如何将Javaweb工程的访问协议由http改为https及通过域名访问?
<p>将javaweb工程的http访问协议更改为https,需要做一下几部操作：</p><ol>
<li>通过jre生成证书</li>
<li>调整tomcat的配置</li>
<li>调整工程的web.xm配置</li>
</ol>
<p>具体详细过程如下：</p>
<p>一、生成证书</p>
<p> 打开cmd切换到java安装目录的jre目录下 执行下面命令</p>
<p> keytool -genkeypair -alias "tomcat" -keyalg "RSA" -keystore "D:\DevDir\installPackage\tomcat\apache-tomcat-6.0.41\tomcat.keystore" -validity 3650</p>
<p> </p>
<p> 指令详解：<br> 1.-storetype 指定密钥仓库类型 <br> 2.-keyalg 生证书的算法名称，RSA是一种非对称加密算法 <br> 3.-keysize 证书大小 <br> 4.-keystore 生成的证书文件的存储路径 <br> 5.-validity 证书的有效期(单位:天)</p>
<p> //其中-alias是证书的别名, RSA是加密算法, -keystore后是输出证书的路径所在</p>
<p> 然后根据提示操作，直到正确生成凭证为止</p>

<p>如果是练习使用的化整个过程中的密码尽量保持一致，熟悉以后再做相应的调整</p>
<p> </p>
<p>二、配置tomcat</p>
<p> 打开tomcat的server.xml文件，找到下图中的位置，将其调整如图<br> <img src="https://img2018.cnblogs.com/blog/1508950/201907/1508950-20190731100912743-1292326173.png"></p>
<p> 如果是在eclipse中使用tomcat进行测试的化上一步的配置调整为在eclipse中配置如下图 </p>

<p> 打开tomat的tomcat-users.xml文件添加下图中的配置</p>
<p> <img src="https://img2018.cnblogs.com/blog/1508950/201907/1508950-20190731101023138-599743162.png"></p>
<p>三、配置工程中的web.xml文件</p>
<p> 打开web.xml新增配置</p>

<p> 配置完成以后 使用 8443端口访问即可。</p>
<p> 如: https:192.168.30.212:8443</p>
