json格式转换成Map的应用

jsp

1.引用json.js（将json格式转换成字符串）

2.

var name = document.getElementById("name").value;
  var retries = document.getElementById("retries").value;
  var testname = document.getElementById("testname").value;
  var testretries = document.getElementById("testretries").value;
  //定义一个JSON对象
  var paramObject= {"name":name,"retries":retries,"testname":testname,"testretries":testretries};
  //将json对象转换成字符串传递到后台
  var paramMap=JSON.stringify(paramObject);

3.

java中直接遍历成Map：

/**
    * 将json格式的字符串解析成Map对象 <li>
    * json格式：{"name":"admin","retries":"3fff","testname"
    * :"ddd","testretries":"fffffffff"}
    */
   private static HashMap<String, String> toHashMap(Object object)
   {
       HashMap<String, String> data = new HashMap<String, String>();
       // 将json字符串转换成jsonObject
       JSONObject jsonObject = JSONObject.fromObject(object);
       Iterator it = jsonObject.keys();
       // 遍历jsonObject数据，添加到Map对象
       while (it.hasNext())
       {
           String key = String.valueOf(it.next());
           String value = (String) jsonObject.get(key);
           data.put(key, value);
       }
       return data;
   }

或者转换成字符串对象：

获取国际化key和value

 

/**
   * 将json格式的字符串解析成String字符串平装<li>
   * json格式：String objString = "{\"aa\":1,\"cc\":2,\"bb\":3}";
   */
  @SuppressWarnings( {"unchecked"})
  private String toAnnotationStr(Object object)
  {
      // HashMap<String, String> data = new HashMap<String, String>();
      // 将json字符串转换成jsonObject
      if (object != null && !object.equals(""))
      {
          JSONObject jsonObject = JSONObject.fromObject(object);
          Iterator it = jsonObject.keys();
          StringBuilder strBuilder = new StringBuilder();
          // 遍历jsonObject数据，添加到Map对象
          while (it.hasNext())
          {
              String key = String.valueOf(it.next());
              String value = (String) jsonObject.get(key);
              //TODO
              strBuilder.append(this.getText(key))
                      .append(this.getText("lego.lab.com.colon"))
                      .append(value + " ");

          }
          return strBuilder.toString();
      }
      else
      {
          return "";
      }
  }
