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;
    }

8.1.4 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;
