  • 全量导入数据
curl http://localhost:8983/solr/core-practice/dataimport?command=full-import
  • 增量导入数据
curl http://localhost:8983/solr/core-practice/dataimport?command=delta-import
  • 查询导入数据
curl http://localhost:8983/solr/core-practice/select?q=*:* | json

这里使用nodejs的json工具格式化数据: npm i -g json、

Startup

spring init -dweb,data-solr --build gradle SolrPractice
# cd SolrPractice
mv src/main/resources/application.properties src/main/resources/application.yml
vim src/main/resources/application.yml
spring:
  data:
    solr:
      host: http://127.0.0.1:8983/solr/
vim src/main/java/com/example/SolrPractice/ArticleController.java
package com.example.SolrPractice;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/articles")
public class ArticleController {
    @GetMapping
    public String getArticles() {
        return "getArticles";
    }
}
  • 测试
./gradlew bootrun

curl localhost:8080/articles # 返回"getArticles"

Model

vim src/main/java/com/example/SolrPractice/Article.java
package com.example.SolrPractice;

import org.apache.solr.client.solrj.beans.Field;
import org.springframework.data.annotation.Id;
import org.springframework.data.solr.core.mapping.SolrDocument;

@SolrDocument(solrCoreName = "core-practice")
public class Article {

    @Id
    @Field
    private int id;
    @Field
    private String title;
    @Field
    private String content;

    public int getId() {
        return id;
    }

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }
}

Repository

vim src/main/java/com/example/SolrPractice/ArticleRepository.java
package com.example.SolrPractice;

import org.springframework.data.solr.repository.SolrCrudRepository;

import java.util.List;

public interface ArticleRepository extends SolrCrudRepository {
    List
findAllByContentContains(String query); }

Controller

vim src/main/java/com/example/SolrPractice/ArticleController.java
package com.example.SolrPractice;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/articles")
public class ArticleController {
    @Autowired
    private ArticleRepository articleRepository;

    @GetMapping
    public List
getArticles(@RequestParam String query) { return articleRepository.findAllByContentContains(query); } }
  • 测试
curl localhost:8080/articles?query=5000 | json
curl localhost:8080/articles?query=%e6%88%aa%e8%87%b3%e7%9b%ae%e5%89%8d | json

上述query=截至目前 urlencode编解码可以参考UrlEncode编码/UrlDecode解码- 站长工具

参考

  • macOS安装Solr并索引MySQL

  • Solr【一】:初识Solr

  • Solr【二】:Spring Boot项目中使用Solr

  • spring-boot-sample-data-solr

  • Solr6.5配置中文分词IKAnalyzer和拼音分词pinyinAnalyzer (二)
