<content type="html"><![CDATA[<h3 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h3><p>Dubbo作为一款高性能的RPC框架，已经在大多数一线IT企业中得到了广泛的使用，今天我们也来试一试。为了尽可能的少写代码，让程序简单明了，我们基于SpringBoot来搭建。<br>虽然Dubbo推荐使用zk作为注册中心，今天我们换换Redis试试。</p><h3 id="需求分解"><a href="#需求分解" class="headerlink" title="需求分解"></a>需求分解</h3><p>本项目只是为了讲解Dubbo与Redis的使用，所以将业务尽可能地简化，我们的消费方调用服务提供方获取一个简单的用户信息。<br>将业务进行分解：</p><ul><li>接口定义(user-common)</li><li>服务提供方(user-provider)</li><li>服务消费方(user-consumer)</li></ul><h3 id="接口项目"><a href="#接口项目" class="headerlink" title="接口项目"></a>接口项目</h3><p>原则上该项目其实只是接口定义部分就可以了，其实什么依赖都可以不需要，只是为了少写代码，这里引入了lombok，然后将该项目打包发布到maven仓库即可。<br>pom.xml</p><pre class=" language-xml"><code

title="前言"></a>前言</h3><p>使用Redis来实现Session共享，其实网上已经有很多例子了，这是确保在集群部署中最典型的redis使用场景。在SpringBoot项目中，其实可以一行运行代码都不用写，只需要简单添加添加依赖和一行注解就可以实现（当然配置信息还是需要的）。<br>然后简单地把该项目部署到不同的tomcat下，比如不同的端口(A、B)，但项目访问路径是相同的。此时在A中使用set方法，然后在B中使用get方法，就可以发现B中可以获取A中设置的内容。</p><p>但如果就把这样的一个项目在多个tomcat中的部署说实现了单点登录，那就不对了。</p><p>所谓单点登录是指在不同的项目中，只需要任何一个项目登录了，其他项目不需要登录。</p><p>同样是上面的例子，我们把set和get两个方法分别放到两个项目(set、get)中，并且以集群方式把两个项目都部署到服务器A和B中，然后分别访问A服务器的set和B服务器的get，你就会发现完全得不到你想要的结果。</p><h3

session和cookie在默认情况下是与项目路径相关的，在同一个项目的情况下两个方法所需要的cookie依赖的项目路径是相同的，所以获取session的值就没有问题，但在后一种情况下，cookie的路径是分别属于不同的项目的，所以第二个项目就无法获得第一个项目中设置的session内容了。</p><h3 id="解决方法"><a href="#解决方法" class="headerlink" title="解决方法"></a>解决方法</h3><p>解决方法在springboot项目中其实也非常简单。既然cookie路径发生了变化，那我们让它配置为相同的路径就解决了。<br>在每个子项目中都添加一个配置类或者直接设置cookie的路径，如果有域名还可以设置域名的限制，比如 set.xxx.com 与 get.xxx.com 这种情况与我们就需要设置cookie的域名为 xxx.com，以确保无法在哪个项目下都能够获取 xxx.com 这个域名下的cookie值。这样就确保能够正常获得共享的session值了。</p><pre class=" language-java"><code class="language-java"><span class="token annotation punctuation">@Configuration</span><span

