Spring集成redis（pipeline方式）

1.maven添加spring、redis、log4j依赖

properties设置

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <spring.version>4.3.0.RELEASE</spring.version>
        <jedis.version>2.1.0</jedis.version>
        <springdateredis.version>1.0.2.RELEASE</springdateredis.version>        
    </properties>

相关dependency

        <!-- spring 依赖 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <!-- springredis -->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>${springdateredis.version}</version>
        </dependency>

        <!-- redis 依赖 -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>${jedis.version}</version>
        </dependency>

        <!-- log4j日志 -->
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.7</version>
        </dependency>

2.新建dao接口

package com.lgd.ssh.spider.Dao;

import java.util.List;
import java.util.Map;

public interface RedisDao {

    /**
     * 向redis添加数据
     * 
     * @param addMap<key,
     *            value>
     */
    public void add(Map<String, String> addMap);

    /**
     * 删除redis数据
     * 
     * @param deleteList<key>
     */
    public void delete(List<String> deleteList);

    /**
     * 更新redis数据
     * 
     * @param updateMap<key,
     *            value>
     */
    public void update(Map<String, String> updateMap);

    /**
     * 查询
     * 
     * @param queryList
     */
    public Map<String, String> query(List<String> queryList);
}

3.具体实现
redisbase类

package com.lgd.ssh.spider.Dao.Spi;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.Pipeline;

/**
 * redis基类
 * @author lgd
 *
 */
public class RedisBaseDao {

    private static JedisPool jedisPool;

    public static JedisPool getJedisPool() {
        return jedisPool;
    }

    public static void setJedisPool(JedisPool jedisPool) {
        RedisBaseDao.jedisPool = jedisPool;
    }

    private Jedis getJedis() {
        return jedisPool.getResource();
    }

    private Jedis getJedisClient() {
        return getJedis();
    }

    private Pipeline getPipeline() {
        Jedis jedis = getJedisClient();
        return jedis.pipelined();
    }

    public <T> T RedisExecute(RedisExecute<T> redisExcute){

        Pipeline pipeline = getPipeline();
        return redisExcute.Execute(pipeline);       
    }

}

RedisExecute接口，其实现类实现具体功能

package com.lgd.ssh.spider.Dao.Spi;

import redis.clients.jedis.Pipeline;

public interface RedisExecute<T> {

    public T Execute(Pipeline pipeline);
}

redisDao对应实现类

package com.lgd.ssh.spider.Dao.Spi;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.log4j.Logger;

import com.lgd.ssh.spider.Dao.RedisDao;

import redis.clients.jedis.Pipeline;
import redis.clients.jedis.Response;

public class RedisDaoSpi extends RedisBaseDao implements RedisDao {

    private Logger logger = Logger.getLogger(RedisDaoSpi.class);

    public void add(final Map<String, String> addMap) {

        if (logger.isDebugEnabled()) {
            logger.debug("start RedisDaoSpi.add");
        }
        RedisExecute(new RedisExecute<Void>() {

            public Void Execute(Pipeline pipeline) {
                pipeline.multi();
                for (Map.Entry<String, String> entry : addMap.entrySet()) {
                    pipeline.setnx(entry.getKey(), entry.getValue());
                }
                pipeline.exec();
                pipeline.syncAndReturnAll();
                return null;
            }

        });
        if (logger.isDebugEnabled()) {
            logger.debug("end RedisDaoSpi.add");
        }
    }

    public void delete(final List<String> deleteList) {

        if (logger.isDebugEnabled()) {
            logger.debug("start RedisDaoSpi.delete");
        }
        RedisExecute(new RedisExecute<Void>() {

            public Void Execute(Pipeline pipeline) {
                pipeline.multi();
                for (String key : deleteList) {
                    pipeline.del(key);
                }

                pipeline.exec();
                pipeline.syncAndReturnAll();
                return null;
            }

        });
        if (logger.isDebugEnabled()) {
            logger.debug("end RedisDaoSpi.delete");
        }
    }

    public void update(final Map<String, String> updateMap) {

        if (logger.isDebugEnabled()) {
            logger.debug("start RedisDaoSpi.update");
        }
        RedisExecute(new RedisExecute<Void>() {

            public Void Execute(Pipeline pipeline) {
                pipeline.multi();
                for (Map.Entry<String, String> entry : updateMap.entrySet()) {
                    pipeline.set(entry.getKey(), entry.getValue());
                }

                pipeline.exec();
                pipeline.syncAndReturnAll();
                return null;
            }

        });
        if (logger.isDebugEnabled()) {
            logger.debug("end RedisDaoSpi.update");
        }
    }

    public Map<String, String> query(final List<String> queryList) {

        if (logger.isDebugEnabled()) {
            logger.debug("start RedisDaoSpi.query");
        }
        Map<String, String> getMap = RedisExecute(new RedisExecute<Map<String, String>>() {

            public Map<String, String> Execute(Pipeline pipeline) {

                Map<String, Response<String>> getMap = new HashMap<String, Response<String>>();
                pipeline.multi();

                for (String key : queryList) {
                    getMap.put(key, pipeline.get(key));
                }
                pipeline.exec();

                pipeline.syncAndReturnAll();

                Map<String, String> resultMap = new HashMap<String, String>();
                for (Map.Entry<String, Response<String>> entry : getMap.entrySet()) {
                    resultMap.put(entry.getKey(), entry.getValue().get());
                }
                return resultMap;
            }

        });

        if (logger.isDebugEnabled()) {
            logger.debug("end RedisDaoSpi.query");
        }
        return getMap;
    }

}

4.bean配置
