mysql+javaWeb+jdbc+tomcat開發中的中文亂碼處理

1.修改工作空間編碼方式為UTF-8

• window-->properties-->General-->Workspace-->Other-->UTF-8 

2.創建的jsp全部修改為UTF-8

• 修改jsp默認編碼方式 window --> preference --> Web --> JSP Files --> Encoding 修改為UTF-8 

3.在doGet()/doPost里面加上以下代碼

request.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=UTF-8"); 

4.對於get方式提交到Servlet的數據，中文亂碼處理請參照下面示例

String username = request.getParameter("username"); username = new String(username.getBytes("ISO-8859-1"),"UTF-8"); 

5.mysql亂碼處理,在原來的URL后面加上?useUnicode=true&characterEncoding=UTF-8

jdbcUrl=jdbc:mysql://localhos:3306/greadManagert?useUnicode=true&characterEncoding=UTF-8 

• 如果在xml中識別不了&符號，要使用實體字符"&amp"加“;”來代替&，即

jdbcUrl=jdbc:mysql://localhos:3306/greadManagert?useUnicode=true&characterEncoding=UTF-8 

6.修改tomcat配置文件server.xml,63行，加上URIEncoding="utf-8"

<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> 

7.配置亂碼過濾器

 <!-- 亂碼過濾器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 

番外篇：自動提示

• window-->preference-->java-->Editor-->Content Assist-->Auto activation triggers for java,在里面把a--z二十六個字母全輸入進去
