clover icon clover

clover 1、开发server和client端 定时向zk集群发送心跳数据包,利用Java自带的timer程序实现该功能 2、开发整天的monitor程序,用来定时向zk中获取server和client端的心跳数据信息,如果超过指定时间没有收到最新的数据包,那么任务server端或者client端死掉了,此时要删除该server或client端节点,发邮件通知相关人员,记录异常日志到系统日志文件和MongoDB中 3、client端接受创建job请求,将job信息创建到client服务端,并根据job时间规则运行,并将任务信息存储到MongoDB中 4、当client端job运行时候,封装执行任务信息,发送到指定客户端机器,更新client端job执行时间和状态,如不在需要继续运行,那删除job并从MongoDB中删除相关任务信息 5、client端接受删除job请求,client服务端,立即执行删除job并将任务信息从MongoDB中删除 6、client端接受更新job请求,client服务端,立即执行删除job并创建新job,并将任务信息从MongoDB中删除,然后再存储新job信息 7、第一版 使用Netty做消息通讯中间件,存储消息放入Redis中,服务器开启Http请求,客户端 通过 发送Http请求到服务器来处理请求,由于任务太多 redis处理能力不行,放弃该方案 第二版 使用Netty RPC框架,自己开发一个Server端和Client,各种启动指定端口,由于 必须要求Server端和Client必须启动才能进行消息发送,所以感觉非常不灵活,因为放弃该方案 第三版 使用架构组推荐的rocketmq,通过使用发现,很严重问题,消息会重复发送,经常会收到重复的消息,在测试的时候发现,经常发生消息异常和报错,跟架构组刘婷峰沟通说,可能是机器性能不行了,他也不知道具体原因,感觉非常不靠谱,果断放弃 第四版 使用 zeromq,通过在网上查资料,对比各种mq后,发现zeromq是最轻量级,出现消息是最快的,经过测试完全能满足业务,果断使用 8、由于项目中使用zk,自己开发zk使用工具类,定制server端增删改查zk消息以及定制client端增删改查zk消息,功能测试zk,目前打算增加zk watch功能 9、开发server和client端 定时向zk集群发送心跳数据包,利用Java自带的timer程序实现该功能 10、开发整天的monitor程序,用来定时向zk中获取server和client端的心跳数据信息,如果超过指定时间没有收到最新的数据包,那么任务server端或者client端死掉了,此时要删除该server或client端节点,发邮件通知相关人员,记录异常日志到系统日志文件和MongoDB中 11、开发console控制台管理,可以查看任务动态运行状态和次数信息 12、zk管理页面,查看server和client端节点信息,更新和删除节点信息 13、job管理页面,查看job详细信息 14、联系人管理页面,增删改查联系人信息 15、log日志管理页面,根据系统报错记录的日志信息,在页面中可以详细查看

indexmaker icon indexmaker

IndexMaker is a tool I made while working at Fuji Film Graphics Systems. The tool makes use of the Java version of the IText library for PDF processing. In order to integrate maintenance guide PDF files for Fuji Film products with an existing instruction manual, a new table of contents had to be created to reflect new page numbering. In addition each item in the table of contents had to properly link to the first page of the supplemented maintenance manual. Since this was a frequent and time consuming task to do by hand (and it requires purchase of Adobe Acrobat standard), I created this tool to automate the process.
