flowable给所有表加注释

你可以使用Flowable的元数据管理功能来给所有的表添加注释。首先,你需要创建一个实现了`MetadataEventListener`接口的类,用于监听数据库元数据的变化。在该类中,你可以实现`onSchemaCreated`方法,在该方法中获取到所有的表并为它们添加注释。
下面是一个示例代码:
```java
import org.flowable.common.engine.api.delegate.event.FlowableEngineEntityEvent;
import org.flowable.common.engine.api.delegate.event.FlowableEntityEvent;
import org.flowable.common.engine.api.delegate.event.FlowableEventListener;
import org.flowable.common.engine.api.delegate.event.FlowableEventType;
import org.flowable.engine.impl.persistence.entity.TableDataManager;
public class TableCommentEventListener implements FlowableEventListener {
private TableDataManager tableDataManager;
public void setTableDataManager(TableDataManager tableDataManager) {
this.tableDataManager = tableDataManager; }
@Override
public void onEvent(FlowableEvent event) {
FlowableEventType eventType = ((FlowableEntityEvent) event).getType();
if (eventType == FlowableEngineEventType.ENTITY_CREATED) {
FlowableEngineEntityEvent engineEntityEvent = (FlowableEngineEntityEvent) event;
if (engineEntityEvent.getEntity() instanceof TableEntity) {
TableEntity tableEntity = (TableEntity) engineEntityEvent.getEntity();
tableEntity.setComment("Your table comment");
tableDataManager.updateTable(tableEntity);
}
}
}
@Override
public boolean isFailOnException() {
return false;
}
}
```
在你的Flowable应用中,配置该监听器:
```java
ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResourceDefault();
configuration.setEventListeners(Arrays.asList(new TableCommentEventListener()));
```
请注意,上述代码只是一个示例,你需要根据具体的需求进行修改和适配。另外,你可能需要在Flowable的配置文件中指定该监听器。
