我有一个Spring-Mvc + Spring-Boot项目，我想用Redis管理会话。
我有这个配置：
@Configuration
@EnableRedisHttpSession
public class SessionRepositoryConfig {
@Value("${redis.host}")
private String redisHostName;
@Value("${redis.port}")
private int redisPort;
@Bean
JedisConnectionFactory jedisConnectionFactory() {
JedisConnectionFactory factory = new JedisConnectionFactory();
factory.setHostName(redisHostName);
factory.setPort(redisPort);
factory.setUsePool(true);
return factory;
}
@Bean
@Order(value = 0)
public FilterRegistrationBean sessionRepositoryFilterRegistration(SessionRepositoryFilter springSessionRepositoryFilter) {
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
filterRegistrationBean.setFilter(new DelegatingFilterProxy(springSessionRepositoryFilter));
filterRegistrationBean.setUrlPatterns(Arrays.asList("/*"));
return filterRegistrationBean;
}
@Bean
public CacheManager cacheManager(RedisTemplate redisTemplate) {
RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
cacheManager.setDefaultExpiration(24*60*60);
return cacheManager;
}
@Bean
public RedisTemplate<String,ExpiringSession> redisTemplate(RedisConnectionFactory connectionFactory) {
RedisTemplate<String, ExpiringSession> template = new RedisTemplate<String, ExpiringSession>();
template.setKeySerializer(new StringRedisSerializer());
template.setHashKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new StringRedisSerializer());
template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
template.setConnectionFactory(connectionFactory);
return template;
}
}
当我尝试登录应用程序时，出现此错误：

我不明白这个错误。
我知道它链接到GenericJacksonSerializer，因为如果删除它，错误就会消失。但我需要使用它来获得可读的redis数据库。
我可以更改哪些方法来解决此问题？我试图创建一个自定义的JsonSerializer但没有成功。也许我需要改变另一件事。
