json格式转换成Map的应用

1.引用json.js（将json格式转换成字符串）

Javascript代码

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);  

2.java中直接遍历成Map：

Java代码

/**     * 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;     }  

3. 或者转换成字符串对象：

获取国际化key和value

Java代码

/**    * 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 "";        }    }
