# ConTree

>  `contree` 发音与`country`,意为：乡间美，乡间树多。

![maven中央仓库](https://img.shields.io/maven-central/v/org.openingo.kits/contree.svg)

![LTS版本](https://img.shields.io/nexus/s/org.openingo.kits/contree-parent?label=LTS%E7%89%88%E6%9C%AC&server=https%3A%2F%2Foss.sonatype.org&style=plastic)

### 特性

- 树节点添加、修改；

- 树节点级联删除、含有子节点的校验删除（有子节点时不可删除）；

- 树数据获取，指定rootNodeId，模糊nodeName，指定获取数据模式fetchType：仅第一级子节点或全部；

- 变动通知，便于其他业务处理其他事务。

### [接口文档](apis.md)

### 使用方式

- 添加依赖

```xml

    org.openingo.kits

    contree

    ${contree.version}

```

- 在启动类上加入`@EnableTree`

```java

/**

 * App

 *

 * @author Qicz

 */

@EnableExtension

@EnableTree

@SpringBootApplication

public class App {

    public static void main(String[] args) {

        SpringApplicationX.run(App.class, args);

    }

}

```

- 监听变动`implements IConTreeObserver`即可

```java

/**

 * ConTreeObserverComponent

 *

 * @author Qicz

 */

@Component

@Slf4j

public class ConTreeObserverComponent implements IConTreeObserver {

    /**

     * 删除处理响应

     * 

     * 1. 这处理与树删除在同一个事务中；

     * 2. 业务端收到onTreeNodeDelete消息后，处理完成业务逻辑；

     * 3. 以上都无异常，则事务正常提交。

     * 

     *

     * @param treeCode 树编码

     * @param nodes    删除的node信息

     */

    @Override

    public void onTreeNodeDelete(String treeCode, List nodes) {

        log.info("😃 treeCode = {}, nodes = {}", treeCode, nodes);

    }

}

```
