實體類

/** * Aug 29, 2012 */package org.zlex.redis.domain;import java.io.Serializable;/** *  * @author  * @version 1.0 * @since 1.0 */public class User implements Serializable {/** *  */private static final long serialVersionUID = -1267719235225203410L;private String uid;private String address;/** * @return the uid */public String getUid() {return uid;}/** * @param uid *            the uid to set */public void setUid(String uid) {this.uid = uid;}/** * @return the address */public String getAddress() {return address;}/** * @param address *            the address to set */public void setAddress(String address) {this.address = address;}}

Dao介面

/** * Aug 29, 2012 */package org.zlex.redis.dao;import org.zlex.redis.domain.User;/** *  * @author  * @version 1.0 * @since 1.0 */public interface UserDao {/** * @param uid * @param address */void save(User user);/** * @param uid * @return */User read(String uid);/** * @param uid */void delete(String uid);}
