spring-data-redis

I'm attempting to use the Jackson serialization feature of spring-data-redis. I am building a ObjectMapper and using the GenericJackson2JsonRedisSerializer as the serializer for the redisTemplate: @Configuration public class SampleModule { @Bean public ObjectMapper objectMapper() { return Jackson2ObjectMapperBuilder.json() .serializationInclusion(JsonInclude.Include.NON_NULL) // Don’t include null values .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS) //ISODate .build(); } @Bean public RedisTemplate getRedisTemplate(ObjectMapper objectMapper, RedisConnectionFactory

I'm testing Redis with spring-data-redis using repositories like this: public interface CreditCardRepository extends CrudRepository<CreditCard, String>{ List<CreditCard> findByIssuer(String issuer); List<CreditCard> findByCreditNetwork(String creditNetwork); List<CreditCard> findByCreditNetworkAndIssuer(String creditNetwork, String issuer); } Above methods will query over Redis structures like: creditcard:creditNetwork:mastercard creditcard:creditNetwork:visa creditcard:issuer:company1 creditcard:issuer:company2 Right now my CreditCard object contains two attributes (issuer, network and the id

I want to use spring-data-redis to caching data in my spring boot app.But it always says cast exception.I googled for some time but have no ideas.Please help me.thanks,any suggestions are greateful!

I am trying to use spring-data-redis in a spring-boot application to work with redis. I am creating JedisConnectionFactory as follows: RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration(); configuration.setHostName("localhost"); configuration.setPort(6379); JedisConnectionFactory connectionFactory = new JedisConnectionFactory(configuration); It throws the exception: Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.data.repository.config.RepositoryConfigurationSource.getAttribute(Ljava/lang/String;)Ljava/util/Optional; at org.springframework

1.pom.xml引入 demo-base引入 说明： jedis :redis官网对java语言提供支持。可单独使用。 spring-data-redis :spring对jedis集成。 2.配置 在配置在demo-web下 redis.properties: redis.host=127.0.0.1 redis.port=6379 redis.timeout=15000 redis.password= redis.database=2 spring-mvc.xml <!--spring最多加载一个context:property-placeholder--> <!--如果去掉jdbc.properties加载，demo-web启动会提示找不对应变量值--> <context:property-placeholder location="classpath:redis.properties,classpath*:jdbc.properties"/> <!--将spring-redis引入spring中--> <import resource="spring-redis.xml"/> spring-redis.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework

If I have 5 members with scores as follows a - 1 b - 2 c - 3 d - 3 e - 5 ZRANK of c returns 2, ZRANK of d returns 3 Is there a way to get same rank for same scores? Example: ZRANK c = 2, d = 2, e = 3 If yes, then how to implement that in spring-data-redis? Any real solution needs to fit the requirements, which are kind of missing in the original question. My 1st answer had assumed a small dataset, but this approach does not scale as dense ranking is done (e.g. via Lua) in O(N) at least. So, assuming that there are a lot of users with scores, the direction that for_stack suggested is better, in

I use spring-data-redis version 1.7.0.M1,and jedis version 2.8.0 Here is my configuration <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="redisConnectionFactory"></property> <property name="keySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property name="hashKeySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property name="valueSerializer"> <bean class="org.springframework.data.redis.serializer

I'm developing Spring Boot + Redis example. In this example, I've developed some custom methods which pull details based on RoleName. For the below method userRepository.findByRole_RoleName("ADMIN") or userRepository.findByMiddleNameContaining("Li"); , we're getting the below exception. The reference URL: https://docs.spring.io/spring-data/keyvalue/docs/1.2.15.RELEASE/reference/html/ Could anyone please provider pointers ? All the other methods are working fine. But just this method causing the problems. I will post all the required code below for reference. Error: java.lang
