User實體類：

public class User {

    private long id;
    private String name;
    
    public long getId() {
        return id;
    }
    
    public void setId(long id) {
        this.id = id;
    }
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
}

UserDAOImpl：

1，spring對dao層的封裝很多用了類似於下面代碼的模板方式。

2，RedisTemplate就是spring對redis的一個封裝而已。

public class UserDAOImpl implements UserDAO {

    @Autowired
    protected RedisTemplate<Serializable, Serializable> redisTemplate;

    public void saveUser(final User user) {
        redisTemplate.execute(new RedisCallback<Object>() {

            @Override
            public Object doInRedis(RedisConnection connection) throws DataAccessException {
                connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getId()),
                               redisTemplate.getStringSerializer().serialize(user.getName()));
                return null;
            }
        });
    }

    @Override
    public User getUser(final long id) {
        return redisTemplate.execute(new RedisCallback<User>() {
            @Override
            public User doInRedis(RedisConnection connection) throws DataAccessException {
                byte[] key = redisTemplate.getStringSerializer().serialize("user.uid." + id);
                if (connection.exists(key)) {
                    byte[] value = connection.get(key);
                    String name = redisTemplate.getStringSerializer().deserialize(value);
                    User user = new User();
                    user.setName(name);
                    user.setId(id);
                    return user;
                }
                return null;
            }
        });
    }

}

測試代碼：

public static void main(String[] args) {
        ApplicationContext ac =  new ClassPathXmlApplicationContext("classpath:/applicationContext.xml");
        UserDAO userDAO = (UserDAO)ac.getBean("userDAO");
        User user1 = new User();
        user1.setId(1);
        user1.setName("obama");
        userDAO.saveUser(user1);
        User user2 = userDAO.getUser(1);
        System.out.println(user2.getName());
    }
