关于UTF-8, GB2312 JBoss,JSP,EJB,MySQL,STRUTS的中文解决方案

如果MySQL,J2EE平台的中文处理出现问题，则请从以下几方面考虑：

 A、数据库配置文件my.ini

  [mysqld]

   default-characterset=utf8

   或

   character-set-server=utf8

 B、mysql-ds.xml,以下为部分相关内容

  <?xml version='1.0' encoding='UTF-8'?>

  <datasources>

    <local-tx-datasource>

    <jndi-name>MySqlDS</jndi-name>

    <connection-url>

     jdbc:mysql://localhost:3306/uplatform

    </connection-url>

    <connection-propertyname='characterEncoding'>utf8</connection-property>

    <driver-class>com.mysql.jdbc.Driver</driver-class>

    <user-name>kzz</user-name>

    <password>118200</password>

   ... ... ...

  </datasources>

 C、数据库建表请用utf8为字符集

 D、JSP请用UTF-8或GB2312为编码方式

 E、Java的编码方式请用UTF-8或GB2312

 F、如果使用STRUTS架构，请加载一个Filter，完成UTF－8或GB2312的转换。

 G、tomcat的server.xml中的

          打开tomcat的server.xml文件，找到区块，加入如下一行：

          完整的应如下：

           <Connectorport='8080'

                     maxThreads='150'

                     minSpareThreads='25'

                     maxSpareThreads='75'

                     enableLookups='false'

                     redirectPort='8443'

                     acceptCount='100'

                     debug='0'

                     connectionTimeout='20000'

                     disableUploadTimeout='true'

                     URIEncoding='UTF-8'/>

 H：建议j2ee项目（STRUTS架构）的中文解决：

       所有jsp文件<%@ page language="java"pageEncoding="GB2312"%>

       以（下源码I）中的过滤器采用GB2312

       所有xml文件<?xml version="1.0"encoding="UTF-8"?>

       打开tomcat的server.xml文件，找到区块，加入如下一行：URIEncoding='UTF-8'，具体见G中描述
