y.equals(x)也必须返回true)、传递性(x.equals(y)和y.equals(z)都返回true时,x.equals(z)也必须返回true)和一致性(当x和y引用的对象信息没有被修改时,多次调用x.equals(y)应该得到同样的返回值),而且对于任何非null值的引用x,x.equals(null)必须返回false。

当readOnly="true"时,表示二级缓存返回给所有调用者同一个缓存对象实例,调用者可以update获取的缓存实例,但是这样可能会造成其他调用者出现数据不一致的情况(因为所有调用者调用的是同一个实例)。当readOnly=“false”时,返回给调用者的是二级缓存总缓存对象的拷贝,即不同调用者获取的是缓存对象不同的实例,这样调用...
