//測試類
// 生成激活碼
public static void main(String[]args){
            // 發送一封激活郵件
        // 生成激活碼
        String activecode = RandomStringUtils.randomNumeric(32);

        // 將激活碼保存到redis，設置24小時失效
        redisTemplate.opsForValue().set(model.getTelephone(), activecode, 24,
                TimeUnit.HOURS);

        // 調用MailUtils發送激活郵件
        String content = "尊敬的客戶您好，請於24小時內，進行郵箱賬戶的綁定，點擊下面地址完成綁定:<br/><a href='"
                + MailUtils.activeUrl + "?telephone=" + model.getTelephone()
                + "&activecode=" + activecode + "'>綁定地址</a>";
        MailUtils.sendMail("激活郵件", content, model.getEmail());
}

//pom文件導入座標
<!-- 郵件發送工具 -->
        <dependency>
            <groupId>javamail</groupId>
            <artifactId>mail</artifactId>
            <version>1.3.2</version>
        </dependency>

        <dependency>

            <artifactId>xbean-spring</artifactId>
            <version>3.7</version>
        </dependency>

導入maven座標

        <!-- 郵件發送工具 -->
        <dependency>
            <groupId>javamail</groupId>
            <artifactId>mail</artifactId>
            <version>1.3.2</version>
        </dependency>

方法調用

MailUtils.sendMail("標題", "正文", "接收郵箱號");
