Jedis的使用。

安装redis：上网查，本文基于已经安装了redis。在java中对redis操作。

导入依赖：

 <dependency>
 <groupId>redis.clients</groupId>
 <artifactId>jedis</artifactId>
<version>3.7.0</version>
</dependency>

创建jedis工具类和连接池（连接池可以不用）

工具类：

package dt;//包名

import redis.clients.jedis.Jedis;

public class JedisUnit {
    private String host="127.0.0.1"; //链接地址
    private Integer port=6379;//链接端口号,默认6379
    private Integer dataBase=0;//数据库号(0-16)，默认为0
    private String pasd;//密码，没有修改配置文件默认没有

    public String getPasd() {
        return pasd;
    }

    public void setPasd(String pasd) {
        this.pasd = pasd;
    }

    private Jedis jedis;

    public JedisUnit() {}

    public JedisUnit(String host, Integer port, String pasd,Integer dataBase) {
        this.host = host;
        this.port = port;
        this.pasd = pasd;
        this.dataBase = dataBase;
    }

    public JedisUnit(String host, Integer port, Integer dataBase) {
        this.host = host;
        this.port = port;
        this.dataBase = dataBase;
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public Integer getPort() {
        return port;
    }

    public void setPort(Integer port) {
        this.port = port;
    }

    public Integer getDataBase() {
        return dataBase;
    }

    public void setDataBase(Integer dataBase) {
        this.dataBase = dataBase;
    }

    public Jedis connect(){
        jedis = new Jedis(host,port);
        jedis.auth(pasd);
        jedis.select(dataBase);
        return jedis;
    }
    public void close(){
        if (jedis!=null)
            jedis.close();
    }

}

连接池工具类：

package dt;//包名

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

public class JedisPoolFact {
    private Integer maxTotle=8;//最多连接数，默认8
    private Integer maxIdl=8;//最多连接数，默认8
    private Integer waitting=1000;//等待时长默认1s

    private  JedisUnit jedisUnit;


    public JedisPoolFact() {}

    public JedisPoolFact(JedisUnit jedisUnit) {
        this.jedisUnit = jedisUnit;
    }

    public JedisPoolFact(Integer maxTotle, Integer maxIdl, Integer waitting, JedisUnit jedisUnit) {
        this.maxTotle = maxTotle;
        this.maxIdl = maxIdl;
        this.waitting = waitting;
        this.jedisUnit = jedisUnit;
    }

    public Jedis jedisPoolConnect(){
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        poolConfig.setMaxIdle(maxIdl);
        poolConfig.setMaxTotal(maxTotle);
        poolConfig.setMinIdle(0);
        poolConfig.setMaxWaitMillis(waitting);
        JedisPool jedisPool = new JedisPool(poolConfig,jedisUnit.getHost(), jedisUnit.getPort(),1000,jedisUnit.getPasd());
        return  jedisPool.getResource();
    }
}

测试类:

import dt.JedisPoolFact;
import dt.JedisUnit;
import org.junit.Test;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;

public class JedisTest {
    JedisUnit jedisUnit = new JedisUnit();
    JedisPoolFact jedisPoolFact = new  JedisPoolFact(jedisUnit);

    @Test
    public void  test1(){
        Jedis jedis = jedisPoolFact.jedisPoolConnect();//使用连接池
        //Jedis jedis = jedisUnit.connect();//使用连接池
        jedis.set("name","阿里妈妈");
        System.out.println(jedis.get("name"));
        jedisUnit.close();
    }
}
