struts2中的action：

public void getSynonymy()
{
DataJsonBean dataBean = new DataJsonBean();
dataBean.setInterestNameString("['低','中','高']");
dataBean.setInterestValueString("['3','1','8']");

String resultStr = this.getChinese();

resultStr = new String(resultStr.getBytes("iso-8859-1"),"UTF-8");

dataBean.setChinese(resultStr+"的同义近义词");
JSONObject data = new JSONObject(dataBean);

PrintWriter out = null;
try
{
HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("application/json;charset=UTF-8");
out = response.getWriter();
out.print(data.toString());
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
finally
{
out.flush();
out.close();
}
}

展示的jsp:

//引用struts2的标签

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

//获取工程的路径：

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<script type="text/javascript">

function search(method)
{
$.getJSON("<%=basePath%>semanticRelationshipAction!"+method+".action",{chinese:$("#chinese").val()},
function(data)
{

$("#result").css({display:"block"});
$("#labelChinese").html(data.chinese);
alert(data.interestNameString);
aturCommonLoad(data.interestNameString,data.interestValueString);
}
);
}
</script>

<input class="ttinput" type="text" name="chinese" id="chinese"/>

<input class="ttbutton" type="button" value="同义近义" onclick="search('getSynonymy')"/>

<div id="result" class="result" style="display: none">
<div class="texttitile" id="labelChinese"></div>
<div id="interest"></div>
</div>
