实现将redis中的所有数据备份到数据库表中

实现将redis中的所有数据备份到数据库表中

/**
     * 将redis中的数据同步到mysql中

    @Override
    public void  saveMysqlForRedis(){
        Jedis jedis = new Jedis("127.0.0.1", 6379);
        //System.out.println(jedis.ping());
        Set keys = jedis.keys("*");//列出所有的key
        Iterator t1 = keys.iterator();
        while (t1.hasNext()){
            Object obj1 = t1.next();
            saveRedisObject(jedis,obj1+"","127.0.0.1","6379");
        }

    }
    //存储单个对象
    public  void saveRedisObject(final Jedis jedis,final String rediskey,final String macIp,final String port ){
        String redisType = jedis.type(rediskey);//返回值的类型
        RedisTable redisTable = new RedisTable();
        redisTable.setRediskey(rediskey);
        redisTable.setRedistype(redisType+"/");
        //set集合
        if("set".equalsIgnoreCase(redisType)){
            Set<String> setStrings = jedis.smembers(rediskey);
            if(null!=setStrings && !setStrings.isEmpty()){
                Iterator setIterator = setStrings.iterator();

                    redisTable.setRedisvalue(obj1+"");
                    redisTableService.insert(redisTable);//save
                }
            }
        }
        //hash
        else if ("hash".equalsIgnoreCase(redisType)) {
            Set<String> hashSet = jedis.hkeys(rediskey);

                    String objectName = setIterator.next()+"";
                    redisTable.setRedisvalue(jedis.hget(rediskey,objectName));
                    redisTableService.insert(redisTable);//save
                }
            }
        }else if("string".equalsIgnoreCase(redisType)){
            redisTable.setRedisvalue((jedis.get(rediskey)));
            redisTableService.insert(redisTable);//save
        }
    }
    ...同样的，还有redis的其他数据类型，如下图：

注意：
1.需要考虑redis和mysql数据的一致性；
2.考虑redis数据导入的数据的重复性问题。