<title>利用nginx与frp/ngrok实现内网穿透，将网站架在自己家里或者公司内部</title>

<title>nginx泛域名http(80)强制跳转https(443)</title>

<content type="html"><![CDATA[<h2 id="nginx泛域名http-80-强制跳转https-443"><a href="#nginx泛域名http-80-强制跳转https-443" class="headerlink" title="nginx泛域名http(80)强制跳转https(443)"></a>nginx泛域名http(80)强制跳转https(443)</h2><p>随着chrome浏览器在地址栏开始标注网站『不安全』的提示开始，各大小网站都开始从http转为https了，并且都更注重网站的安全了。然页我们之前的很多站点都是基于http开发的，如果全部改造成https，必然是很大的工作量，幸好有第三方的工具可以为我们解决这个问题，可以让原有的系统不改动的情况下，或者少改动的情况下就能够满足这个需求。nginx就是其中使用最为广泛的一个，并且它的响应最快，目前国内绝大多数平台或者系统在前端都使用的是nginx或者nginx的变种。</p><p>为每个域名（子域名）申请证书，然后配置nginx，这样就可以解决https证书问题。但为每个域名或者子域名都申请一个证书，暂起不说费用问题，申请也是比较麻烦的事，所以申请一个支持泛域名的能用证书是最方便的，所有子域名都可以使用该证书，肯定是最快捷的。</p><h3 id="泛域名证书申请"><a href="#泛域名证书申请" class="headerlink" title="泛域名证书申请"></a>泛域名证书申请</h3><p>推荐使用acme.sh来申请，下载地址和使用说明</p><pre><code>https://github.com/Neilpang/acme.sh</code></pre><p>安装很简单, 一个命令:</p><pre class=" language-shell"><code class="language-shell">curl https://get.acme.sh | sh</code></pre><p>并且acme.sh 支持大多数国内知名dns的api方式。比如dnspod,aliyun，只需要在相应的平台上申请id和key即可使用api方式使用acme.sh，非常方便，申请证书一条命令就搞定了。<br>以下命令使用dnspod的api方式申请easex.cn泛域名证书，其下的所有子域名均可以使用。</p><pre class=" language-shell"><code class="language-shell">acme.sh --issue -d easex.cn -d *.easex.cn --dns dns_dp</code></pre><p>申请到的证书默认存放在 当前用户的 <code>~/.acme.sh/easex.cn（域名）</code>目录下。你可以copy出来，或者使用 acme.sh的install-cert命令来安装到指定目录。</p><h3 id="nginx的配置"><a href="#nginx的配置" class="headerlink" title="nginx的配置"></a>nginx的配置</h3><p>nginx的安装就不说了，在centos下通常用yum 来安装，也可以自己编译。这里只说配置一事。网上虽然有很多关于http跳转https的配置，但都只针对单域名的，对泛域名都无法使用。<br>以下是本人使用着的配置，供大家参考。</p><pre class=" language-conf"><code class="language-conf">upstream tomcat9 { server 127.0.0.1:8080;}server { listen 80; server_name *.easex.cn; return 301 https://$http_host$request_uri;}server { listen 443 ssl http2; server_name *.easex.cn; ssl_certificate cert/easex.cn/fullchina.cer; ssl_certificate_key cert/easex.cn/easex.cn.key; ssl_session_timeout 5m; ssl_protocols TLSV1 TLSv1.1 TLSv1.2; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_prefer_server_ciphers on; access_log logs/easex.cn_access.log; error_log logs/easex.cn_error.log; location / { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; proxy_pass http://tomcat9/; }}</code></pre><p>这里的server_name均指定的为 <code>*.easex.cn</code> ，重点就在于 <code>return 301 https://$http_host$request_uri;</code> 这一句。在这里不得不提一下不管是使用$host还是$server_name，都不能让浏览器正常跳转到相应的子域名，只有使用$http_host这样才可以，困绕了我两天时间。<br>通过以上配置，80端口被强制跳转到了443，但443中通过 <code>proxy_pass http://tomcat9/;</code>实际还是跳转回了http的原始端口，但对外，浏览器和用户所看到的确实是https了，并且显示的是安全网站。</p><h3 id="注意事项"><a href="#注意事项" class="headerlink" title="注意事项"></a>注意事项</h3><p>服务器应该要开放 80 443端口。</p>]]></content>

<content type="html"><![CDATA[<h2 id="SpringBoot-JdbcTemplate通用Mapper的实现"><a href="#SpringBoot-JdbcTemplate通用Mapper的实现" class="headerlink" title="SpringBoot+JdbcTemplate通用Mapper的实现"></a>SpringBoot+JdbcTemplate通用Mapper的实现</h2><p>就我个人而言, 使用某个框架, 还是建议尽是只使用框架原生提供的方法来完成相关的操作, 这样从各方面来说应该都是性能最优的. 代码也应该是最好阅读和理解的. 这里还用上一篇中的model来说明. 各位也可以对两篇进行一下对比, 看看哪一种更适合你.</p><h3 id="通用Mapper"><a href="#通用Mapper" class="headerlink" title="通用Mapper"></a>通用Mapper</h3><pre class=" language-java"><code class="language-java"><span class="token
