默认情况下,在Rails 3.1(RC1)下,链接在(dev)日志中往往非常冗长:

我想降低冗长程度或完全禁用它.我假设有一种干净的方法来禁用或减少日志记录的详细程度,方法是在ActiveRecord SQL语句中添加一个environment.rb或development.rb类似的配置行config.active_record.logger = nil …

你如何比较两个通用类？

class Entry<K,V>
{
    protected K key;
    protected V value;

    public K getKey() { return key; }
    public V getValue() { return value; }

    public static Comparator KeyComparator = new Comparator()
    {
        public int compare(Object o1, Object o2)
        {
            int key1 = ( (Entry) o1 ).getKey();
            int key2 = ( (Entry) o2 ).getKey();

            if (key1 > key2)
            {
                return 1;
            }
            else if (key1 < key2)
            {
                return -1;
            }
            else
            {
                return 0;
            }
        }
    };
}

我得到以下编译错误:
