这篇文章主要介绍了Java链接redis，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

要在Java程序中使用使用操作Redis，需要确保有Redis的Java驱动程序和Java设置在机器上。现在，让我们来看看如何设置Redis的Java驱动程序。

需要下载jedis.jar。请一定要下载它的最新版本。
需要包括jedis.jar到你的类路径中。

连接到Redis服务器

									import redis.clients.jedis.Jedis;

									public class RedisJava {

									 public static void main(String[] args) {

									  //Connecting to Redis server on localhost

									  Jedis jedis = new Jedis("localhost");

									  System.out.println("Connection to server sucessfully");

									  //check whether server is running or not

									  System.out.println("Server is running: "+jedis.ping());

									 }

									}

现在，让我们来编译和运行上面的程序来测试连接Redis服务器。你可以根据实际情况改变路径。这里假设jedis.jar的当前版本在当前路径中可用

									$javac RedisJava.java

									$java RedisJava

									Connection to server sucessfully

									Server is running: PONG

Redis和Java字符串实例

									import redis.clients.jedis.Jedis;

									public class RedisStringJava {

									 public static void main(String[] args) {

									  //Connecting to Redis server on localhost

									  Jedis jedis = new Jedis("localhost");

									  System.out.println("Connection to server sucessfully");

									  //set the data in redis string

									  jedis.set("tutorial-name", "Redis tutorial");

									  // Get the stored data and print it

									  System.out.println("Stored string in redis:: "+ jedis.get("tutorial-name"));

									 }

									}

现在，让我们编译并运行上述程序。

									$javac RedisStringJava.java

									$java RedisStringJava

									Connection to server sucessfully

									Stored string in redis:: Redis tutorial

Redis和Java列表示例

									import redis.clients.jedis.Jedis;

									public class RedisListJava {

									 public static void main(String[] args) {

									  //Connecting to Redis server on localhost

									  Jedis jedis = new Jedis("localhost");

									  System.out.println("Connection to server sucessfully");

									  //store data in redis list

									  jedis.lpush("tutorial-list", "Redis");

									  jedis.lpush("tutorial-list", "Mongodb");

									  jedis.lpush("tutorial-list", "Mysql");

									  // Get the stored data and print it

									  List<String> list = jedis.lrange("tutorial-list", 0 ,5);

									  for(int i=0; i<list.size(); i++) {

									  System.out.println("Stored string in redis:: "+list.get(i));

									  }

									 }

									}

现在，让我们编译并运行上述程序。

									$javac RedisListJava.java

									$java RedisListJava

									Connection to server sucessfully

									Stored string in redis:: Redis

									Stored string in redis:: Mongodb

									Stored string in redis:: Mysql

Redis和Java的键实例

									import redis.clients.jedis.Jedis;

									public class RedisKeyJava {

									 public static void main(String[] args) {

									  //Connecting to Redis server on localhost

									  Jedis jedis = new Jedis("localhost");

									  System.out.println("Connection to server sucessfully");

									  //store data in redis list

									  // Get the stored data and print it

									  List<String> list = jedis.keys("*");

									  for(int i=0; i<list.size(); i++) {

									  System.out.println("List of stored keys:: "+list.get(i));

									  }

									 }

									}

现在，让我们编译并运行上述程序。

									$javac RedisKeyJava.java

									$java RedisKeyJava

									Connection to server sucessfully

									List of stored keys:: tutorial-name

									List of stored keys:: tutorial-list
