<mongo:repositories base-package="com.domain.*.repo" repository-impl-postfix="CustomImpl" 
    factory-class="com.domain.commonrepo.CommonMongoRepoFactoryBean"/>

<bean id="mappingContext" class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />

<mongo:mapping-converter mapping-context-ref="mappingContext">
    <mongo:custom-converters base-package="com.domain.mongo.converter" />
</mongo:mapping-converter>

<bean id="entityInformationCreator" class="org.springframework.data.mongodb.repository.support.DefaultEntityInformationCreator">
    <constructor-arg name="mappingContext" ref="mappingContext" />
</bean>

FactoryBean

    @NoRepositoryBean
    public class CommonMongoRepoFactoryBean<T extends MongoRepository<?,?>, ID extends        
    Serializable> extends MongoRepositoryFactoryBean{

@Autowired
private static MongoTemplate mongoTemplate;

protected MongoRepositoryFactory getRepositoryFactory(Class<T> clazz) {
    return new CommonMongoRepoFactory(clazz);
}

private static class CommonMongoRepoFactory extends MongoRepositoryFactory {
    private Class clazz;
