Mongodb进行模糊查询教程

使用RockMongo客户端工具进行模糊查询

{"content":"$regex": "123456"}

其他情况模糊查询

查询包含XXX

{name:/xxx/}

查询以XXX开头

{name:/^xxx/}

查询以XXX结尾

{name:/xxx^/}

查询忽略大小写

{name:/xxx/i}

Spring中不区分大小写的模糊查询

//完全匹配
Pattern pattern = Pattern.compile("^王$", Pattern.CASE_INSENSITIVE);
//右匹配
Pattern pattern = Pattern.compile("^.*王$", Pattern.CASE_INSENSITIVE);
//左匹配
Pattern pattern = Pattern.compile("^王.*$", Pattern.CASE_INSENSITIVE);
//模糊匹配
Pattern pattern = Pattern.compile("^.*王.*$", Pattern.CASE_INSENSITIVE);
Query query = Query.query(Criteria.where(fieldName).regex(pattern));  
        List users = mongoTemplate.find(query, SimpleUserInfo.class, classname);
        return users;
