(1) Basic DescriptionCode as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.Cat Rice Base Attack BonusIn my program, I just started embedded cassandra and used cassandra-driver-core to connect to cassandra, so UDP socket was occupied a lot at once, and redisson needed to initialize its own connection pool when starting, which also needed UDP socket, thus causing this problem.
