Spring Boot整合solr进行增删查改

这也是我前段时间所学的，今天整理下发出来

1首先，我们先创建一个项目出来

这个就不用我来演示把，最基本的

2打开你solr服务器

1.1找到你solr安装程序bin目录那里

1.2选中后敲cmd回车弹出控制面板。在里面输出命令 solr.cmd start. 一定要注意命令之间的
间距

默认端口是8983. 重启服务的指令solr.cmd restart -p 8983
启动完成后就可以开始我们项目了

1.3首先建完项目后大致上是这样的

1.4在我们的实体类中写几个参数，因为这里我偷懒了，只写了两个，

package com.xiaogan.springbootsolr.entity;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.apache.solr.client.solrj.beans.Field;

/**

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Product {
    @Field
    private String id;

    @Field
    private String name;



}

这里你的id和name一定要和你solr配置的一样，其它参数也是

1.5差点忘记了，导个pom依赖把

<properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <spring-boot.version>2.3.0.RELEASE</spring-boot.version>
    </properties>

    <dependencies>
        <!--springBoot核心依赖，捉供了核心功能-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <!--引入web starter启动器 常见的场景-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--solr-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-solr</artifactId>
        </dependency>
        <!-- 默认 starter 会加载 solrj 进来, 下面这个可不引-->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-solr</artifactId>
        </dependency>

        <!--lombok-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.10</version>
            <scope>provided</scope>
        </dependency>
        <!--junit测试-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
    </dependencies>

1.6接下来是yml文件配置

spring:
   data:
     solr:
        host: http://localhost:8983/solr/new_core

接下来就是你的控制层

package com.xiaogan.springbootsolr.contrller;

import com.xiaogan.springbootsolr.entity.Product;
import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrServerException;
import org.apache.solr.client.solrj.response.UpdateResponse;
import org.apache.solr.common.SolrDocument;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.IOException;

/**
 * 作者: XiaoGan
 * 时间: 2020/9/1 22:17
 * 描述:
 */
@RestController
public class UserController {
    @Autowired
    private SolrClient solrClient;

    /**
     *查询
     * @throws IOException
     * @throws SolrServerException
     */
    @RequestMapping("/selectId")
    public void selectId() throws IOException, SolrServerException {
            SolrDocument solrDocument = solrClient.getById("1001");
            Product bean = solrClient.getBinder().getBean(Product.class, solrDocument);
            System.out.println("bean =" + bean);
    }

    /**
     * 删除
     * @throws IOException
     * @throws SolrServerException
     */
    @RequestMapping("/deleteId")
    public void deleteId() throws IOException, SolrServerException {
        UpdateResponse updateResponse = solrClient.deleteById("1001");
        solrClient.commit();
        int status = updateResponse.getStatus();
        System.out.println("status = " + status);
    }

    /**
     * 添加
     * @throws IOException
     * @throws SolrServerException
     */
    @RequestMapping("testId")
    public void testAddProductDocument1() throws IOException, SolrServerException {
        Product product = new Product().builder()
                .id("1001")
                .name("某某的劳斯莱斯")
                .build();
        UpdateResponse updateResponse =solrClient.addBean(product);
        solrClient.commit();
        int status = updateResponse.getStatus();
        System.out.println("status = " + status);
        updateResponse = solrClient.addBean(product);

    }
    /**
     * 修改
     */
    @RequestMapping("updateId")
    public void updateId() throws IOException, SolrServerException {
        Product product = new Product().builder()
                .id("1002")
                .name("某某的劳斯莱斯")
                .build();
        UpdateResponse updateResponse =solrClient.addBean(product);
        solrClient.commit();
        int status = updateResponse.getStatus();
        System.out.println("status = " + status);
        updateResponse = solrClient.addBean(product);

    }

}

我这个因为写的还是挺简单的，你们接下来一个个测试就行了，
也没啥东西，今天这个就到此结束了
