MongoDB使用mongotemplate进行模糊查询

Pattern实现

//完全匹配
Pattern pattern = Pattern.compile("^" + "张" + "$");
//右匹配
Pattern pattern = Pattern.compile("^.*" + "张" + "$");
//左匹配
Pattern pattern = Pattern.compile("^" + "张" + ".*$");
//模糊匹配
Pattern pattern = Pattern.compile("^.*" + "张" + ".*$");
Query query = Query.query(Criteria.where(name).regex(pattern));  
List<User> users = mongoTemplate.find(query, User.class, classname);

//键为”status“包含”张“的数据
Query query = new Query();
Criteria criteria = new Criteria();
criteria.and("status").regex(pattern);
query.addCriteria(criteria);
