[Spring] [MongoDB] MongoDB Collection Event Listener

Event Listeners:

• onBeforeConvert(E document)
• onAfterConvert(DbObject dbo, E document)
• onBeforeSave(E document)
• onAfterSave( E collection, DbObject dbo)
• ...

How to Use:

Step 1: Write Java class

package com.tsp.event; import javax.annotation.Resource; import org.springframework.data.mongodb.core.mapping.event. AbstractMongoEventListener; // line broken for rendering import com.mongodb.DBObject; /** * @author siva mondi * */ public class UserEventListener extends AbstractMongoEventListener<User> {     @Override     public void onBeforeConvert(User user) {     }     @Override     public void onBeforeSave(User user, DBObject dbo) {     }     @Override     public void onAfterSave(User user, DBObject dbo) {     }     @Override     public void onAfterLoad(DBObject dbo) {     }     @Override     public void onAfterConvert(DBObject dbo, User user) {     } }

Step 2: Register Event Listener in Spring XML

<!-- All The Event Listeners -->    <bean class="com.tsp.event.UserEventListener" />
