【摘要】：随着SSH2框架越来越受到程序员的青睐,并且已经成为当今大型应用软件的首选WEB技术。日志记录功能是应用系统不可缺少的一部分,但现有的日志插件不仅与应用程序处于紧耦合状态,而且兼容性较差。同时,市场上缺少针对数据信息的日志插件。所以,开发一款与业务逻辑完全解耦、执行速度快、配置简便的数据日志插件是必不可少的趋势。本课题通过对国内外市场上存在的日志记录框架的分析和研究,在此基础之上,针对将数据日志记录动作与业务逻辑解耦,良好的兼容性,高效的执行性能这些具体需求,创建了数据日志插件应用在SSH2框架上的功能架构,并提出了一个基于SSH2框架开发数据日志插件的研究方案。该方案利用定制Hibernate监听器方式完成了对底层封装的add、update、delete方法拦截,然后使用Spring Aop面向切面编程技术实现获取数据信息的功能,以及提出利用Spring对注解类技术的支持,完成对方法体中原生SQL语句的识别及信息获取,并通过在注解类的输入流中增加双缓冲机制,提高单词分析器的工作效率。在完成数据日志配置方案之后,提出在应用系统加载的初期,通过自定义的初始化类以及单例类实现将用户配置文件读取到内存中,避免了耗时的I/O操作。此外,本课题还提出使用缓冲池技术解决写日志文件时可能遇到的多线程同步问题。最后,在实际的应用系统中应用数据日志插件,通过与已有日志框架的对比分析,验证了数据日志插件的性能优势,并总结了数据日志插件具有的特性。在数据日志插件的实际应用过程中,它具有业务逻辑无关和日志记录逻辑独立两方面的突出优点。前者是指将日志记录与业务逻辑完全解耦,后者指插件的功能独立、针对性强。此外,数据日志插件的引用及配置方法简单,易于使用。
[Abstract]:With the increasing popularity of the SSH2 framework, it has become the preferred WEB technology for large applications. Logging is an indispensable part of the application system, but the existing logging plug-in is not only tightly coupled with the application, but also has poor compatibility. At the same time, there is a lack of logging plug-ins for data information on the market. Therefore, the development of a completely decoupled business logic, fast execution, easy configuration of data logging plug-in is an essential trend. Based on the analysis and research of the logging framework in the domestic and foreign markets, this paper aims at the specific requirements of decoupling the data logging actions from the business logic, good compatibility, and efficient execution performance. The functional framework of data log plug-in applied on SSH2 framework is established, and a research scheme of developing data log plug-in based on SSH2 framework is proposed. This scheme uses the custom Hibernate listener to intercept the add-on update delete method of the underlying encapsulation, then realizes the function of obtaining data information by using the Spring Aop face oriented programming technology, and proposes the support of the annotated class technology by using Spring. The recognition and information acquisition of the native SQL statements in the body of the method are completed, and the efficiency of the word analyzer is improved by adding a double buffer mechanism to the input stream of the annotation class. After the data log configuration scheme is completed, it is proposed that in the initial stage of application system loading, the user profile can be read into memory through custom initialization class and singleton class to avoid the time-consuming I / O operation. In addition, this paper also proposes to use buffer pool technology to solve the problem of multithread synchronization when writing log files. Finally, the data log plug-in is applied in the practical application system. The performance advantages of the data log plug-in are verified by comparing the data log plug-in with the existing log framework, and the characteristics of the data log plug-in are summarized. In the practical application of data log plug-in, it has two outstanding advantages: business logic independence and logging logic independence. The former refers to the complete decoupling of logging and business logic, while the latter refers to the independent function and strong pertinence of the plug-in. In addition, the data log plug-in reference and configuration method is simple, easy to use.
