基于轻量级Java EE框架的异常处理研究

正确使用异常处理机制对设计可靠、健壮的程序十分重要。对轻量级框架Struts2、Spring和Hibernate的异常处理进行分析,通过研究数据层、业务层、表现层的异常处理方式,结合异常抛出的种类以及在异常发生时的程序流程控制,提出了Java EE系统开发中,层与层之间异常的声明与处理方式,以及异常信息的包装再处理过程。

Research on Exception Handling in Light-Weight Java EE Framework

The correct operation of the exception handling is important for reliable design and steady program.The paper analyzes the exception treatment for the light-weight framework,Struts2,Spring and Hibernate,and points out the claim and treatment methods among layers in the process of the development of java EE system,and the retreatment process of the installation of the exception information by researching the data layer,the business layer and presentation layer and combining with the exceptional classification and the program process control during the exception.
