## Solr介绍 ##

Solr具有高度的可靠性，可伸缩性和容错能力，可提供分布式索引，复制和负载平衡查询，自动故障转移和恢复，集中式配置等。Solr为许多世界上最大的互联网站点提供搜索和导航功能。

Solr是具有REST类API的独立企业搜索服务器。您可以通过JSON，XML，CSV或HTTP二进制文件将文档放入其中（称为“索引编制”）。您通过HTTP GET查询它，并接收JSON，XML，CSV或二进制结果。

### 先进的全文本搜索功能 ###

在Lucene ™的支持下，Solr实现了强大的匹配功能，包括短语，通配符，联接，分组等等，跨任何数据类型

### 针对大流量进行了优化 ###

Solr已在全球范围内得到广泛验证

### 基于标准的开放接口-XML，JSON和HTTP ###

Solr使用您用来使应用程序构建快速的工具

### 全面的管理界面 ###

Solr附带内置的响应式管理用户界面，可轻松控制您的Solr实例

### 易于监控 ###

需要深入了解您的实例吗？Solr通过JMX发布负载指标数据

### 高度可扩展和容错 ###

Solr建立在经过实战检验的Apache Zookeeper之上，可以轻松地上下扩展。Solr开箱即用地进行复制，分发，重新平衡和容错。

### 灵活且适应性强，配置简单 ###

Solr's旨在满足您的所有需求，同时简化配置

### 近实时索引 ###

想立即查看您的更新吗？Solr利用Lucene的近实时索引功能来确保您在看到内容时能够看到它

### 可扩展的插件架构 ###

Solr发布了许多定义明确的扩展点，这些扩展点使插入索引和查询时间插件变得容易。当然，由于它是Apache许可的开放源代码，因此您可以更改所需的任何代码！

## 安装 ##

官网下载地址：[http://lucene.apache.org/solr/downloads.html][http_lucene.apache.org_solr_downloads.html]

下载速度可以快很多：[https://download.csdn.net/download/tangcv/12084451][https_download.csdn.net_download_tangcv_12084451]

### windows环境下载 ###

### 我的是solr-7.7.2.zip版本，解压后 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 1][]

bin：solr的命令文件  
contrib：solr的插件  
dist： solr的jar包  
docs: solr文档  
example： solr示例  
licenses： solr证书  
server： solr服务器核心文件

### 配置环境变量方便启动：solr的bin目录 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 2][]

### 启动 ###

solr start

不愿配置环境遍历的

//进入solr bin目录
    solr.cmd start

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 3][]

其它命令
    solr start –p 端口号 单机版启动solr服务（默认端口号8983）
    solr restart –p 端口号 重启solr服务
    solr stop –p 端口号关闭solr服务

打开网页[http://localhost:8983][http_localhost_8983]访问进入solr页面即安装完成。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 4][]

# ![Solrçé¢åè½1][Solr_1] #

# ![Solrçé¢åè½5][Solr_5] #

# spring boot中使用 #

在solr页面创建core

solr create -c demo

![20200106142650190.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 5][]

此时在solr目录下会生成一个demo文件：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 6][]

进入conf目录下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 7][]

在Solr的配置文件里，有两个文件很重要，一个是`solrconfig.xml`，还有一个就是`schema.xml，`Solr版本中（Solr5之前），在创建core的时候，Solr会自动创建好schema.xml，在之后的版本中，生成的managed-schema就是schema.xml,直接把managed-schema文件重命名为schema.xml

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3Rhbmdjdg_size_16_color_FFFFFF_t_70 8][]

基础配置完成

## spring boot项目中增删改查数据 ##

### spring boot中添加solr依赖 ###

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-solr</artifactId>
    </dependency>

### yml配置solr端口信息 ###

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

### 添加实体类 UserSolr ###

import lombok.Data;
    import org.apache.solr.client.solrj.beans.Field;
    
    import java.io.Serializable;
    
    /**

     */
    @Data
    public class UserSolr implements Serializable {
    
        //必须实现可序列化接口，要在网络上传输
        @Field("id")//使用这个注释，里面的名字是根据你在solr数据库中配置的来决定
        private String id;
    
        @Field("item_name")
        private String name;
    
        @Field("item_sex")
        private String sex;
    
        @Field("item_address")
        private String address;
    
        @Field("item_host")
        private Integer host;
    
    }

### SolrService ###

public interface SolrService {
    
        List<UserSolr> addUser();
    }

### SolrServiceImpl ###

@Service
    public class SolrServiceImpl implements SolrService {
    
        @Override
        public List<UserSolr> addUser() {
            List<UserSolr> list = new ArrayList<>();
            UserSolr user = new UserSolr();
            for (int i = 0; i <5 ; i++) {
                user.setId(UUID.randomUUID().toString().replace("-",""));
                user.setName("jack"+i);
                if( i % 2 ==0) {
                    user.setSex("男");
                }else {
                    user.setSex("女");
                }
                user.setAddress("兰州市安宁区666"+i);
                user.setHost(73040+i);
                list.add(user);
            }
            return list;
        }
    }
