• dubbo系列(二) 完整SpringMVC项目整合druid redis zookeeper mybatis dubbo spring-data-redis实现分布式session


    1 项目图(下图为gif动图):技术及框架 SpringMVC druid redis zookeeper mybatis mysql dubbo

    2 自定义session管理(下图为gif动图): 在请求参数里带有sessionId,业务方法使用RequestData获取和保存数据,aop实现保存RequestData的session数据到redis中,这种session管理方式适合给接口使用

    3 数据库连接池druid

    4 zookeeper配置.gif

    ps 4.1 java操作zookeeper的入门可以参考这篇博客(https://www.cnblogs.com/shay-zhangjin/tag/zookeeper/)

    5 事务测试.gif

    6 REST风格 PUT方法测试

    7 dubbo-admin管理后台

    这里的配置<dubbo:application name="category"/> 服务提供者和服务消费者应用名可以不一样的,主要用于依赖分析,与服务调用没有关系的。

    8 使用sping-data-redis实现分布式session最终效果

    8.1 代码

    8.1.1 web.xml增加一个filter

    <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring*.xml</param-value>
     </context-param>
        <filter>
            <filter-name>springSessionRepositoryFilter</filter-name>
            <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        </filter>
        <filter-mapping>
            <filter-name>springSessionRepositoryFilter</filter-name>
            <url-pattern>/*</url-pattern>
            <dispatcher>REQUEST</dispatcher>
            <dispatcher>ERROR</dispatcher>
        </filter-mapping>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

    8.1.2 Controller

        private  static  final  String KEY ="existAttr";
        @RequestMapping("/springSession")
        @ResponseBody
        public  Map<String,Object>  springSession(HttpSession httpSession,String keyPart, HttpServletRequest request){
            Map<String,Object> resultMap=new HashMap<>();
            resultMap.put(KEY, httpSession.getAttribute(KEY));
            httpSession.setAttribute(KEY,CommonUtil.generatorUUID(null)+keyPart);
            resultMap.put("newAttr",  httpSession.getAttribute(KEY));
    
            String server=request.getLocalAddr()+":"+request.getLocalPort();
            resultMap.put("server",server);
            return  resultMap;
        }

    8.1.3 spring其他内容配置

        可以参考这篇博客(https://www.cnblogs.com/youzhibing/p/7348337.html)

    8.1.4 nginx增加配置

    location /dubbostudy-web {
    	proxy_pass http://dubbostudy-web;
    	proxy_set_header Host $host;
    	proxy_set_header X-Real-IP $remote_addr;
    	proxy_set_header REMOTE-HOST $remote_addr;
    	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
    
    
    upstream dubbostudy-web{
         server 192.168.10.132:8083 weight=1;
         server 192.168.10.132:8084 weight=1;
    }
