redis单机和集群测试使用工具类

这里的环境需要提前搭建好,这些工具类用的还不错

添加Maven依赖:

		
		
			redis.clients
			jedis
			2.7.2
		
	    
			junit
			junit
			4.12
			test
		

添加Maven依赖:

使用连接池测试单机版redis:

	@Test
	public void testJedisPool() throws Exception {
		// 创建一个连接池对象,两个参数host、port
		JedisPool jedisPool = new JedisPool("192.168.25.155", 6379);
		// 从连接池获得一个连接,就是一个jedis对象。
		Jedis jedis = jedisPool.getResource();
		// 使用jedis操作redis
		String string = jedis.get("bwcx9393");
		System.out.println(string);//输出内容:欢迎关注微信公众号:Java面试通关手册
		// 关闭连接,每次使用完毕后关闭连接。连接池回收资源。
		jedis.close();
		// 关闭连接池。
		jedisPool.close();
	}

测试集群版redis:

	@Test
	public void testJedisCluster() throws Exception {
		// 创建一个JedisCluster对象。有一个参数nodes是一个set类型。set中包含若干个HostAndPort对象。
		Set nodes = new HashSet<>();
		nodes.add(new HostAndPort("192.168.25.155", 7001));
		nodes.add(new HostAndPort("192.168.25.155", 7002));
		nodes.add(new HostAndPort("192.168.25.155", 7003));
		nodes.add(new HostAndPort("192.168.25.155", 7004));
		nodes.add(new HostAndPort("192.168.25.155", 7005));
		nodes.add(new HostAndPort("192.168.25.155", 7006));
		JedisCluster jedisCluster = new JedisCluster(nodes);
		// 直接使用JedisCluster对象操作redis。
		jedisCluster.set("test", "123");
		String string = jedisCluster.get("test");
		System.out.println(string);
		// 关闭JedisCluster对象
		jedisCluster.close();
	}


集群和单机在项目中无缝链接

 

接口

import java.util.List;

public interface JedisClient {

	String set(String key, String value);
	String get(String key);
	Boolean exists(String key);
	Long expire(String key, int seconds);
	Long ttl(String key);
	Long incr(String key);
	Long hset(String key, String field, String value);
	String hget(String key, String field);
	Long hdel(String key, String... field);
	Boolean hexists(String key, String field);
	List hvals(String key);
	Long del(String key);
}

集群版使用:

import java.util.List;

import redis.clients.jedis.JedisCluster;

public class JedisClientCluster implements JedisClient {
	
	private JedisCluster jedisCluster;
	

	public JedisCluster getJedisCluster() {
		return jedisCluster;
	}

	public void setJedisCluster(JedisCluster jedisCluster) {
		this.jedisCluster = jedisCluster;
	}

	@Override
	public String set(String key, String value) {
		return jedisCluster.set(key, value);
	}

	@Override
	public String get(String key) {
		return jedisCluster.get(key);
	}

	@Override
	public Boolean exists(String key) {
		return jedisCluster.exists(key);
	}

	@Override
	public Long expire(String key, int seconds) {
		return jedisCluster.expire(key, seconds);
	}

	@Override
	public Long ttl(String key) {
		return jedisCluster.ttl(key);
	}

	@Override
	public Long incr(String key) {
		return jedisCluster.incr(key);
	}

	@Override
	public Long hset(String key, String field, String value) {
		return jedisCluster.hset(key, field, value);
	}

	@Override
	public String hget(String key, String field) {
		return jedisCluster.hget(key, field);
	}

	@Override
	public Long hdel(String key, String... field) {
		return jedisCluster.hdel(key, field);
	}

	@Override
	public Boolean hexists(String key, String field) {
		return jedisCluster.hexists(key, field);
	}

	@Override
	public List hvals(String key) {
		return jedisCluster.hvals(key);
	}

	@Override
	public Long del(String key) {
		return jedisCluster.del(key);
	}

}

单机版使用:


import java.util.List;

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

public class JedisClientPool implements JedisClient {
	
	private JedisPool jedisPool;

	public JedisPool getJedisPool() {
		return jedisPool;
	}

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

	@Override
	public String set(String key, String value) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.set(key, value);
		jedis.close();
		return result;
	}

	@Override
	public String get(String key) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.get(key);
		jedis.close();
		return result;
	}

	@Override
	public Boolean exists(String key) {
		Jedis jedis = jedisPool.getResource();
		Boolean result = jedis.exists(key);
		jedis.close();
		return result;
	}

	@Override
	public Long expire(String key, int seconds) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.expire(key, seconds);
		jedis.close();
		return result;
	}

	@Override
	public Long ttl(String key) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.ttl(key);
		jedis.close();
		return result;
	}

	@Override
	public Long incr(String key) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.incr(key);
		jedis.close();
		return result;
	}

	@Override
	public Long hset(String key, String field, String value) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.hset(key, field, value);
		jedis.close();
		return result;
	}

	@Override
	public String hget(String key, String field) {
		Jedis jedis = jedisPool.getResource();
		String result = jedis.hget(key, field);
		jedis.close();
		return result;
	}

	@Override
	public Long hdel(String key, String... field) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.hdel(key, field);
		jedis.close();
		return result;
	}

	@Override
	public Boolean hexists(String key, String field) {
		Jedis jedis = jedisPool.getResource();
		Boolean result = jedis.hexists(key, field);
		jedis.close();
		return result;
	}

	@Override
	public List hvals(String key) {
		Jedis jedis = jedisPool.getResource();
		List result = jedis.hvals(key);
		jedis.close();
		return result;
	}

	@Override
	public Long del(String key) {
		Jedis jedis = jedisPool.getResource();
		Long result = jedis.del(key);
		jedis.close();
		return result;
	}

}

applicationContext-redis.xml



	
	
	
		
	
	
		
		
	
	

测试代码:

public class JedisClientTest {

	@Test
	public void testJedisClient() throws Exception {
		//初始化spring容器
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-redis.xml");
		//从容器中获得JedisClient对象
		JedisClient jedisClient = applicationContext.getBean(JedisClient.class);
		jedisClient.set("aaa", "111");
		String string = jedisClient.get("aaa");
		System.out.println(string);
		
		
	}
}
