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

redis.properties文件

# Redis settings
redis.host=localhost
redis.port=6379
redis.pass=P@ssw0rd

redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true
