springboot整合es详细步骤

好的，下面是springboot整合es的详细步骤：

1. 在pom.xml文件中添加elasticsearch和spring-data-elasticsearch依赖。

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>版本号</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>版本号</version>
</dependency>

2. 在application.yml文件中添加ES配置信息。

spring:
  elasticsearch:
    rest:
      uris: http://localhost:9200
      username: 用户名
      password: 密码

3. 创建一个ES实体类，并使用注解来定义索引名、类型名和字段属性等。

@Document(indexName = "blog", type = "article")
public class Article {

    @Id
    private Long id;

    @Field(type = FieldType.Text, analyzer = "ik_max_word")
    private String title;

    @Field(type = FieldType.Text, analyzer = "ik_max_word")
    private String content;

    @Field(type = FieldType.Keyword)
    private String author;

    @Field(type = FieldType.Date)
    private Date createTime;

    // getter和setter方法省略
}

4. 创建一个ES的Repository接口，继承ElasticsearchRepository，并定义一些自定义查询方法。

public interface ArticleRepository extends ElasticsearchRepository<Article, Long> {

    List<Article> findByTitle(String title);

    List<Article> findByContent(String content);

    List<Article> findByAuthor(String author);

    List<Article> findByCreateTimeBetween(Date begin, Date end);
}

5. 在Service中调用Repository的方法，实现对ES的CRUD操作。

@Service
public class ArticleService {

    @Autowired
    private ArticleRepository articleRepository;

    public void save(Article article) {
        articleRepository.save(article);
    }

    public void deleteById(Long id) {
        articleRepository.deleteById(id);
    }

    public Optional<Article> findById(Long id) {
        return articleRepository.findById(id);
    }

    public List<Article> findByTitle(String title) {
        return articleRepository.findByTitle(title);
    }

    public List<Article> findByContent(String content) {
        return articleRepository.findByContent(content);
    }

    public List<Article> findByAuthor(String author) {
        return articleRepository.findByAuthor(author);
    }

    public List<Article> findByCreateTimeBetween(Date begin, Date end) {
        return articleRepository.findByCreateTimeBetween(begin, end);
    }
}

6. 测试ES的CRUD操作。

@RunWith(SpringRunner.class)
@SpringBootTest
public class ArticleServiceTest {

    @Autowired
    private ArticleService articleService;

    @Test
    public void save() {
        Article article = new Article();
        article.setId(1L);
        article.setTitle("Spring Boot 整合 Elasticsearch");
        article.setContent("Spring Boot 整合 Elasticsearch 详细步骤");
        article.setAuthor("张三");
        article.setCreateTime(new Date());
        articleService.save(article);
    }

    @Test
    public void deleteById() {
        articleService.deleteById(1L);
    }

    @Test
    public void findById() {
        Optional<Article> optional = articleService.findById(1L);
        if (optional.isPresent()) {
            System.out.println(optional.get().getTitle());
        }
    }

    @Test
    public void findByTitle() {
        List<Article> list = articleService.findByTitle("Spring Boot");
        for (Article article : list) {
            System.out.println(article.getTitle());
        }
    }

    @Test
    public void findByContent() {
        List<Article> list = articleService.findByContent("详细步骤");
        for (Article article : list) {
            System.out.println(article.getTitle());
        }
    }

    @Test
    public void findByAuthor() {
        List<Article> list = articleService.findByAuthor("张三");
        for (Article article : list) {
            System.out.println(article.getTitle());
        }
    }

    @Test
    public void findByCreateTimeBetween() {
        Date begin = new Date(0L);
        Date end = new Date();
        List<Article> list = articleService.findByCreateTimeBetween(begin, end);
        for (Article article : list) {
            System.out.println(article.getTitle());
        }
    }
}

以上就是springboot整合es的详细步骤，希望对你有所帮助。
