Use a keyGenerator instead, although you wouldn't want a constant key obviously.

   @Cachable(value="TestValue",keyGenerator ="keyGenerator")
    public void method(){

    }

    @Bean
    public KeyGenerator keyGenerator() {
      return new KeyGenerator() {
        @Override
        public Object generate(Object o, Method method, Object... params) {
          return CACHE_KEY ;
        }
      };
    }
