How single authentication can work for multiple server nodes in Spring Security - spring-boot

Question

I am using weblogic for deploying my spring boot application, and my same application is deployed on multiple nodes.
For example the two node in which the application is deployed is 9001 and 9002.
With basic security even if I am authenticated on the Node 9001 and trying to access the same URL on second node i.e on 9002, I am again getting redirected again to spring login page for authentication.
I want that once I authenticate using username and password on any node. I need not to authenticate again, Even if I am requesting to any other node.
Any kind of clue or help will be appreciated.
Thanks in advance.
The Security configuration file is
package com.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("test")
.password("{noop}test")
.authorities("USER");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/userdetail").authenticated()
.anyRequest().permitAll()
.and()
.formLogin();
}
}

In my case it worked for both node when I enabled RedisHttpSession.
Below is the code which worked for me.
#Configuration
#EnableRedisHttpSession
public class RedisConfig {
#Bean
public JedisConnectionFactory connectionFactory() {
return new JedisConnectionFactory();
}
}
also in pom.xml I needed to make two dependencies(For Spring boot).
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>
You can also take reference about EnableRedisHttpSession from spring docs, and about spring session from
https://docs.spring.io/spring-session/docs/current/api/org/springframework/session/data/redis/config/annotation/web/http/EnableRedisHttpSession.html
