D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:逃跑的野狐掳走了莉迪亚，艾伦掏出苍蝇治好了艾萨克和双胞胎，但双胞胎狼人在寻找莉迪亚的时候中了埋伏，被含有附子草的子弹打伤，幸亏德里克赶来救走二人。众人得知野狐将莉迪亚囚禁在已废弃的集中营里，基拉的母亲带领鬼武士先行赶去，斯科特和艾萨克随后路赶去，但野狐竟然夺取了鬼武士的控制权。众人与鬼武士大战，艾莉森为救重伤的艾萨卡被鬼武士一剑穿胸，死在斯科特怀里。众人因艾莉森身亡陷入悲痛中，而野狐却带领鬼武士进攻警局和医院，掀起血腥大屠杀，斯科特众人迎战鬼武士陷入苦战。艾萨克发现银箭头能杀死鬼武士，与阿金斯赶赴救援杀光鬼武士，让斯科特与基拉杀掉野狐。但是德里克却告知斯泰尔斯凯莉姑姑竟然变成狼人再次归来。Momay是一个在网上杂志上撰写热门短篇小说的年轻女作家，看起来像25岁般，实际上她是2000岁的不老女人。在这漫长岁月间，因她被诅咒而不老不死。她曾不断想要尝试死去，但都未能成功。有一天，有人告诉她，只有找到真爱，她才可以回归生老病死的循环。为了寻找真爱，Momay与四个潜在的真爱男子开始发展关系，找出她命中的真命天子。必定涉及朝廷各部及各地州府，万万疏忽不得。The following settings interfaceBefore performing an SSL data transfer, Both sides of the communication must first shake hands with SSL, The encryption algorithm has been negotiated to exchange the encryption key, Perform identity authentication, Normally, This SSl handshake process only needs to be performed once, But there is a Regegotiation option in the SSL protocol, It allows renegotiation of the secret key to create a new key, The attacker repeatedly carries out the key renegotiation process, and the key renegotiation process requires the server to invest 15 times more CPU computing resources than the client. In addition, even if the server does not support Renegotiation, the attacker can still create similar attack effects by opening a new SSL connection separately.
