Jedis连接外部Redis
1.在服务器开放端口redis默认6379，如果有宝塔面板则还需要在宝塔放行6379端口
2.修改redis.conf
注释掉 绑定IP 127.0.0.1
# bind 127.0.0.1
设置redis密码
requirepass
3.项目导入依赖
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
4.applicaiton.yml添加配置（密码要加双引号）
spring:
redis:
host: 120.57.56.220
port: 6379
password: "123456"
jedis:
pool:
max-active: 8
max-idle: 8
min-idle: 2
timeout: 2000
5.添加配置类
@Configuration
public class JedisConfig {
private Logger logger = LoggerFactory.getLogger(JedisConfig.class);
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.password}")
private String password;
@Value("${spring.redis.timeout}")
private int timeout;
@Value("${spring.redis.jedis.pool.max-active}")
private int maxActive;
@Value("${spring.redis.jedis.pool.max-idle}")
private int maxIdle;
@Value("${spring.redis.jedis.pool.min-idle}")
private int minIdle;
@Bean
public JedisPool jedisPool(){
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxIdle(maxIdle);
jedisPoolConfig.setMinIdle(minIdle);
jedisPoolConfig.setMaxTotal(maxActive);
JedisPool jedisPool = new JedisPool(jedisPoolConfig,host,port,timeout,password);
logger.info("JedisPool连接成功: "+host+"/"+port );
return jedisPool;
}
}
6.通过JedisPool获取Jedis调用方法
@Autowired
private JedisPool jedisPool;
public String getValue(String key) {
String value = null;
Jedis jedis = jedisPool.getResource();
if (jedis.exists(key)){
log.info("通过Redis取值");
value = jedis.get(key);
}else {
log.info("通过Mysql取值");
value = "value";
jedis.set(key,value);
}
jedis.close();
return value;
}
