jedis的创建
1.先启动redis 如果报
那么说明你redis服务器服务器端还没打开
|
1
2
3
4
|
//启动服务端
redis-server /etc/redis.conf
//启动客户端
redis-cli
|
如果启动成功，就是这样
2.创建一个maven工程
导入jedis依赖

|
<dependencies>
<dependency>
<groupid>redis.clients</groupid>
<artifactid>jedis</artifactid>
<version>3.2.0</version>
</dependency>
</dependencies>
|
3.创建一个class

public class jedisdemo1 {
public static void main(string[] args) {
jedis jedis = new jedis("xx.xxx.xx.xx",6379);
//如果redis配置了密码就在这里输入不然会连接失败
jedis.auth("xxxx");
string value = jedis.ping();
system.out.println(value);
}
}
|
如果是第一次连接会很大概率报错
这时候有两种方法第一种是关闭防火墙，但是这种不太好，其实只要开放6379端口连接就可以了

public class phonecode {
public static void main(string[] args) {
verifycode("12345678900");
//校验验证码是否正确
// getrediscode("12345678900","940487");
}
//1.生成六位验证码
public static string getcode(){
random random = new random();
string code = "";
for (int i = 0; i < 6; i++) {
int i1 = random.nextint(10);
code = code +i1;
}
return code;
}
//2.每个手机每天只能发三次，验证码放到redis中，设置过期时间
public static void verifycode(string phone){
//连接redis
jedis jedis = new jedis("172.18.17.215",6379);
jedis.auth("1052600676");
//先自定义两个key，从而通过后面步骤给key赋一个value
//手机发送次数
string countkey = phone+"count";
//验证码key
string codekey = phone + "code";
//每个手机每天只能发送三次
//通过key查看是否有value
string count = jedis.get(countkey);
if (count == null){
//没有发送次数，说明是第一次发送，那就设置发送次数为1
jedis.setex(countkey,24*60*60,"1");
}else if (integer.parseint(count) <= 2){
jedis.incr(countkey);
}else if (integer.parseint(count) > 2){
system.out.println("验证码超过三次，无法发送");
jedis.close();
return;
}
//设置过期时间
//value
string codee = getcode();
jedis.setex(codekey,120,codee);
jedis.close();
}
//3.验证码校验
public static void getrediscode(string phone,string code){
//连接redis
jedis jedis = new jedis("172.18.17.215",6379);
jedis.auth("1052600676");
//验证码key
string codekey = phone + "code";
string rediscode = jedis.get(codekey);
if (rediscode.equals(code)){
system.out.println("成功");
}else{
system.out.println("失败");
}
jedis.close();
}
}
