Spring Boot Cache – Custom KeyGenerator

I created this kind of a bean to have trully unique keys for caching trough annotations @Cachable, @CachePut etc.

@Bean
    public KeyGenerator keyGenerator() {
        return new KeyGenerator() {
            @Override
            public Object generate(Object o, Method method, Object... objects) {
                // This will generate a unique key of the class name, the method name,
                // and all method parameters appended.
                StringBuilder sb = new StringBuilder();
                sb.append(o.getClass().getName());
                //sb.append(method.getName());
                for (Object obj : objects) {
                    sb.append(obj.toString());
                }
                return sb.toString();
            }
        };
    }
