Ajax 具体实例

var requestCol = [];

  for(var .... ){
     var requestObj = new Object();
      requestObj.id = 1;
      requestObj,name="Jim";
      requestCol.push(requestObj);
  }
$.post("request.action", {"requestCol":JSON.stringify(requestCol)}, function (result) {
          if(result.status=="error"){
             //Error ....
          }else{
            //Success .... 
          }
      }, "json");

private Collection<RequestObj> requestCol;

//注入
public void setRequestCol(String requestCol) {
        this.requestCol = (Collection<RequestObj>) JSONArray.toCollection(JSONArray.fromObject(requestCol),
                RequestObj.class);
    }

public String saveRequestObj() throws IOException {
        HttpServletResponse response = ServletActionContext.getResponse();
        response.setContentType(HTML_CONTENT_TYPE);
        JSONObject jsonObj = new JSONObject();
        try {
         //处理requestCol对象
        } catch (SfjServiceException | SfjRuntimeTransactionException e) {
          //处理出现的异常
        } finally {
            response.getWriter().print(jsonObj.toString());
        }
        return NONE;
    }

使用JSON处理的jar包：json-lib-2.2.2-jdk15.jar
