MongoTemplate 移除 _class 字段
@Configuration
public class ApplicationReadyListener implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
MongoTemplate mongoTemplate;
@Override
public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
MongoConverter converter = mongoTemplate.getConverter();
if (converter.getTypeMapper().isTypeKey("_class")) {
((MappingMongoConverter) converter).setTypeMapper(new DefaultMongoTypeMapper(null));
}
}
}
