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));
}
}
}
MongoTemplate針對多條件查詢以及復雜查詢基本示例
https://blog.csdn.net/junqilong/article/details/79379399
查詢或語句：a || b
-
Criteria criteria = new Criteria();
-
criteria.orOperator(Criteria. where("key1").is("0"),Criteria.where("key1").is(null));
查詢且語句：a && b
Criteria criteria = new Criteria();
criteria.and(“key1”).is(false);
criteria.and(“key2”).is(type);
Query query = new Query(criteria);
long totalCount = this.mongoTemplate.count(query, Xxx.class);
