首先需要JDK自带的keytool工具生成密钥以及证书 在CMD中输入 keytool -genkey -alias tomcat -keyalg RSA -keystore ./server.keystore来获取一个.keystore文件
输入密钥库口令:123456 再次输入新口令:123456 您的名字与姓氏是什么? [Unknown]: kaibowang 您的组织单位名称是什么? [Unknown]: yuxuelian 您的组织名称是什么? [Unknown]: yuxuelian 您所在的城市或区域名称是什么? [Unknown]: chengdu 您所在的省/市/自治区名称是什么? [Unknown]: chengdushi 该单位的双字母国家/地区代码是什么? [Unknown]: china CN=kaibowang, OU=yuxuelian, O=yuxuelian, L=chengdu, ST=chengdushi, C=china是否正确? [否]: y 输入 <tomcat> 的密钥口令 (如果和密钥库口令相同, 按回车): 再次输入新口令: Warning: JKS 密钥库使用专用格式。建议使用 "keytool -importkeystore -srckeystore C:\Users\Administrator\.keystore -destkeystore C:\Users\Administrator\.keystore -deststoretype pkcs12" 迁移到行业标准格式 PKCS12。打开eclipse，开始设置tomcat，在Window→Preferences→Server→Launching 去掉勾选的Automatically publish when starting servers
然后更改eclipse工作目录中的Server文件夹，里面有个Server.xml（记得先将原来的文件做备份），把内容修改为

接着双击Servers中的tomcat，双击前记得将自己之前导入的项目全部remove，再Server Locations这个选项中选择第二个，这个是我用来做测试，看能否打开tomcat的主页。
最后更改tomcat文件夹中的Conf文件夹下的Server.xml，然后将之前复制到eclipse中的server.xml的内容复制进去。
接着启动项目，遇到报错，认真看控制台中的输出内容，大部分都是端口占用导致的报错，用CMD来查找到底是什么进程占用了端口，例如命令netstat -ano | findstr "8005"" tasklist | findstr "3228" taskkill /f /t /im javaw.exe ，或者直接更改两个server.xml中的端口号，我用的443因为用443可以不需要再输入网址的时候再填写端口号，比较方便。
这样一个项目就成功的从http转成了https
