摘要：并沒(méi)有因?yàn)椴灰恢露煌褂眠B接，確實(shí)存儲(chǔ)了一個(gè)，如下工程目錄實(shí)際操縱過(guò)程中遇到一個(gè)問(wèn)題啟動(dòng)工程的時(shí)候報(bào)錯(cuò)解決方法對(duì)于依賴，增加了一個(gè)，且版本為。啟動(dòng)，未報(bào)錯(cuò)，問(wèn)題解決。后續(xù)有時(shí)間再研究。

1.環(huán)境信息
nginx-1.11.10
redis-latest包（redis windows版本）
springboot1.5.1.RELEASE

2.新建一個(gè)SpringBoot項(xiàng)目，參考如下鏈接：https://segmentfault.com/a/11...

3.nginx和redis解壓縮即可，并正常啟動(dòng)

4.springboot集成Redis以及springboot，需要在POM文件中增加依賴

    
    
    4.0.0

    com.example
    demo3
    0.0.1-SNAPSHOT
    jar

    demo
    Demo project for Spring Boot

    
        org.springframework.boot
        spring-boot-starter-parent
        1.5.1.RELEASE
         
    

    
        UTF-8
        UTF-8
        1.8
    

    
        
            org.springframework.boot
            spring-boot-starter
        
        
             org.springframework
             spring-context-support
             4.3.5.RELEASE
        
          
            org.springframework.boot  
            spring-boot-starter-web  
            
          
            org.springframework.session  
            spring-session-data-redis  
          
          
          org.springframework.boot  
          spring-boot-starter-redis
          1.3.8.RELEASE  
          
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
      
        org.springframework.data
        spring-data-redis
     
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    


    

5.新建Controller類DemoController.java

@Controller
public class DemoController {
    @Autowired  
    DemoService demoService;  
     
    @RequestMapping("testcache")
    @ResponseBody
    public String testCache(@RequestParam String key){
        String s = demoService.testCache(key);
        return s;
    }
    
    @RequestMapping("/getseansession")
    @ResponseBody
    public Map getSession(HttpServletRequest request){
        Map attributeMap = new HashMap();
        request.getSession().setAttribute("message", request.getRequestURI());
        attributeMap.put("message", request.getRequestURI());
        System.out.println("sessionID:" + request.getSession().getId());
        return attributeMap;
    }
}

6.新建Service類DemoService.java

@Service
public class DemoService {
    @Cacheable(value = "keycache")
    public String testCache(String key){
        System.out.println("testCache:" + key);
        return key;
    }
}

7.新建RedisConfig類增加@EnableRedisHttpSession注解

@Configuration  
@EnableCaching
@EnableRedisHttpSession
public class RedisConfig{
}

8.application.properties文件配置，其中為了測(cè)試ngnix負(fù)載均衡功能，本工程配置為8080端口，另一個(gè)springboot工程可以配置為別的端口，比如8088，以便啟動(dòng)兩個(gè)Server

#redis spring.redis.password=xxx
#spring.redis.database= # database name  
spring.redis.hostname=127.0.0.1 # server host
spring.redis.port=6379  
spring.redis.pool.maxActive=8  
spring.redis.pool.maxWait=-1  
spring.redis.pool.maxIdle=8  
spring.redis.pool.minIdle=0  
spring.redis.timeout=0

#tomcat port configuration
server.port=8080

可以看到啟動(dòng)了兩個(gè)Server，DemoApplication和DemoApplication(1)

9.ngnix.conf配置文件中配置負(fù)載均衡策略

upstream test {
        server localhost:8080;
        server localhost:8088;
    }
    
    server {
        listen       80;
        server_name  localhost;
        client_max_body_size 1024M;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        #location / {
        #    root   html;
        #    index  index.html index.htm;
        #}

        location / {
            proxy_pass http://test/getseansession;
            proxy_set_header Host $host:$server_port;
        }

10.訪問(wèn)http://localhost，會(huì)發(fā)現(xiàn)http請(qǐng)求交替訪問(wèn)后端兩個(gè)server。且sessionID是一樣的“sessionID:ad0cbb3b-d24d-4d61-87ac-b9ddcfeccaa4”。并沒(méi)有因?yàn)閟erver不一致而sessionID不同

使用RedisClient連接Redis Server，確實(shí)存儲(chǔ)了一個(gè)sessionID，如下：

11.maven工程目錄

12.實(shí)際操縱過(guò)程中遇到一個(gè)問(wèn)題：?jiǎn)?dòng)springboot工程的時(shí)候報(bào)錯(cuò)“java.lang.IllegalStateException: Cannot load configuration class: org.springframework.boot.autoconfigure.cache.RedisCacheConfiguration”

解決方法：對(duì)于spring-context-support依賴，增加了一個(gè)version，且版本為4.3.5.RELEASE。啟動(dòng)，未報(bào)錯(cuò)，問(wèn)題解決。沒(méi)配version的時(shí)候，默認(rèn)是4.3.6.RELEASE，奇怪。后續(xù)有時(shí)間再研究。

        
             org.springframework
             spring-context-support
             4.3.5.RELEASE
