### 一、引入相关Jar ###

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

### 二、配置相关信息 ###

spring.data.elasticsearch.cluster-name=elasticsearch
    spring.data.elasticsearch.cluster-nodes=192.168.43.118:9300

### 三、编写测试Demo  ###

1）、通过编写一个ElasticsearchRepository的子接口来操作ES，其他方式可以参考官方文档

@Document(indexName = "zhq",type = "book")
    public class Book {
        private Integer id;
        private  String bookName;
        private String 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;
        }
    
        @Override
        public String toString() {
            return "Book{" +
                    "id=" + id +
                    ", bookName='" + bookName + '\'' +
                    ", author='" + author + '\'' +
                    '}';
        }
    }

2）、编写单元测试

@Autowired
        BookRepository bookRepository;
        @Test
        public void  addIndex(){
            Book book=new Book();
            book.setId(1);
            book.setBookName("Java入门到放弃");
            book.setAuthor("张三");
            bookRepository.index(book);
        }
        @Test
        public void getBookByBookName(){
            List<Book> books = bookRepository.findByBookNameLike("入门");
            for (Book book : books) {
                System.out.println(book);
            }
        }
