JSP技術廣泛應用于動態網頁制作，但在應用中文字符時常常出現亂碼。以前有關JSP技術中文亂碼的研究，只是側重于對常見的幾種中文亂碼情況分析，并從網頁代碼方面進行研究，然后給出相應的代碼，缺少對造成中文亂碼原因的研究。本文從造成亂碼的根本原因入手進行分析，以JSP技術工作過程為線索，提出新的研究思路：從開發Java程序時所涉及的開發環境以及使用的開發工具著手，研究字符的存儲與編碼的關系，將影響Java中字符編碼的原因分為內因和外因。研究結果表明，在使用JSP技術的過程中，中文字符的編碼不僅在JSP工作過程中，會發生編碼的轉換，而且會因開發環境以及使用開發工具不同，使存儲在內存的編碼形式發生轉換，每種編碼之間的轉換沒有規律。本文系統地分析了Java中字符編碼的轉換，最后針對JSP中常見的中文亂碼情況，給出了相應的解決方法。

Abstract:

?JSP technology is widely used in the production of dynamic web pages， but the chinese characters in its application often garbled. Chinese garbled before the JSP technology research， is focused on several common chinese garbled on the situation analysis， and researches aspects of the code from the page， and then gives the corresponding code， the lack of research into the reasons causes the chinese garbled. This paper analyses from the real causes of the underlying cause garbled. JSP technology researches to the work process for the clues， puts forward new research ideas： the development of Java programs involved in the development environment and start using the development tools， storage and encoding of character relationships， affecting the character encoding in Java is divided into internal and external reasons. The results show that use of JSP technology in the process， the chinese character code in the JSP course of their work not only will happen coding of the convert， but also because of development environment， and use the development tools， the code stored in memory in different forms. Between each code conversion is not the law. This paper systematically analysed the Java character encoding conversion， in the end for the JSP common situation in the chinese garbled， the corresponding solution was given.
