Eeasyexcel生成表格作为附件用RabbitMQ发邮件
需求:
从数据库查出数据,生成excel表格作为附件,用RabbitMQ发邮件
这里采用的的网易邮箱,要去用来发件的邮箱账号的设置里把POP3/SMTP/IMAP服务打开
发邮件的POM包
org.springframework.boot
spring-boot-starter-mail
邮箱配置文件
spring:
#邮箱配置
mail:
host: smtp.163.com
username: [email protected] #用来发邮箱的邮箱账号
password: xxxxxxxxxxxxxx #打开POP3/SMTP/IMAP服务后,网易会给的邮箱密码
port: 465 # 这个端口根据实际情况配置，一般都是465
protocol: smtp # 这里应该是不用改的
test-connection: false
default-encoding: UTF-8
properties:
mail:
# debug: true
smtp:
auth: true
connectiontimeout: 10000
timeout: 10000
writetimeout: 10000
socketFactory:
class: javax.net.ssl.SSLSocketFactory
port: 465
starttls:
enable: true
required: true1.Controller
