1. 引入依赖
<parent>

<relativePath/> <!-- lookup parent from repository -->

</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

2. application.yml中添加配置
spring:
redis:
#数据库索引
database: 0
host: 127.0.0.1
port: 6379
password:
jedis:
pool:
#最大连接数
max-active: 8
#最大阻塞等待时间(负数表示没限制)
max-wait: -1
#最大空闲
max-idle: 8
#最小空闲
min-idle: 0
#连接超时时间
timeout: 10000
3. RedisConfiguration
@Configuration
@EnableCaching
public class RedisConfiguration extends CachingConfigurerSupport {
@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();
}
};
}
// @Bean
// public CacheManager cacheManager(RedisTemplate redisTemplate) {
// RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
// return redisCacheManager;
// }
//
//
// @Bean
// public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
// ////解决键、值序列化问题
// 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;
// }
/*
spring-data-redis 版本不同，方法也不一样
上面是1.5
下面是2.0
*/
@Bean
public CacheManager cacheManager(RedisConnectionFactory connectionFactory) {
RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory).build();
return redisCacheManager;
}
/**
* @Description: 防止redis入库序列化乱码的问题
* @return 返回类型
* @date 2018/4/12 10:54
*/
@Bean
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
redisTemplate.setConnectionFactory(redisConnectionFactory);
redisTemplate.setKeySerializer(new StringRedisSerializer());//key序列化
redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Object.class)); //value序列化
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
4. RedisService
@Component
public class RedisService<HK, V> {
// 在构造器中获取redisTemplate实例, key(not hashKey) 默认使用String类型
private RedisTemplate<String, V> redisTemplate;
// 在构造器中通过redisTemplate的工厂方法实例化操作对象
private HashOperations<String, HK, V> hashOperations;
private ListOperations<String, V> listOperations;
private ZSetOperations<String, V> zSetOperations;
private SetOperations<String, V> setOperations;
private ValueOperations<String, V> valueOperations;
// IDEA虽然报错,但是依然可以注入成功, 实例化操作对象后就可以直接调用方法操作Redis数据库
@Autowired
public RedisService(RedisTemplate<String, V> redisTemplate) {
this.redisTemplate = redisTemplate;
this.hashOperations = redisTemplate.opsForHash();
this.listOperations = redisTemplate.opsForList();
this.zSetOperations = redisTemplate.opsForZSet();
this.setOperations = redisTemplate.opsForSet();
this.valueOperations = redisTemplate.opsForValue();
}
public void hashPut(String key, HK hashKey, V value) {
hashOperations.put(key, hashKey, value);
}
public Map<HK, V> hashFindAll(String key) {
return hashOperations.entries(key);
}
public V hashGet(String key, HK hashKey) {
return hashOperations.get(key, hashKey);
}
public void hashRemove(String key, HK hashKey) {
hashOperations.delete(key, hashKey);
}
public Long listPush(String key, V value) {
return listOperations.rightPush(key, value);
}
public Long listUnshift(String key, V value) {
return listOperations.leftPush(key, value);
}
public List<V> listFindAll(String key) {
if (!redisTemplate.hasKey(key)) {
return null;
}
return listOperations.range(key, 0, listOperations.size(key));
}
public V listLPop(String key) {
return listOperations.leftPop(key);
}
public void setValue(String key, V value) {
valueOperations.set(key, value);
}
public void setValue(String key, V value, long timeout) {
ValueOperations<String, V> vo = redisTemplate.opsForValue();
vo.set(key, value, timeout, TimeUnit.MILLISECONDS);
}
public V getValue(String key) {
return valueOperations.get(key);
}
public void remove(String key) {
redisTemplate.delete(key);
}
public boolean expire(String key, long timeout, TimeUnit timeUnit) {
return redisTemplate.expire(key, timeout, timeUnit);
}
5. test
@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {
@Autowired
RedisService redisService;
@Test
public void findAllUsers() {
redisService.setValue("key","hello");
}
@Test
public void findAllUsers2() {
System.out.println("get key value:"+ redisService.getValue("key"));
}
}
说明
- 以上是具体的配置，如果没有引入redis.clients.jedis 依赖，则会报No beans of 'RedisConnectionFactory' type found.
版本则2.9.0 如果 版本低，则会报其它错误
- spring-data-redis 这个版本分为 1.x 和 2.x 版本变动挺多，不同版本方法也不一样
