在Java程序中使用Redis之前，需要确保在机器上安装了Redis的Java驱动程序和Java环境。可以先在将Java电脑上并配置好环境。

安装

现在，让我们看看如何设置Redis Java驱动程序。

下载jedis.jar - http://repo1.maven.org/maven2/redis/clients/jedis/2.1.0/jedis-2.1.0-sources.jar ，确保下载的jedis.jar是最新版本。
将jedis.jar包含到类路径中。

Java连接到Redis服务器

请参考以下一个简单的示例代码 -

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，编译并运行上面的程序来测试与Redis服务器的连接。可以根据需要更改路径。假设jedis.jar的当前版本在当前路径中可以使用。
执行上面代码，将生成以下结果 -

$javac RedisJava.java 
$java RedisJava 
Connection to server sucessfully 
Server is running: PONG

Redis Java字符串示例

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("tutorialname")); } }

执行上面代码，将生成以下结果 -

$javac RedisStringJava.java 
$java RedisStringJava 
Connection to server sucessfully 
Stored string in redis:: Redis tutorial

Redis 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)); } } }

执行上面代码，将生成以下结果

$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 Java键示例

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)); } } }

执行上面代码，将生成以下结果 -

$javac RedisKeyJava.java 
$java RedisKeyJava 
Connection to server sucessfully 
List of stored keys:: tutorial-name 
List of stored keys:: tutorial-list
