springdata+redis配置详解

springdata设计初衷是位简化数据类型和数据的持久化存储，它并不局限是关系型数据库还是nosql数据库，都提供了简化的数据库连接，让数据获取变得更加的简单。所有这些的实现有统一的api提供。

本文主要设置spring-data-redis的相关配置特性：

1.RedisTemplate:高度封装的，自动连接池管理类;

2.对数据类型进行了归类，封装了操作接口类：

　　a) ValueOperations:key-value操作

　　b) setOperations:set的相关操作

　　c) ZsetOperations:

　　d) HashOperations:hash数据类型操作

　　e) ListOperations:list数据类型操作

3.对事务进行 封装，通过容器进行控制。

4.序列化机制，提供各种序列化策略选择。

 

集成配置详解：

　　1.提供简单封装保存查询操作接口，以及实现类。

public interface RedisCommand {

    public void save(String key,String value);
    
    public String get(String key);
    
    public <T> T getObject(String key,Class<T> clazz);
    
}

@Service
public class RedisHandle implements RedisCommand {

    @Autowired
    protected RedisTemplate<String, String> redisTemplate;

    @Override
    public void save(final String key, final String value) {
        redisTemplate.execute(new RedisCallback<Object>() {
            @Override
            public Object doInRedis(RedisConnection connection)
                    throws DataAccessException {
                connection.set(
                        redisTemplate.getStringSerializer().serialize(
                                "user.uid." + key), redisTemplate
                                .getStringSerializer().serialize(value));
                return null;
            }
        });
    }

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

    @Override
    public <T> T getObject(String key, Class<T> clazz) {
        // TODO Auto-generated method stub
        return null;
    }


}

　　2.业务逻辑类

@Service(value="userRedis")
public class UserRedisImpl implements UserRedis{

    @Autowired
    protected RedisHandle handler;

    @Override
    public void saveUser(final User user) {
        handler.save(user.getId()+"", JSONObject.toJSONString(user));
    }

    @Override
    public User getUser(final long id) {
       String value =handler.get(id+"");
       User u= JSONObject.parseObject(value, User.class);
       return u;
    }
}

　　3.测试类：

public class TestUseRedis {

    @SuppressWarnings("resource")
    public static void main(String[] args) {
        ApplicationContext ac =  new ClassPathXmlApplicationContext("classpath:/spring-redis.xml");
        UserRedis userDAO = (UserRedis)ac.getBean("userRedis");
        System.out.println("userDao"+JSONObject.toJSONString(userDAO));
        User user1 = new User();
        user1.setId(4);
        user1.setName("oba2sssss220a");
        userDAO.saveUser(user1);
        User user2 = userDAO.getUser(2);
        System.out.println(user2.getName());
    }
}

　　4.配置文件相关：
