碰到中文问题主要有几类：

1)从confluence的mysql数据库导出的UTF-8数据

2)http get/post请求中汉字

3)ajax xmlhttprequest传递的汉字

4)mysql环境设置

5)spring /velocity /jboss环境的中文配置

成功的文件配置关键内容如下：

1.1spring2应用Web.xml配置

encodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

GB2312

forceEncoding

true

1.2Ibatissqlmap-config.xml

1.3ibatis jdbc配置：

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://127.0.0.1:3306/scmproj?useUnicode=true&characterEncoding=UTF-8

1.4spring mvc:

WEB-INF/velocity/

GB2312

GB2312

text/html;charset=GB2312

false

1

true

templates.vm

org.apache.velocity.runtime.log.SimpleLog4JLogSystem

com.ali

true

true

false

true

.vm

true

true

true

dateTool

由于页面上文字是汉字，但数据库为utf-8。VelocityViewResolver的contentType必须为UTF-8 ,否则部分复杂汉字无法正常显示。如璟。

1.5Mysql5.0创建数据库：

create database scmproj DEFAULT CHARACTER SET utf8;

1.6mysql的配置文件my.ini：

[mysql]

default-character-set=gb2312

[mysqld]

default-character-set=utf8

1.8velocity表单提交前编码

Function GetByteCode(ch)

code = Asc(ch)' -20001

GetByteCode = Hex(code) ' "B1DF"

End Function

String.prototype.urlEncode = function() {

var r = "";

for (var i = 0; i < this.length; i++) {

var code = "" + GetByteCode(this.charAt(i));

if (code.length > 2) {

var b1 = code.substr(0, code.length - 2);

var b2 = code.substr(code.length - 2);

if (i == 0) {

//alert("" + code + ", " + b1 + ", " + code.length + ", " + b2);

}

r += "%" + b1 + "%" + b2;

} else {

r += "%" + code;

}

}

return r;

}

Function checkform()

{

var ōldvalue= document.formtips.content.value;

if(oldvalue=="")

{

alert("请设置值");

return false;

}

var urlEncodeResult=oldvalue.urlEncode();

document.formtips.content.value=urlEncodeResult;

}

1.9接收form表单的服务器端代码

protected ModelAndView onSubmit(HttpServletRequest request,

HttpServletResponse response, Object command, BindException errors)

throws Exception {

try {

SCMTips tips = (SCMTips) command;

if (logger.isInfoEnabled()) {

logger.info("before decode content:" + tips.getContent());

logger.info("requestEncode="+ request.getCharacterEncoding());

}

String decoderesult = java.net.URLDecoder.decode(tips.getContent(),

"gb2312");

if (logger.isInfoEnabled()) {

logger.info("decode result:" + decoderesult);

}

1.10AJAX发送端

functionmakeHttpReq()

{

var new_httpreq = null;

if (window.XMLHttpRequest) {

new_httpreq = new XMLHttpRequest();

if (new_httpreq.overrideMimeType){

new_httpreq.overrideMimeType('text/xml');

}

} else if (window.ActiveXObject) {

try{

new_httpreq = new ActiveXObject("Msxml2.XMLHTTP");

} catch (e) {

try {

new_httpreq = new ActiveXObject("Microsoft.XMLHTTP");

} catch (e) {

}

}

}

returnnew_httpreq;

}

if (httpReq)  {

httpReq.onreadystatechange  =  function(){

if(httpReq.readyState == 4)

{

//var console=document.getElementById('console');

//alert(httpReq.responseText);

//console.innerHtml = httpReq.responseText;

}

};

httpReq.open("GET",   url,   true);

httpReq.setRequestHeader("If-Modified-Since","0");

httpReq.send(null);

}

从上面可以看到httqreq没有指定编码格式。默认就是ISO-8859-1。

2.11 接收ajax处理的服务器端代码

public ModelAndView handleRequestInternal(HttpServletRequest request,

HttpServletResponse response) throws Exception {

if (request.getMethod().equals("GET")) {

String encodeProj = request.getParameter("projectname");

if (logger.isInfoEnabled()) {

logger.info("before decode:" + encodeProj);

}

//客户端经过编码后的汉字

String projectname= new String( encodeProj.getBytes( "8859_1" ) , "gb2312" );

if (logger.isInfoEnabled()) {

logger.info("after decode:" + projectname);

}2.12 JBOSS4.2配置

D:\jboss-4.2.2.GA\server\default\deploy\jboss-web.deployer \Server.xml 里面

-->

maxThreads="250" maxHttpHeaderSize="8192"

emptySessionPath="true" protocol="HTTP/1.1"

enableLookups="false" redirectPort="8443" acceptCount="100"

connectionTimeout="20000" disableUploadTimeout="true"  />

没有修改URIEncoding
