一、案例pom依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <relativePath /> <!-- lookup parent from repository -->
    </parent>
    <dependencies>

        <!-- springboot整合freemarker -->

            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
    </dependencies>
</project>

二、Elasticsearch生成案例数据
在kibana中执行下面的脚本：

PUT /clouddisk

POST /clouddisk/_mapping/disk
{
        "disk": {
        "properties": {
          "baiduaddres": {
            "type": "keyword"
          },
          "browsetimes": {
            "type": "long"
          },
          "collectiontime": {
            "type": "date"
          },
          "describe": {
            "type": "text",
            "analyzer": "ik_smart"
          },
          "filesize": {
            "type": "float"
          },
          "name": {
            "type": "text",
            "analyzer": "ik_smart"
          },
          "sharpeople": {
            "type": "keyword"
          },
          "shartime": {
            "type": "date"
          },
          "source": {
            "type": "keyword"
          }
        }
      }
  
}

POST /clouddisk/disk
{
  "name":"2020世上最全SpringCloud",
  "source":"百度云盘",
  "describe":"该资料由独角兽百度收集",
  "shartime":"2020-05-05",
  "browsetimes":100000,
  "filesize":3.65,
  "sharpeople":"独角兽",
  "collectiontime": "2020-05-05",
  "baiduaddres":"https:pan.baidu.com"
}

POST /clouddisk/disk
{
  "name":"腾讯课堂SpringCloud和SpringBoot",
  "source":"百度云盘",
  "describe":"该资料由腾讯课堂出品",
  "shartime":"2020-05-05",
  "browsetimes":100000,
  "filesize":3.65,
  "sharpeople":"独角兽",
  "collectiontime": "2020-05-05",
  "baiduaddres":"https:pan.baidu.com"
}

POST /clouddisk/disk
{
  "name":"腾讯课堂SpringBoot整合SSM案例",
  "source":"百度云盘",
  "describe":"该资料由腾讯课堂出品",
  "shartime":"2020-05-05",
  "browsetimes":100000,
  "filesize":3.65,
  "sharpeople":"独角兽",
  "collectiontime": "2020-05-05",
  "baiduaddres":"https:pan.baidu.com"
}


POST /clouddisk/disk
{
  "name":"网易课堂SpringBoot整合SSM案例",
  "source":"百度云盘",
  "describe":"该资料由网易课堂出品",
  "shartime":"2020-05-05",
  "browsetimes":100000,
  "filesize":3.65,
  "sharpeople":"独角兽",
  "collectiontime": "2020-05-05",
  "baiduaddres":"https:pan.baidu.com"
}

POST /clouddisk/disk
{
  "name":"阿里巴巴课堂SpringBoot整合SSM案例",
  "source":"百度云盘",
  "describe":"该资料由阿里巴巴课堂出品",
  "shartime":"2020-05-05",
  "browsetimes":100000,
  "filesize":3.65,
  "sharpeople":"独角兽",
  "collectiontime": "2020-05-05",
  "baiduaddres":"https:pan.baidu.com"
}

三、案例Demo代码
1）、全局配置文件

spring:
  data:
    elasticsearch:
    ####集群名称
     cluster-name: myes
    ####地址 
     cluster-nodes: 192.168.43.104:9300
  freemarker:
    # 设置模板后缀名
    suffix: .ftl
    # 设置文档类型
    content-type: text/html
    # 设置页面编码格式
    charset: UTF-8
    # 设置页面缓存
    cache: false
    # 设置ftl文件路径
    template-loader-path:
      - classpath:/templates
  # 设置静态文件路径，js,css等
  mvc:
    static-path-pattern: /static/**

2）、实体类层

@Data
@Document(indexName = "clouddisk", type = "disk")
public class CloudDiskEntity {
    
    @Id
    private String id;
    // 名称
    private String name;
    // 来源
    private String source;
    // 描述
    private String describe;
    // 分享时间
    private Date shartime;
    // 浏览次数
    private Long browsetimes;
    // 文件大小
    private Double filesize;
    // 分享人
    private String sharpeople;
    // 收录时间
    private String collectiontime;
    // 地址
    private String baiduaddres;

}

3）、Repository层

public interface CloudDiskDao extends ElasticsearchRepository<CloudDiskEntity, String> {

}

4）、控制层

@Controller
public class SearchController {
    @Autowired
    private CloudDiskDao cloudDiskDao;

    @RequestMapping("/search")
    public String search(String keyword,
                         String describe,
                         @PageableDefault(page = 0, value = 5) Pageable pageable,
                         HttpServletRequest req) {
        //开始时间
        long startTime = System.currentTimeMillis();
        // 创建查询对象
        BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
        if (!StringUtils.isEmpty(keyword)) {
            // 模糊查询 一定要ik中文
            MatchQueryBuilder matchQuery = QueryBuilders.matchQuery("name", keyword);
            boolQuery.must(matchQuery);
        }
        if (!StringUtils.isEmpty(describe)) {
            MatchQueryBuilder matchQuery = QueryBuilders.matchQuery("describe", describe);
            boolQuery.must(matchQuery);
        }
        // 调用查询接口
        Page<CloudDiskEntity> page = cloudDiskDao.search(boolQuery, pageable);
        req.setAttribute("page", page);
        // 记录总数
        req.setAttribute("total", page.getTotalElements());
        req.setAttribute("keyword", keyword);
        // 计算分页总数
        int totalPage = (int) ((page.getTotalElements() - 1) / pageable.getPageSize() + 1);

        // 分页总数
        req.setAttribute("totalPage", totalPage);
        Long emdTime = System.currentTimeMillis();
        req.setAttribute("time", emdTime - startTime);
        return "search";
    }
}

5）、启动类

@SpringBootApplication
@EnableElasticsearchRepositories(basePackages = "com.zhq.repository")
public class AppElasticsearch {
    public static void main(String[] args) {
        SpringApplication.run(AppElasticsearch.class,args);
    }
}

6）、页面实现
