java - spring boot 集成redis，出错,求解答

这是application.yml文件内容

config context path to "/" by setting an empty string

server:
port: xxxx

JACKSON

spring:
jackson:

serialization:
  INDENT_OUTPUT: true

jwt:
header: xxxxx
secret: xxxxxx
expiration: xxxxxx

这是RedisConfig 类
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{

@Bean
@Override
public KeyGenerator keyGenerator(){  
    return new KeyGenerator() {  
        @Override  
        public Object generate(Object target, Method method, Object... params) {  
            StringBuilder sb = new StringBuilder();  
            sb.append(target.getClass().getName());  
            sb.append(method.getName());  
            for (Object obj : params) {  
                sb.append(obj.toString());  
            }  
            return sb.toString();  
        }  
    };  

}  

@Bean  
public CacheManager cacheManager(  RedisTemplate redisTemplate) {  
    RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
    //设置缓存过期时间
    // rcm.setDefaultExpiration(60);//秒
    //设置value的过期时间
    /*Map<String,Long> map=new HashMap();
    map.put("userToken",60L);
    rcm.setExpires(map);*/
    return rcm;
}  

@Bean  
public RedisTemplate<String, String> redisTemplate(  
        RedisConnectionFactory factory) {  
    StringRedisTemplate template = new StringRedisTemplate(factory);  
    Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);  
    ObjectMapper om = new ObjectMapper();  
    //om.setVisibility(PropertyAccessor.ALL, JsonFormatTypes.ANY); 
    /*om.setVisibility(forMethod, visibility)
    visibility*/
    om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);  
    jackson2JsonRedisSerializer.setObjectMapper(om);  
    template.setValueSerializer(jackson2JsonRedisSerializer);  
    template.afterPropertiesSet();  
    return template;  
}

}
下面是测试
@RequestMapping("/test")

@Cacheable(value="test")
public String getSessionId(){
redisUtil.set("123", "测试");
System.out.println("进入了方法");
String string= redisUtil.get("123").toString();
return string;
}
