Redis快取Mysql模擬使用者登入Java實現例項
一、首先建立兩個類，一個類連線Mysql，一個類連線Redis，並複寫相關方法：
public class Mysql {
public Connection conn;
{
try {
Class.forName("com.mysql.jdbc.Driver");
conn=DriverManager.getConnection("jdbc:mysql://localhost/spring","root","root");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
public class Redis extends Jedis {
public Jedis redis;
{
redis = new Jedis("192.168.217.128", 6379);
redis.auth("root");
}
// public static void main(String[] args) {
// System.out.println(redis.get("name"));
// System.out.println(redis.keys("*"));
// // redis.sinter(keys);
// }
public String get(String key) {
return redis.get("name");
}
public String set(String key, String value) {
return redis.set(key, value);
}
public Long del(String... keys) {
return redis.del(keys);
}
// 鍵值增加字元
public Long append(String key, String str) {
return redis.append(key, str);
}
public Boolean exists(String key) {
return redis.exists(key);
}
// Need research
public Long setnx(String key, String value) {
return redis.setnx(key, value);
}
public String setex(String key, String value, int seconds) {
return redis.setex(key, seconds, value);
}
public Long setrange(String key, String str, int offset) {
return redis.setrange(key, offset, str);
}
public List<String> mget(String... keys) {
return redis.mget(keys);
}
public String mset(String... keys) {
return redis.mset(keys);
}
public Long msetnx(String... keysvalues) {
return redis.msetnx(keysvalues);
}
public String getset(String key, String value) {
return redis.getSet(key, value);
}
public String hmset(String key, Map<String, String> hash) {
return redis.hmset(key, hash);
}
public Map<String, String> hgetall(String key) {
return redis.hgetAll(key);
}
public String hget(final String key, final String field) {
return redis.hget(key, field);
}
public Long hset(final String key, final String field, final String value) {
return redis.hset(key, field, value);
}
public Long expire(final String key, final int seconds) {
return redis.expire(key, seconds);
}
public Boolean hexists(final String key, final String field) {
return redis.hexists(key, field);
}
}
