第一步：添加maven依赖

                <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>

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 */@Beanpublic KeyGenerator keyGenerator() {return new KeyGenerator() {@Overridepublic 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  */@Beanpublic CacheManager cacheManager(RedisTemplate redisTemplate) {RedisCacheManager rcm = new RedisCacheManager(redisTemplate);return rcm;}/* 配置 RedisTemplate */@Beanpublic RedisTemplate<String, String> 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 {@Autowiredprivate RedisTemplate redisTemplate;/*** 写入缓存* * @param key* @param value* @return*/public boolean set(final String key, Object value) {boolean result = false;try {ValueOperations<Serializable, Object> 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<Serializable, Object> 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<Serializable> 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<Serializable, Object> 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<String, Object, Object> 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<String, Object, Object> hash = redisTemplate.opsForHash();return hash.get(key, hashKey);}/*** 列表添加* * @param k* @param v*/public void lPush(String k, Object v) {ListOperations<String, Object> list = redisTemplate.opsForList();list.rightPush(k, v);}/*** 列表获取* * @param k* @param l* @param l1* @return*/public List<Object> lRange(String k, long l, long l1) {ListOperations<String, Object> list = redisTemplate.opsForList();return list.range(k, l, l1);}/*** 集合添加* * @param key* @param value*/public void add(String key, Object value) {SetOperations<String, Object> set = redisTemplate.opsForSet();set.add(key, value);}/*** 集合获取* * @param key* @return*/public Set<Object> setMembers(String key) {SetOperations<String, Object> set = redisTemplate.opsForSet();return set.members(key);}/*** 有序集合添加* * @param key* @param value* @param scoure*/public void zAdd(String key, Object value, double scoure) {ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();zset.add(key, value, scoure);}/*** 有序集合获取* * @param key* @param scoure* @param scoure1* @return*/public Set<Object> rangeByScore(String key, double scoure, double scoure1) {ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();return zset.rangeByScore(key, scoure, scoure1);}
}

第五步：测试redis

@Controller
@RequestMapping("/redis")
public class RedisController {@Autowiredprivate RedisService redisService;/*** 设置Redis数据* * @param key* @param value* 访问方式为http://localhost:8888/redis/setRedis?key=currentName&value=lisi*/@RequestMapping("/setRedis")@ResponseBodypublic Object setRedis(String key, String value) {redisService.set(key, value);return "SUCCESS";}/*** 根据key删除Redis数据* * @param key* 访问方式为http://localhost:8888/redis/delRedis?key=currentName*/@RequestMapping("/delRedis")@ResponseBodypublic Object delRedis(String key) {redisService.remove(key);return "SUCCESS";}/*** 根据key获取Redis数据* * @param key* 访问方式为http://localhost:8888/redis/getRedis?key=currentName*/@RequestMapping("/getRedis")@ResponseBodypublic Object getRedis(String key) {return redisService.get(key);}
}
