(入门SpringBoot)SpringBoot发送邮件(十一)

springboot配置邮件服务:

1.引入jar

<!-- 邮件 -->

<dependency>
    <groupid>org.springframework.boot</groupid>
    <artifactid>spring-boot-starter-mail</artifactid>
</dependency>

2.配置资源文件,邮箱参数:

#邮件:邮件服务器
spring.mail.host=smtp.163.com
#发件人邮箱
spring.mail.username=xxx@163.com
#授权码:
spring.mail.password=abc123
#编码:
spring.mail.default-encoding=utf-8

3.准备发送邮件方法:

service层读取配置文件参数,注入javamailsender

@value("${spring.mail.username}")
private string sender; //读取配置文件中的参数
@autowired
private javamailsender mailsender; //自动注入的bean

/**
 * 发送普通文本:
 * @param to 发送人:
 * @param subject 发送标题:
 * @param context  发送内容:
 */
@override
public void sendsimplemail(string to, string subject, string context) {
    simplemailmessage message = new simplemailmessage();
    message.setfrom(sender);
    message.setto(to);
   message.setsubject(subject);
   message.settext(context);
   mailsender.send(message);

}

/**
 * 发送html:
 * @param to 发送人:
 * @param subject 发送标题:
 * @param context  发送内容:
 */
@override
public void sendsimplemailhtml(string to, string subject, string context) {
    mimemessage message = null;
    try {
        message = mailsender.createmimemessage();
        mimemessagehelper helper = new mimemessagehelper(message, true);
        helper.setfrom(sender);
        helper.setto(to);
        helper.setsubject("标题：发送html内容");

        stringbuffer sb = new stringbuffer();
        sb.append("<h1>大标题-h1</h1>")
                .append("<p style='color:#f00'>红色字</p>")
                .append("<p style='text-align:right'>右对齐</p>");
        helper.settext(sb.tostring(), true);
    } catch (exception e) {
        e.printstacktrace();
    }
    mailsender.send(message);
}
