SpringBoot整合ElasticSearch

Posted 2023-03-02 陈一一同学

首先springBoot 项目的pom文件中引入jar包

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-data-elasticsearch</artifactId>

</dependency>

yml文件配置

# Spring配置

spring:

elasticsearch:

uris: 127.0.0.1:9200

我这里是使用继承ElasticsearchRepository来做简单的增删查的

建一个类ArticleRepository继承ElasticsearchRepository

@Repository
public interface ArticleRepository extends ElasticsearchRepository<EsArticleDto, Long> 

    List<EsArticleDto> findByTitle(String title,String lang);
    List<EsArticleDto> findByTitleEnglish(String titleEnglish,String lang);
    Page<EsArticleDto> findByTitleAndLangAndCreateDateIntBetween(String title, String lang,Integer from,Integer to, Pageable pageable);
    List<EsArticleDto> findByDetailhtml(String content,String lang);
    List<EsArticleDto> findByDetailHtmlEnglish(String contentEnglish,String lang);

    List<EsArticleDto> findByTitleOrDetailHtmlAndLang(String title, String detailHtml, String lang);
    List<EsArticleDto> findByLangAndCreateDateIntBetween(String lang,Integer from,Integer to,Pageable pageable);

建一个servi类

public interface ArticleService 
    EsArticleDto save(EsArticleDto articleDto);
    void delete(EsArticleDto articleDto);
    Iterable<EsArticleDto> getAll();
    List<EsArticleDto> findByTitle(String title, String lang);
    List<EsArticleDto> findByTitleEnglish(String titleEnglish,String lang);
    Page<EsArticleDto> findByTitleAndLangAndCreateDateIntBetween(String title, String lang,Integer from,Integer to, Pageable pageable);
    List<EsArticleDto> findByTitleOrDetailHtmlAndLang(String title, String detailHtml, String lang);
    List<EsArticleDto> findByDetailHtml(String content,String lang);
    List<EsArticleDto> findByDetailHtmlEnglish(String contentEnglish,String lang);
    List<EsArticleDto> findByLangAndCreateDateIntBetween(String lang,Integer from,Integer to,Pageable pageable);

serviceimpl

@Service
public class ArticleServiceImpl implements ArticleService 

    @Autowired
    private ArticleRepository articleRepository;


    @Override
    public EsArticleDto save(EsArticleDto articleDto) 
        return articleRepository.save(articleDto);
    

    @Override
    public void delete(EsArticleDto articleDto) 
        articleRepository.delete(articleDto);
    

    @Override
    public Iterable<EsArticleDto> getAll() 
        return articleRepository.findAll();
    

    @Override
    public List<EsArticleDto> findByTitle(String title, String lang) 
        return articleRepository.findByTitle(title,lang);
    

    @Override
    public List<EsArticleDto> findByTitleEnglish(String titleEnglish, String lang) 


        return articleRepository.findByTitleEnglish(titleEnglish,lang);
    
    @Override
    public Page<EsArticleDto> findByTitleAndLangAndCreateDateIntBetween(String title, String lang,Integer from,Integer to, Pageable pageable) 
        return articleRepository.findByTitleAndLangAndCreateDateIntBetween(title,lang,from,to,pageable);
    
    @Override
    public List<EsArticleDto> findByTitleOrDetailHtmlAndLang(String title, String detailHtml, String lang) 
        return articleRepository.findByTitleOrDetailHtmlAndLang(title,detailHtml,lang);
    
    @Override
    public List<EsArticleDto> findByDetailHtml(String content,String lang) 
        return articleRepository.findByDetailHtml(content,lang);
    

    @Override
    public List<EsArticleDto> findByDetailHtmlEnglish(String contentEnglish, String lang) 
        return articleRepository.findByDetailHtmlEnglish(contentEnglish,lang);
    

    @Override
    public List<EsArticleDto> findByLangAndCreateDateIntBetween(String lang, Integer from, Integer to, Pageable pageable) 
        return articleRepository.findByLangAndCreateDateIntBetween(lang,from,to,pageable);
    

在controller里面我这里是根据title搜索的，这里通过那个字段搜索直接加就行了

   List<EsArticleDto> title = articleService.findByTitle("*" + article.getTitle() + "*", "*" + article.getTitle() + "*");
