springboot检索之整合elasticsearch并使用spring-data操作

Posted 2020-11-25 西西嘛呦

各种过时，版本不兼容，只能暂时将代码放在这先做参考了。

pom.xml

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

Book.java

package com.gong.spingbootes.bean;

import org.springframework.data.elasticsearch.annotations.Document;

//这里必须指明索引名字和类型
@Document(indexName = "gong",type = "book")
public class Book {
    private Integer id;
    private String bookName;
    private String author;

    public Book(){}

    public Book(Integer id, String bookName, String author) {
        this.id = id;
        this.bookName = bookName;
        this.author = author;
    }

    @Override
    public String toString() {
        return "Book{" +
                "id=" + id +
                ", bookName=‘" + bookName + ‘‘‘ +
                ", author=‘" + author + ‘‘‘ +
                ‘}‘;
    }

    public Integer getId() {
        return id;
    }

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

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }
}

BookRepository.java

package com.gong.spingbootes.repository;

import com.gong.spingbootes.bean.Book;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;

import java.util.List;
//第一个泛型是对象类型，第二个泛型是book的主键
public interface BookRepository extends ElasticsearchRepository<Book,Integer>{
　　 //这里的名字不是随意取的，而是根据查询需求来取的，具体可参考相关文档
    public List<Book> findByBookNameLike(String bookName);
}

application.properties

spring.data.elasticsearch.cluster-name=elasticsearch
spring.data.elasticsearch.cluster-nodes=192.168.124.22
#这两玩意过时了

　　//添加索引
    @Test
