redis工具类设计之回调函数的使用_rediscallback

前言

我们平时在项目中手写共同工具类的时候, 对于好多异常的处理很是头疼, 对于各种连接, 各种io的开启关闭控制都是一个头大的事情, 放在具体使用阶段进行处理又怕别人使用的时候忘记关闭. 这个时候回调函数的作用就体现出来了.

代码

回调函数需要一个接口, 当然写到类中也是没有问题的:

public class RedisTemplate {
    private Jedis jedis;

    public RedisTemplate(Jedis jedis) {
        this.jedis = jedis;
    }

    public <T> T execute(RedisCallback<T> callback) throws Exception {
        try {
            return callback.handle(jedis);
        }
        catch (Exception e) {
            throw e;
        }
        finally {
            returnResource(jedis);
        }
    }

    private void returnResource(Jedis jedis) {
        if (jedis != null) {
            jedis.close();
        }
    }

    public interface RedisCallback<T> {
        public T handle(Jedis jedis);
    }
}

如下是一个简化版的redis工具类, 对连接使用后进行了关闭:
这里没有加入bitmap的代码, 读者根据需要可自行加入. 另外添加了一些用于页面操作redis的方法, 能更灵活的控制redis中的数据, 不用访问客户端, 也会更直观的观察到库中数据, 如果库中数据量很大, 建议对redis进行分库, 本工具类对管理人员开放了getPrex+*的模糊查询方法, 会对大数据量的redis库产生一定压力. 慎用

public class RedisUtil {

            config.setMaxIdle(Integer.parseInt(PROPS.getValue("redis.maxIdle"))); // 控制一个Pool最多有多少个状态为idle(空闲的)jedis实例,默认值也是8
