Remove _class from Mongo documents - Spring Data MongoDB

Spring Data MongoDB adds _class in the mongo documents to handle polymorphic behavior of java inheritance. If you want to remove _class just drop following Config class in your code.

package com.waseem.config;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.data.mongodb.MongoDbFactory;

import org.springframework.data.mongodb.core.convert.DbRefResolver;

import org.springframework.data.mongodb.core.convert.DefaultDbRefResolver;

import org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper;

import org.springframework.data.mongodb.core.convert.MappingMongoConverter;

import org.springframework.data.mongodb.core.mapping.MongoMappingContext;

@Configuration

public class MongoConfig {

@Autowired MongoDbFactory mongoDbFactory;

@Autowired MongoMappingContext mongoMappingContext;

@Bean

public MappingMongoConverter mappingMongoConverter() {

DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory);

MappingMongoConverter converter = new MappingMongoConverter(dbRefResolver, mongoMappingContext);

converter.setTypeMapper(new DefaultMongoTypeMapper(null));

return converter;

}

}
