从页面接收json格式的数据，在java类里面进行解析
String jsonStr = {"name":"zfj","dd":[{"ddr":"1","encrypt":"2","ff":"1","length":"23","ffe":"editStyled","ill":"1","pkor":"2","name":"zfj","isKey":"2","alias":"ffff"}],"addRelations":[{"type":"2","ld":"zfj","ld":"2"}]};
将此字符串放在ruquest或者其他的变量里面，传递到后台。
如放在reques中：
("/geServlet?data="+jsonStr).forward(request,response);
在servlet或java类里这样接收：
String json = [size=large][/size]tParameter("data");
JSONObject jsonObject = (data);
String name = （“name”）；
......
//对于数组这样接收用
JSONArray jan = (JSONArray) ("dd");
if(jan!=null||()!=0){
for(int i=0;i<();i++){
JSONObject jo = ((i));
String ff = ("ff");
......
}
}
因为我包中没有fromObject、toList，所以用了下面的方法：
import ;
.
.
.
ArrayList<SystemMessageInfo> sysMessageInfoList = (resObj,
new TypeReference<ArrayList<SystemMessageInfo>>() {
});
完整的：
1.
import ;
public String GetMultiLangMessage(String key, String defaultString) {
try {
if (() == null) {
sysMsgMap=new HashMap<Integer, SystemMessageInfo>();
LinkedHashMap<String, Object> params = new LinkedHashMap<String, Object>();
("clientName", ());
String resObj = (
"GetSystemMessageForList", params);
("GetMultiLangMessage resObj", resObj);
if (!(resObj)) {
("msg");
}
if((resObj)){
return defaultString;
}
else
{
ArrayList<SystemMessageInfo> sysMessageInfoList = (resObj,
new TypeReference<ArrayList<SystemMessageInfo>>() {
});
for (SystemMessageInfo systemMessageInfo : sysMessageInfoList) {
((), systemMessageInfo);
}
}
}
String strValString = "";
sysMsgInfo = ((key));
if (sysMsgInfo!=null) {
strValString = (sysMsgInfo.getSysMegName1(),
sysMsgInfo.getSysMegName2(),
sysMsgInfo.getSysMegName3(),
sysMsgInfo.getSysMegName4(),
sysMsgInfo.getSysMegName5());
}
if ((strValString)) {
strValString = defaultString;
}
return strValString;
} catch (Exception e) {
if(e instanceof NetworkErrorException){
().getCurrentScreen().ShowMessageBox(
"", (), , new Object[]{});
}
else {
().getCurrentScreen().ShowMessageBox(
"","Application error, please get assistance from IT administrator!", e, );
}
return defaultString;
}
