java使用redis，配置jedis

java使用jedis连接redis需要的所有jar

或者用pom.xml配置jar

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>

jedis配置类ConnectionManager 用于配置获取jedis

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

public class ConnectionManager {

    private static final String redis_host = "127.0.0.1";
    private static final int redis_port = 6379;
    private static final int redis_timeout = 2000;
    private static final String redis_password = "pwd";

    private static JedisPool pool;

    static {
        JedisPoolConfig config = new JedisPoolConfig();
        // 控制一个pool可分配多少个jedis实例，通过pool.getResource()来获取；
        // pool = new JedisPool(config, redis_host, 6379);
        pool = new JedisPool(config, redis_host, redis_port, redis_timeout, redis_password);
    }

    public static void main(String[] args) throws Exception {
        pool = new JedisPool(new JedisPoolConfig(), redis_host, redis_port, 3000, redis_password);
        Jedis jedis = pool.getResource();
        jedis.set("a", "abc");
        System.out.println("redis中的值：" + jedis.get("a"));

        closeConnection(jedis);
    }
    /**
     * 获取连接
     * @return
     * @throws Exception
     */
    public static synchronized Jedis getConnection() throws Exception {
        try {
            return pool.getResource();
        } catch (Exception e) {
            throw e;
        }
    }
    /**
     * 关闭连接
     * @param connection
     * @throws Exception
     */
    public static synchronized void closeConnection(Jedis connection) throws Exception {
        try {
            if (connection != null && connection.isConnected()) {
                connection.close();
            }
        } catch (Exception e) {
            throw e;
        }
    }

}
