1.pom文件中添加依赖
org.springframework.boot spring-boot-starter-redis org.springframework.session spring-session-data-redis
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=localhost
4.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; 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; import java.util.logging.Level; import java.util.logging.Logger; @SpringBootApplication @RestController public class SleuthServerMiyaApplication { public static void main(String[] args) { SpringApplication.run(SleuthServerMiyaApplication.class, args); } private static final Logger LOG = Logger.getLogger(SleuthServerMiyaApplication.class.getName()); @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 @LoadBalanced public RestTemplate getRestTemplate(){ return new RestTemplate(); } @Bean public Sampler defaultSampler() { return Sampler.ALWAYS_SAMPLE; } }
