SpringBoot项目集成SpringSession,使用redis实现会话共享.做到可配置.

 

 前提:公司开发产品,对接不同省份,一起开发,有些地方需要实现redis会话共享,有些地方是单机部署.可通过配置是否开启redis实现session共享.

 SpringBoot集成SpringSession实现会话共享:

   主要是通过application.properties里面的spring.session.store-type=none参数配置.none单机版.redis会话共享

• pom添加依赖

		
			org.springframework.session
			spring-session
		

• application.properties添加session和redis配置

#session 
#配合为redis表示开启redis会话共享,none单机
spring.session.store-type=none
spring.session.redis.namespace=evidence

#redis配置
spring.data.redis.repositories.enabled=true
spring.redis.database=0
spring.redis.host=
spring.redis.port=6379
spring.redis.pool.max-active=1024
spring.redis.pool.min-idle=10

• 添加SpringSession的配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
import org.springframework.session.web.http.CookieHttpSessionStrategy;
import org.springframework.session.web.http.CookieSerializer;

@Configuration
public class SpringSessionConfig {

	@Bean
	public CookieHttpSessionStrategy cookieHttpSessionStrategy() {
		CookieHttpSessionStrategy strategy = new CookieHttpSessionStrategy();
		strategy.setCookieSerializer(buildCustomerCookieSerializer());
		return strategy;
	}

	private CookieSerializer buildCustomerCookieSerializer() {
		// TODO Auto-generated method stub
		return new CustomerCookieSerializer();
	}

}

 

• 使用Jackson2JsonRedisSerialize 替换默认序列化 

import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Primary;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.session.SessionRepository;
import org.springframework.session.config.annotation.web.http.SpringHttpSessionConfiguration;
import org.springframework.session.data.redis.RedisOperationsSessionRepository;
import org.springframework.session.web.http.CookieSerializer;
import org.springframework.session.web.http.DefaultCookieSerializer;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.MapperFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;


public class ApplicationStartup  implements ApplicationListener {

	@Override
	public void onApplicationEvent(ApplicationReadyEvent event) {
		// TODO Auto-generated method stub
		RedisSerializer
