Redis-Java中使用

Redis在Java中使用

Maven依赖包：

<dependency>    <groupId>redis.clients</groupId>    <artifactId>jedis</artifactId>    <version>2.8.0</version></dependency>

如果redis与我们的开发环境不在同一台机器上的话是需要设置密码的，原因：

If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

上面提到的4种方法，只有设置密码是最根本的！

于是在我们的安装目录下找到 redis.conf 设置密码，这里我设置为redis，密码就是名字，好记！~

requirepass redis

或者

127.0.0.1:6379> config get requirepass1) "requirepass"2) ""127.0.0.1:6379> config set requirepass "redis"  #修改密码OK127.0.0.1:6379> config get requirepass(error) NOAUTH Authentication required.127.0.0.1:6379> auth redis     #需要重新登录OK127.0.0.1:6379> config get requirepass1) "requirepass"2) "redis"

测试

测试代码：

public class RedisTest {    public static void main(String args[]){        //链接远程的服务        Jedis jedis = new Jedis("192.168.1.140",6379);        jedis.auth("redis");        System.out.println("Connection to server sucessfully");        //查看服务是否运行        System.out.println("Server is running: "+jedis.ping());           //String        jedis.set("age","180");        System.out.println("get age:"+jedis.get("age"));    }}

输出：

Connection to server sucessfullyServer is running: PONGget age:180
