json格式转换成Map的应用
jsp1.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 ""; } }
