# spring-data-hugegraph

#### 介绍
图数据库hugegraph相应的spring data组件，可通过repository访问后端hugraph图数据库

#### 软件架构
软件架构说明


#### 编译安装

```
$ mvn clean install -Dcheckstyle.skip=true -DskipTests
```

#### 使用说明

定义顶点（vertex）的entity

```java
import com.baidu.spring.data.hugegraph.annotation.Index;
import com.baidu.spring.data.hugegraph.annotation.Vertex;
import com.baidu.spring.data.hugegraph.schema.IdStrategy;
import com.baidu.spring.data.hugegraph.schema.IndexType;
import lombok.Data;
import lombok.AllArgsConstructor;
import lombok.NoArgsConstructor;

@Vertex(label = "Netware", idStrategy = IdStrategy.CUSTOMIZE_STRING)
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Netware {

    @Id
    private String gid;

    // 设备管理ip
    @Index(type = IndexType.SECONDARY)
    @IsInetAddress
    private String mgmtIp;

    // 设备名
    @Index(type = IndexType.SECONDARY)
    private String hostname;
    
    private String role;

}

```
定义边（edge）的entity

```java
import com.baidu.spring.data.hugegraph.annotation.Edge;
import com.baidu.spring.data.hugegraph.annotation.EdgeHead;
import com.baidu.spring.data.hugegraph.annotation.EdgeTail;
import com.baidu.spring.data.hugegraph.schema.Multiplicity;
import com.baidu.spring.data.hugegraph.annotation.SortKey;
import lombok.Data;
import lombok.AllArgsConstructor;
import lombok.NoArgsConstructor;


@Edge(label = "L2_LINK", aliasLabel = "layer2Link", multiplicity = Multiplicity.MULTI)
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Layer2Link {

    @Id
    private String gid;

    @EdgeHead
    private transient Netware head;

    @EdgeTail
    private transient TailT tail;

    @SortKey
    private String linkid;

}
```

定义相应的repositry
```java

@Repository
public interface NetwareRepository extends HugeRepository<Netware, String> {

    @Query("g.V(':mgmtIp')")
    List<Netware> findByMgmtIp(@Param("mgmtIp") final String mgmtIp);

}

@Repository
public interface Layer2LinkRepository extends HugeRepository<Layer2Link, String> {

    @Query(":script")
    List<Layer2Link> findByScript(@Param("script") final String script);

    @Query("g.V(':locMgmtIp').bothE('L2_LINK').where(otherV().has('Netware', 'role', ':remRole'))")
    List<Layer2Link> findAllByLocMgmtIpAndRemRole(@Param("locMgmtIp") String locMgmtIp,
                                                  @Param("remRole") String remRole);
}
```
