测试代码

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class RedisTemplateTest {

    @Autowired
    private RedisTemplate<String, String> redisTemplate;

    @Test
    public void testRedis() {
        // 保存key value
        // 设置30秒失效
        redisTemplate.opsForValue().set("city", "重庆", 30, TimeUnit.SECONDS);

        System.out.println(redisTemplate.opsForValue().get("city"));
    }
}

保存邮件激活码

在用户点击注册时,生成激活码并发送一封激活邮件,

// 发送一封激活邮件
        // 生成激活码
        String activecode = RandomStringUtils.randomNumeric(32);

        // 将激活码保存到redis，设置24小时失效
        redisTemplate.opsForValue().set(model.getTelephone(), activecode, 24, TimeUnit.HOURS);

        // 调用MailUtils发送激活邮件
        String content = "尊敬的客户您好，请于24小时内，进行邮箱账户的绑定，点击下面地址完成绑定:<br/><a href='" + MailUtils.activeUrl + "?telephone="
                + model.getTelephone() + "&activecode=" + activecode + "'>绑定地址</a>";
        MailUtils.sendMail("激活邮件", content, model.getEmail());
