JavaMail 是SUN公司提供给广大Java开发人员的一款邮件发送和接受的一款开源类库，官网地址[https://www.oracle.com/java/technologies/javamail.html][https_www.oracle.com_java_technologies_javamail.html]

## springboot整合JavaMail ##

### 引入依赖包 ###

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-mail</artifactId>
          <version>2.5.0</version>
      </dependency>

### 修改配置文件 ###

我这里使用的是163邮箱

server:
      port: 8080
    spring:
      mail:
        host:  smtp.163.com
        port:
        username: 邮箱
        password: 授权码
        default-encoding: UTF-8
        protocol: smtp

### 代码实现 ###

    			//text是发送的内容
                helper.setText(text, true);
                //发送消息
                javaMailSender.send(mimeMessage);
          
            } catch (MessagingException e) { 
                e.printStackTrace();
            }
