application.yml

easy-es:
  enable: true #默认为true,若为false则认为不启用本框架
  banner: false # 默认为true 打印banner 若您不期望打印banner,可配置为false
  address : 127.0.0.1:9200 # es的连接地址,必须含端口 若为集群,则可以用逗号隔开 例如:127.0.0.1:9200,127.0.0.2:9200
  username: elastic #若无 则可省略此行配置
  password: WG7WVmuNMtM4GwNYkyWH #若无 则可省略此行配置
  # 请求通信超时时间 单位:ms 在平滑模式下,由于要迁移数据,用户可根据数据量大小调整此参数值大小,否则请求容易超时导致索引托管失败,建议您尽量给大不给小
  socketTimeout: 5000
  global-config:
    # 项目是否分布式环境部署,默认为true, 如果是单机运行可填false,将不加分布式锁,效率更高.
    distributed: false

}

DocumentMapper (官方建议：Easy-Es的Mapper和MyBatis-Plus分开存放)

在这里插入图片描述
和MyBatis-Plus差不多都是继承mapper，但是Easy-Es不需要继承Service和ServiceImpl

import cn.easyes.core.conditions.interfaces.BaseEsMapper;
import org.springframework.stereotype.Repository;

@Repository
public interface DocumentMapper extends BaseEsMapper<Document> {

}

DocumentService

人家没有帮我们写，那我们就自己写

public interface DocumentService {

    Integer insert(Document document);

    Document selectById(String id);

    Integer updateById(Document document);

    Integer deleteById(String id);

    List<Document> selectList();

    EsPageInfo<Document> pageQuery(Integer pageIndex, Integer pageSize);

    Integer deleteBatchIds(List<String> ids);
}

DocumentServiceImpl

@Service
public class DocumentServiceImpl implements DocumentService {
    @Resource
    private DocumentMapper documentMapper;

    @Override
    public Integer insert(Document document) {
        return this.documentMapper.insert(document);
    }

    @Override
    public Document selectById(String id) {
        return this.documentMapper.selectById(id);
    }

    @Override
    public Integer updateById(Document document) {
        return this.documentMapper.updateById(document);
    }

    @Override
    public Integer deleteById(String id) {
        return this.documentMapper.deleteById(id);
    }

    @Override
    public List<Document> selectList() {
        LambdaEsQueryWrapper<Document> leqw = new LambdaEsQueryWrapper<>();
        return this.documentMapper.selectList(leqw);
    }

    @Override
    public EsPageInfo<Document> pageQuery(Integer pageIndex, Integer pageSize) {
        LambdaEsQueryWrapper<Document> leqw = new LambdaEsQueryWrapper<>();
        return this.documentMapper.pageQuery(leqw, pageIndex, pageSize);
    }

    @Override
    public Integer deleteBatchIds(List<String> ids) {
        return this.documentMapper.deleteBatchIds(ids);
    }

}

DocumentController

@RestController
@RequestMapping("document")
public class DocumentController {

    @Resource
    private DocumentService documentService;

    /**
     * 测试程序是否正常运行
     */
    @GetMapping("hello")
    public String hello() {
        return "hello world!";
    }

    /**
     * 新增
     */
    @PostMapping
    public Integer insert(@RequestBody Document document) {
        return this.documentService.insert(document);
    }

    /**
     * 查询
     */
    @GetMapping("{id}")
    public Document selectById(@PathVariable String id) {
        return this.documentService.selectById(id);
    }

    /**
     * 更新
     */
    @PutMapping
    public Integer updateById(@RequestBody Document document) {
        return this.documentService.updateById(document);
    }

    /**
     * 删除
     */
    @DeleteMapping("{id}")
    public Integer deleteById(@PathVariable String id) {
        return this.documentService.deleteById(id);
    }

    /**
     * 查询列表
     */
    @GetMapping
    public List<Document> selectList() {
        return this.documentService.selectList();
    }

    /**
     * 分页查询
     */
    @GetMapping("paging")
    public EsPageInfo<Document> pageQuery(@RequestParam(value = "pageIndex", defaultValue = "1") Integer pageIndex,
                                          @RequestParam(value = "pageSize", defaultValue = "1") Integer pageSize) {
        return this.documentService.pageQuery(pageIndex, pageSize);
    }

    /**
     * 批量删除
     */
    @DeleteMapping
    public Integer deleteBatchIds(@RequestBody List<String> ids) {
        return this.documentService.deleteBatchIds(ids);
    }

}

Application启动类加上扫描EsMapper接口注解

@SpringBootApplication
@EsMapperScan("com.aoxqwl.eedemo.mapper.ee") //还是那句话，建议和MyBatis-Plus的mapper分开存放
public class EedemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(EedemoApplication.class, args);
    }
}

结束语

整体下来和MyBatis-Plus是非常贴合的，如果你的项目中使用到了MyBatis-Plus，那么首选是Easy-Es！同样的Easy-Es目前占卜支持SpringBoot3.X，也是个美中不足吧。但是我想目前大家的生产环境都没上SpringBoot3.X吧！接口那些就自己用Postman测一下吧，都是没有问题的。
