Spring会话不使用自定义RedisTemplate bean

Question

试图将RedisTemplate bean与GenericJackson2JsonRedisSerializer一起使用，但是在调试时我注意到Spring会话使用了不同的RedisTemplate实例。

@Configuration
@EnableRedisHttpSession
public class RedisHttpSessionConfig extends 
    AbstractHttpSessionApplicationInitializer {

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory();
    }

    @Bean
    public RedisTemplate<Object, Object> redisTemplate() {
        final RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());

        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.setConnectionFactory(jedisConnectionFactory());
        return template;
    }

    @Bean
    public HttpSessionEventPublisher httpSessionEventPublisher() {
        return new HttpSessionEventPublisher();
    }

当运行这个时，Spring会话似乎对hashValues使用默认的JdkSerializationRedisSerializer，而不是所需的GenericJackson2JSONRedisSerializer。

你知道我错过了什么吗？

您只需要重写spring会话的默认RedisSerializer，如下所示

@Configuration public class RedisConfig {

@Bean(name="springSessionDefaultRedisSerializer")
public RedisSerializer serializer() {
    return new GenericJackson2JsonRedisSerializer();
}
