spring boot集成redis

 第一步：添加maven依赖

                
		    org.springframework.boot
		    spring-boot-starter-data-redis
		

第二步：配置applicaiton.properties文件

#redis的ip地址
spring.redis.host = localhost
spring.redis.port = 6379
spring.redis.timeout = 1000
#默认为空
spring.redis.password=

第三步：RedisConfig的java配置

import java.lang.reflect.Method;

import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;

import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{

	/* 设置生成key的策略 */
	@Bean
	public KeyGenerator keyGenerator() {
		return new KeyGenerator() {
			@Override
			public Object generate(Object target, Method method, Object... params) {
				StringBuilder sb = new StringBuilder();
				sb.append(target.getClass().getName());
				sb.append(method.getName());
				for (Object obj : params) {
					sb.append(obj.toString());
				}
				return sb.toString();
			}
		};
	}
	/* 管理缓存  */
	@Bean
	public CacheManager cacheManager(RedisTemplate redisTemplate) {
		RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
		return rcm;
	}
	/* 配置 RedisTemplate */
	@Bean
	public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
		StringRedisTemplate template = new StringRedisTemplate(factory);
		Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
		ObjectMapper om = new ObjectMapper();
		om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
		om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
		jackson2JsonRedisSerializer.setObjectMapper(om);
		template.setValueSerializer(jackson2JsonRedisSerializer);
		template.afterPropertiesSet();
		return template;
	}
}

第四步：编写redis的服务类

@Service
public class RedisService {
	@Autowired
	private RedisTemplate redisTemplate;
	/**
	 * 写入缓存
	 * 
	 * @param key
	 * @param value
	 * @return
	 */
	public boolean set(final String key, Object value) {
		boolean result = false;
		try {
			ValueOperations operations = redisTemplate.opsForValue();
			operations.set(key, value);
			result = true;
		} catch (Exception e) {
			e.printStackTrace();
		}
		return result;
	}
	/**
	 * 写入缓存设置时效时间
	 * 
	 * @param key
	 * @param value
	 * @return
	 */
	public boolean set(final String key, Object value, Long expireTime) {
		boolean result = false;
		try {
			ValueOperations operations = redisTemplate.opsForValue();
			operations.set(key, value);
			redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
			result = true;
		} catch (Exception e) {
			e.printStackTrace();
		}
		return result;
	}
	/**
	 * 批量删除对应的value
	 * 
	 * @param keys
	 */
	public void remove(final String... keys) {
		for (String key : keys) {
			remove(key);
		}
	}
	/**
	 * 批量删除key
	 * 
	 * @param pattern
	 */
	public void removePattern(final String pattern) {
		Set keys = redisTemplate.keys(pattern);
		if (keys.size() > 0)
			redisTemplate.delete(keys);
	}
	/**
	 * 删除对应的value
	 * 
	 * @param key
	 */
	public void remove(final String key) {
		if (exists(key)) {
			redisTemplate.delete(key);
		}
	}
	/**
	 * 判断缓存中是否有对应的value
	 * 
	 * @param key
	 * @return
	 */
	public boolean exists(final String key) {
		return redisTemplate.hasKey(key);
	}
	/**
	 * 读取缓存
	 * 
	 * @param key
	 * @return
	 */
	public Object get(final String key) {
		ValueOperations operations = redisTemplate.opsForValue();
		return operations.get(key);
	}
	/**
	 * 哈希 添加
	 * 
	 * @param key
	 * @param hashKey
	 * @param value
	 */
	public void hmSet(String key, Object hashKey, Object value) {
		HashOperations hash = redisTemplate.opsForHash();
		hash.put(key, hashKey, value);
	}
	/**
	 * 哈希获取数据
	 * 
	 * @param key
	 * @param hashKey
	 * @return
	 */
	public Object hmGet(String key, Object hashKey) {
		HashOperations hash = redisTemplate.opsForHash();
		return hash.get(key, hashKey);
	}
	/**
	 * 列表添加
	 * 
	 * @param k
	 * @param v
	 */
	public void lPush(String k, Object v) {
		ListOperations list = redisTemplate.opsForList();
		list.rightPush(k, v);
	}
	/**
	 * 列表获取
	 * 
	 * @param k
	 * @param l
	 * @param l1
	 * @return
	 */
	public List
