`ebatis`是一个声明式`Elasticsearch ORM`框架。只需要定义接口，便可轻松访问`Elasticsearch`。`ebatis`优雅地帮你隔离业务对`Elasticserach`底层驱动接口的直接调用，你不再需要自己手动去构建繁琐`DSL`
语句。同时，当升级`Elastisearch`版本的时候，业务可以完全不用关心底层接口的变动，平滑升级。  
目前，支持`Elastisearch` `6.5.1`与`7.5.1`版本。

# ebatis现状

`ebatis`已经在满帮业务系统上稳定运行近一年，承载着每日近十亿次搜索服务。

# QUICK START
`POM`依赖（目前也支持`6.5.1.2.RELEASE`）
```xml
<dependency>
     <groupId>io.manbang</groupId>
     <artifactId>ebatis-core</artifactId>
     <version>7.5.1.4.RELEASE</version>
</dependency>
```
创建集群连接如下:
```java
@AutoService(ClusterRouterProvider.class)
public class SampleClusterRouterProvider implements ClusterRouterProvider {
    public static final String SAMPLE_CLUSTER_NAME = "sampleCluster";
 
    @Override
    public ClusterRouter getClusterRouter(String name) {
        if (SAMPLE_CLUSTER_NAME.equalsIgnoreCase(name)) {
            Cluster cluster = Cluster.simple("127.0.0.1", 9200, Credentials.basic("admin", "123456"));
            return ClusterRouter.single(cluster);
        } else {
            return null;
        }
    }
}
```
定义`POJO`对象如下:
```java
@Data
public class RecentOrder {
    private Long cargoId;
    private String driverUserName;
    private String loadAddress;
    private Boolean searchable;
    private Integer companyId;
}

@Data
public class RecentOrderCondition {
    private Boolean searchable;

    private String driverUserName;
}
```
定义`Mapper`接口
```java
@Mapper(indices = "recent_order_index")
public interface RecentOrderRepository {
    @Search
    List<RecentOrder> search(RecentOrderCondition condition);
}
```
测试接口如下:
```java
@Slf4j
public class OrderRepositoryTest {
 
    @Test
    public void search() {
        // 组装查询条件
        RecentOrderCondition condition = new RecentOrderCondition();
        condition.setSearchable(Boolean.TRUE);
        condition.setDriverUserName("张三");
 
        // 映射接口
        RecentOrderRepository repository = MapperProxyFactory.getMapperProxy(RecentOrderRepository.class, SampleClusterRouterProvider.SAMPLE_CLUSTER_NAME);
 
        // 搜索货源
        List<RecentOrder> orders = repository.search(condition);
 
        // 断言
        Assert.assertEquals(3, orders.size());
 
        // 打印输出
        orders.forEach(order -> log.info("{}", order));
    }
}
```
搜索得`DSL`语句如下:
```json
{
  "query" : {
    "bool" : {
      "must" : [ {
        "term" : {
          "searchable" : {
            "value" : true,
            "boost" : 1.0
          }
        }
      }, {
        "term" : {
          "driverUserName" : {
            "value" : "张三",
            "boost" : 1.0
          }
        }
      } ],
      "adjust_pure_negative" : true,
      "boost" : 1.0
    }
  },
  "_source" : {
    "includes" : [ "cargoId", "driverUserName", "loadAddress", "searchable", "companyId" ],
    "excludes" : [ ]
  }
}
```
`ebatis`版本使用`xx.xx.xx.xx.RELEASE`表示，前三位代表`Elasticsearch`适配集群的驱动版本，后一位代表`ebatis`在此版本上的迭代。例如`7.5.1.3.RELEASE`表示`ebatis`在`Elasticsearch 7.5.1`版本上迭代的第三次版本。
