1、pom.xml添加依赖包
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-redis</artifactId> <version>1.3.2.RELEASE</version> </dependency>
2、在application.properties中配置redis:
# REDIS (RedisProperties) # Redis数据库索引(默认为0) spring.redis.database=0 # Redis服务器地址 spring.redis.host=localhost # Redis服务器连接端口 spring.redis.port=6379 # Redis服务器连接密码(默认为空) spring.redis.password= # 连接池最大连接数(使用负值表示没有限制) spring.redis.pool.max-active=8 # 连接池最大阻塞等待时间(使用负值表示没有限制) spring.redis.pool.max-wait=-1 # 连接池中的最大空闲连接 spring.redis.pool.max-idle=8 # 连接池中的最小空闲连接 spring.redis.pool.min-idle=0 # 连接超时时间(毫秒) spring.redis.timeout=0
3、配置类:
@Configuration public class RedisConfig { @Bean JedisConnectionFactory jedisConnectionFactory() { return new JedisConnectionFactory(); } @Bean public RedisTemplate<String, Primary> redisTemplate(RedisConnectionFactory factory) { RedisTemplate<String, Primary> template = new RedisTemplate<String, Primary>(); template.setConnectionFactory(jedisConnectionFactory()); template.setKeySerializer(new StringRedisSerializer()); template.setValueSerializer(new RedisObjectSerializer()); return template; } }
public class RedisObjectSerializer implements RedisSerializer<Object> { private Converter<Object, byte[]> serializer = new SerializingConverter(); private Converter<byte[], Object> deserializer = new DeserializingConverter(); static final byte[] EMPTY_ARRAY = new byte[0]; public Object deserialize(byte[] bytes) { if (isEmpty(bytes)) { return null; } try { return deserializer.convert(bytes); } catch (Exception ex) { throw new SerializationException("Cannot deserialize", ex); } } public byte[] serialize(Object object) { if (object == null) { return EMPTY_ARRAY; } try { return serializer.convert(object); } catch (Exception ex) { return EMPTY_ARRAY; } } private boolean isEmpty(byte[] data) { return (data == null || data.length == 0); } }
4、添加controller类测试:
@RestController @RequestMapping(value="redisprimary") public class PrimaryController { @Autowired PrimaryRepository repository; @Autowired private StringRedisTemplate stringRedisTemplate; @Autowired private RedisTemplate<String, Primary> redisTemplate; @RequestMapping("getall") public List<Primary> getAll(){ stringRedisTemplate.opsForValue().set("stringset", "111"); System.out.println(stringRedisTemplate.opsForValue().get("stringset")); System.out.println(redisTemplate.opsForValue().get("yy")); List<Primary> primaryList=repository.findAll(); for (Primary p:primaryList){ System.out.println(p); } Primary primary=primaryList.get(0); redisTemplate.opsForValue().set("yy", primary); System.out.println(primary); System.out.println(redisTemplate.opsForValue().get("yy")); return primaryList; } }
5、注意:
因为向redis保存对象,需要对象时序列化对象,故需要实现接口Serializable。
运行项目测试的时候,必须启动redis
