今天就跟大家聊聊有关使用SpringCloud怎么实现Redis在各个微服务Session共享，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
1.pom文件中添加依赖
计算
安全
数据库
网络和加速
企业服务
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>2.使用Redis的session替换Spring的session
package com.xueqing.demo.sleuthserverhi;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
/**
* 添加redis配置类启用redis代码spring默认session
*/
@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
}3.application.properties配置文件中添加redis配置
spring.redis.port= 6379
spring.redis.host=localhost4.启动两个端口以一样的tomcat测试
package com.xueqing.demo.sleuthserverhi;
import java.util.logging.Level;
import java.util.logging.Logger;
import brave.sampler.Sampler;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import javax.servlet.http.HttpServletRequest;
@SpringBootApplication
@RestController
public class SleuthServerHiApplication {
public static void main(String[] args) {
SpringApplication.run(SleuthServerHiApplication.class, args);
}
private static final Logger LOG = Logger.getLogger(SleuthServerHiApplication.class.getName());
@Autowired
private RestTemplate restTemplate;
@Bean
@LoadBalanced
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/hi")
public String callHome(HttpServletRequest request){
LOG.log(Level.INFO, "calling trace service-hi ");
request.getSession().setAttribute("hi","111");
LOG.log(Level.WARNING, "加入成功");
return restTemplate.getForObject("http://localhost:8989/miya", String.class);
}
@RequestMapping("/info")
public String info(HttpServletRequest request){
LOG.log(Level.INFO, request.getSession().getAttribute("miya")+"");
LOG.log(Level.WARNING, "获取成功");
return "i'm service-hi";
}
@Bean
public Sampler defaultSampler() {
return Sampler.ALWAYS_SAMPLE;
}
}
package com.xueqing.demo.sleuthservermiya;
import brave.sampler.Sampler;

@RequestMapping("/hi")
public String home(HttpServletRequest request){
LOG.log(Level.INFO, "hi is being called");
request.getSession().setAttribute("miya","111");
LOG.log(Level.WARNING, "加入成功");
return "hi i'm miya!";
}
@RequestMapping("/miya")
public String info(HttpServletRequest request){
LOG.log(Level.INFO, "info is being called");
LOG.log(Level.INFO, request.getSession().getAttribute("hi")+"");
LOG.log(Level.WARNING, "获取成功");
return restTemplate.getForObject("http://localhost:8988/info",String.class);
}
@Autowired
private RestTemplate restTemplate;

}
@Bean
public Sampler defaultSampler() {
return Sampler.ALWAYS_SAMPLE;
}
