使用java连接Redis,Maven管理操作

pom配置

 4.0.0

创建db.properties文件

redis.host=bigdata-hpsk01.huadian.com
redis.port=6379
redis.maxIdle=10
redis.minIdle=10
redis.maxTotal=50

书写工具类

package com.huadian.redisUntil;

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

public final class JedisPoolUntil {
 private static String ADDR = "192.168.59.160";
 //Redis的端口号
 private static int PORT = 6379;

 

 private static int MAXTOTAL=20;
 private static int MINIDLE=10;
 private static int MAXIDLE=15;
 private static JedisPool jedisPool = null;
 
 static {
 try {
  JedisPoolConfig config = new JedisPoolConfig();
  config.setMaxTotal(MAXTOTAL);
  config.setMaxIdle(MINIDLE);
  config.setMinIdle(MAXIDLE);

  jedisPool = new JedisPool(config, ADDR, PORT);
  } catch (Exception e) {
  e.printStackTrace();
  }
 }

 
 public synchronized static Jedis getJedis() {
  try {
  if (jedisPool != null) {
   Jedis resource = jedisPool.getResource();
   return resource;
  } else {
   return null;
  }
  } catch (Exception e) {
  e.printStackTrace();
  return null;
  }
 }

 
 public static void returnResource(final Jedis jedis) {
 if (jedis != null) {
  jedisPool.returnResource(jedis);
  }
 }
}

书写测试类

package com.huadian.jedis;

import com.huadian.redisUntil.JedisPoolUntil;
import org.junit.Test;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

public class JedisDemo {
 private Jedis jedis = null;

 
 @Test
 public void jedisSingleConn(){
 String host = "192.168.59.160";
 int port = 6379;
 Jedis jedis = new Jedis(host, port);
 jedis.set("name","张三");
 jedis.set("age","18");
 String s = jedis.get("name");
 String s1 = jedis.get("age");
 System.out.println(s);
 System.out.println(s1);
 }
 
 @Test
 public void jedisPoolConn(){
 JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
 jedisPoolConfig.setMaxTotal(20);
 jedisPoolConfig.setMinIdle(10);
 jedisPoolConfig.setMaxIdle(15);
 JedisPool jedisPool = new JedisPool(jedisPoolConfig, "192.168.59.160", 6379);
 Jedis jedis = jedisPool.getResource();
 //取数据
 String s = jedis.get("name");
 String s1 = jedis.get("age");
 System.out.println(s);
 System.out.println(s1);
 }
 
 @Test
 public void jedisPoolConn1(){
 Jedis jedis1 = JedisPoolUntil.getJedis();
 //取数据
 String s = jedis1.get("name");
 String s1 = jedis1.get("age");
 System.out.println(s);
 System.out.println(s1);
 }
}

补充知识：JAVA使用Redis所需的MAVEN的POM文件

redis不仅可以通过命令行进行操作，同时redis也可以通过javaAPI进行操作,这是操作redis所需的依赖

  
   redis.clients
   jedis
   2.9.0
  
  
   junit
   junit
   4.12
   test
  
  
   org.testng
   testng
   6.14.3
   test
  
 
 
  
   
    org.apache.maven.plugins
    maven-compiler-plugin
    3.0
    
     1.8
     1.8
     UTF-8
