ExtJS04：解决URL传递中文乱码问题

前台JS代码：

var paraName = Ext.getCmp("Unim_AssTarPar_TXT_paraName").getValue();

if (paraName != null && paraName != 'undefined' && paraName!=g_paraName_ACSF) {

var url_link = __ctxPath + '/unim/isRepeatUnimAssTarPar.do?paraName='+encodeURIComponent(paraName);

url_link = encodeURI(url_link);

var responsea = Ext.lib.Ajax.getConnectionObject().conn;

responsea.open("POST",  url_link, false);

responsea.send(null);

var result = Ext.util.JSON.decode(responsea.responseText);//解析数据

if(result.success==true) {

Ext.Msg.alert("信息提示","该参数名重复，请修改！");

Ext.getCmp("Unim_AssTarPar_TXT_paraName").focus();

return;

}

}

后台Java代码：

public String isRepeat() {

String paraName = getRequest().getParameter("paraName");

try {

if(StringUtils.isNotBlank(paraName)) {

paraName = URLDecoder.decode(paraName,"utf-8");

}

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

QueryFilter filter = new QueryFilter(getRequest());

filter.addFilter("Q_paraName_S_EQ", paraName);

List<UnimAssTarPar> list = unimAssTarParService.getAll(filter);

if(list.size()>0) {

setJsonString("{success:true}");

} else {

setJsonString("{success:false}");

}

return SUCCESS;

}
