在spring mvc项目中使用@CachePut,但是在redis中获取key和value两个单独的数据

Use @CachePut in springmvc project,but get the key and the value two separate data in redis

在spring MVC项目中,我尝试用@CachePut缓存数据,但在redis中,键和值有两个独立的数据: 同时对springboot工程做了同样的操作,得到了正常的结果: springmvc项目中的配置:

<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxTotal" value="${spring.redis.pool.maxTotal}"></property>
    <property name="maxIdle" value="${spring.redis.pool.maxIdle}"></property>
    <property name="minIdle" value="${spring.redis.pool.minIdle}"></property>
    <property name="maxWaitMillis" value="${spring.redis.pool.maxWait}"></property>
</bean>

<bean id="connectionFactory"
      class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    <property name="poolConfig" ref="poolConfig"></property>
    <property name="hostName" value="${spring.redis.host}"></property>
    <property name="port" value="${spring.redis.port}"></property>
    <property name="password" value="${spring.redis.password}"></property>
    <property name="database" value="${spring.redis.database}"></property>
    <property name="timeout" value="${spring.redis.timeout}"></property>
</bean>

<bean id="redisCacheManager" class="org.springframework.data.redis.cache.RedisCacheManager">
    <constructor-arg name="redisOperations" ref="redisTemplate" />
</bean>

<bean class="redis.clients.jedis.JedisPool">
    <constructor-arg ref="poolConfig"/>
    <constructor-arg value="${spring.redis.host}"/>
    <constructor-arg type="int" value="${spring.redis.port}"/>
    <constructor-arg type="int" value="${spring.redis.timeout}"/>
    <constructor-arg type="java.lang.String" value="${spring.redis.password}"/>
    <constructor-arg type="int" value="${spring.redis.database}"/>
</bean>

@Bean
public RedisTemplate<String , Object> redisTemplate(RedisConnectionFactory connectionFactory) {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(connectionFactory);
    Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);

    ObjectMapper mapper = new ObjectMapper();
    JavaTimeModule javaTimeModule = new JavaTimeModule();

    javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(properties.dateFormatter()));
    javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(properties.timeFormatter()));
    javaTimeModule.addSerializer(YearMonth.class, new YearMonthSerializer(properties.yearMonthFormatter()));
    javaTimeModule.addSerializer(MonthDay.class, new MonthDaySerializer(properties.monthDayFormatter()));
    javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(properties.dateTimeFormatter()));
    javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer(properties.dateFormatter()));
    javaTimeModule.addDeserializer(LocalTime.class, new LocalTimeDeserializer(properties.timeFormatter()));
    javaTimeModule.addDeserializer(YearMonth.class, new YearMonthDeserializer(properties.yearMonthFormatter()));
    javaTimeModule.addDeserializer(MonthDay.class, new MonthDayDeserializer(properties.monthDayFormatter()));
    javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(properties.dateTimeFormatter()));
    mapper.registerModule(javaTimeModule);
    mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    serializer.setObjectMapper(mapper);
    template.setKeySerializer(new StringRedisSerializer());
    template.setValueSerializer(serializer);
    template.afterPropertiesSet();
    return template;
}

是不是配置有问题?

RedisCacheManager中,属性usePrefix默认值为false,所以我们应该在JavaConfig中设置usePrefix=true

@Bean
public RedisCacheManager cacheManager(RedisTemplate<String, Object> redisTemplate) {
    RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
    cacheManager.setUsePrefix(true);
    return cacheManager;
}
