二十九 SpringBoot整合Email

以下演示的是简单邮件发送

29.1 加入相关依赖　　　

 1           <dependency>
 2           <groupId>org.springframework.boot</groupId>
 3           <artifactId>spring-boot-starter-web</artifactId>  
 4        </dependency>
 5        
 6        <!-- Email依赖 -->
 7        <dependency>
 8                <groupId>org.springframework.boot</groupId>
 9                <artifactId>spring-boot-starter-mail</artifactId>
10        </dependency>
11        
12        <!-- freemarker的依赖 -->
13        <dependency>
14                <groupId>org.springframework.boot</groupId>
15                <artifactId>spring-boot-starter-freemarker</artifactId>
16        </dependency>

29.2 在全局配置文件中配置相关属性

1 spring.mail.host=smtp.qq.com
2 spring.mail.username=your@qq.com
3 #授权码
4 spring.mail.password=
5 spring.mail.properties.mail.smtp.auth=true
6 spring.mail.properties.mail.smtp.starttls.enable=true
7 spring.mail.properties.mail.smtp.starttls.required=true

 8     
 9     //发送带有附件的邮件
10     public void sendAttachmentMail(String sendTo,String title,String content,File file);
