一、配置環境準備
1.1 mail.smtp.host查看
打開outlook：文件–》信息–》賬戶設置–》雙擊賬戶
1.2 修改本地hosts文件
最好在C:\Windows\System32\drivers\etc\hosts文件配置一下主機名，
ip可以在命令行中 ping mail.unipower.cn 查看到
hosts文件新增一行：
ip mail.unipower.cn
1.3 pom.xml
pom.xml新增依賴：
<!-- mail -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>

- SEQUENCE:2 設置優先級 cance>update>create
取消會議主要是和修改uuid必須一致，主要是以下兩點不一致：
- SEQUENCE:3 設置優先級 cance>update>create
