains("5");

query.addCriteria(criteria);

//query.setOffset(20);//开始索引（默认0）

//query.setRows(20);//每页记录数(默认10)

ScoredPage<TbItem> page = solrTemplate.queryForPage(query, TbItem.class);

System.out.println("总记录数："+page.getTotalElements());

List<TbItem> list = page.getContent();

showList(list);

}

2.2.8 删除全部数据

@Test

public void testDeleteAll(){

Query query=new SimpleQuery("*:*");

solrTemplate.delete(query);

solrTemplate.commit();

}
