Spring boot unable to connect redis client Jedis to pool: Connection refused - spring-boot

Question

I'm new to Spring boot development and all I want is to enable a Session for an Admin user. I'm writing a REST stateless (API) and a stateful service and I'm following a tutorial which is using redis in-memory-database for storing user sessions. I'm already using MySQL/JDBC for storing other data. Using redis and jdbc doesn't conflict?
In order to enable user session, I made the following:
These are the dependencies that I have added lately:
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-security -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>

</dependency>

Creating a Jedis Connection Factory:
#Configuration
#EnableRedisHttpSession
public class SessionConfig extends AbstractHttpSessionApplicationInitializer {
#Bean
public JedisConnectionFactory jedisConnectionFactory() {
return new JedisConnectionFactory();
}
}
And the secured http configuration:
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("admin").password("password").roles("ADMIN");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.httpBasic().and()
.authorizeRequests()
.antMatchers("/").hasRole("ADMIN")
.anyRequest().authenticated();
}
}
I have also added the redis connection hostname and port in the application.properties:
# ===============================
# = REDIS
# ===============================
spring.redis.host=localhost
spring.redis.port=6379
However, when I run the application, the following error is thrown:
Caused by: java.net.ConnectException: Connection refused: connect

I have tried to change localhost to 192.168.1.2 (my PC's local IP), tried to change the port but the connection is still refused.
This is the stacktrace first line:
[restartedMain] ERROR o.s.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource [org/springframework/session/data/redis/config/annotation/web/http/RedisHttpSessionConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
I don't know what else I could do. I'm having an antivirus (Windows). Should I disable it? Should I disable the firewall? Should I scan the ports to see what ports are opened?
Edit:
I have already tried using redis standalone configuration to pass the hostname and the port, but still can't connect:
public class SessionConfig extends AbstractHttpSessionApplicationInitializer {
#Bean
public JedisConnectionFactory jedisConnectionFactory() {
RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration("127.0.0.1", 6379);
return new JedisConnectionFactory(redisStandaloneConfiguration);
}
}

Answer 1

Configure the Jedis' connection pool:
spring:
redis:
client-type: jedis
jedis:
pool:
enabled: true
max-active: 4
max-idle: 4
max-wait: -10ms
min-idle: 0

Answer 2

If it is localhost. Try with 127.0.0.1:****
Sometimes using ip (192.168.x.x) can give errors ...
# ===============================
# = REDIS
# ===============================
spring.redis.host=127.0.0.1
spring.redis.port=6379
