1.Struts配置：

<!-- 借款 -->

    <package name="loanAjax" namespace="/bns/loanAjax" extends="custom-rest-default">
        <action name="*/*" method="{2}" class="cn.ac.sec.match.bns.loan.action.{1}Action">
        	<result type="stream">
                <param name="contentType">text/html</param><!-- 默认为text/plain -->
                <param name="inputName">inputStream</param><!-- 默认就为inputStream -->
            </result>
        </action>
    </package>

2.脚本代码：

    function queryCusmanagerByAjax(){
    	var cusmanagerId=$('#cusmanagerId').val();
    	$.ajax({
		        type:"post",url: $("#contentPath").val()+"/bns/loanAjax/LoanCusmanager/queryByAjax.do?cusmanagerId="+cusmanagerId,dataType:"json",async: false,cache:false,success: function (data) {
		        	alert("Ajax请求数据成功!");
		         	alert(data.managerNo);
				},error: function () {
		        	alert("Ajax请求数据失败!");
		        }
			});
    }

    public void  queryByAjax(){
    	LoanCusmanager lc = loanCusmanagerManager.findByProperty("managerNo",cusmanagerId);
    	 HttpServletResponse response = this.getResponse();
    	 PrintWriter out = null;
    	 JSONObject jsonObject = JSONObject.fromObject(lc);  
    	 try {
			out = response.getWriter();
			out.print(jsonObject);
    	 } catch (IOException e) {
			e.printStackTrace();
    	 }
    }
