java redis使用之利用jedis实现redis消息队列Word下载.docx

1、/*byte转对象* param bytes* throws Exceptionpublic static Object bytesToObject（byte bytes） throws ExceptionByteArrayInputStream in = new ByteArrayInputStream（bytes）;ObjectInputStream sIn = new ObjectInputStream（in）;return sIn.readObject（）;定义一个消息类，主要用于接收消息内容和消息下表的设置。package com.bean;import java.io.Serial

3、d setContent（String content） this.content = content;利用redis做队列，我们采用的是redis中list的push和pop操作；结合队列的特点：只允许在一端插入新元素只能在队列的尾部FIFO：先进先出原则redis中lpush（rpop）或rpush（lpop）可以满足要求，而redis中list 里要push或pop的对象仅需要转换成byte即可java采用Jedis进行redis的存储和redis的连接池设置34353637383940414243444546474849505152535455565758596061626364656
