一、以modelandview的方式返回
先看下javascript代码：
/**
* 保存-同步(版本控制库)
*/
function savesynchronizedvchorse(obj) {
var ss = $("#synchronizedselection div");
var cacheselectary = new array()
for(var i = 0; i < ss.length; i ++) {
//alert(ss.eq(i).html());
//alert(ss.eq(i).find('label').html());
var o=ss.eq(i).find('label').find("input[type='checkbox']");
var s = $(o).attr('checked');//由于$(obj).attr("checked", false); checked属性会被
if(s != null) {
cacheselectary.push($(o).attr('value'));
}
}
if(cacheselectary.length == 0) {
alert("请选择城市");
return;
}
var json = "synchronizedbean={\"exceptionid\":\""+exceptionid+"\",\"cityids\":["
for(var i = 0; i < cacheselectary.length; i ++) {
if(i == cacheselectary.length -1) {
json = json +"\""+ cacheselectary[i] + "\"";
} else {
json = json + "\"" + cacheselectary[i] + "\",";
}
}
json = json + "]}";
$.ajax({
type: "post",
datatype: "json",
url: "../main/savesynchronizeddata",
data: json,
success: function(msg){
alert(msg.main);
},
error: function () {//xmlhttprequest, textstatus, errorthrown
alert("请求失败");
}
});
}
主要是看ajax请求部分。
再看spring 中控制器的代码：
@requestmapping(value = "/savesynchronizeddata", method = requestmethod.post)
public @responsebody modelandview savesynchronizeddata(@requestparam("synchronizedbean") string msynchronizedjson) {
objectmapper objectmapper = new objectmapper();
map map = new hashmap();
try {
synchronizedbean bean = objectmapper.readvalue(msynchronizedjson, synchronizedbean.class);
if(bean != null) {
string[] ary = bean.getcityids();
if(ary != null && ary.length > 0) {
for(string s : ary) {
vchousepo po = new vchousepo();
po.setexceptionid(bean.getexceptionid());
po.setcustomercode(s);
po.setcreatetime(new date());
po.setexceptionstate(0);
vchservice.add(po);
}
}
}
map.put("msg", "success");
} catch (jsonparseexception e) {
e.printstacktrace();
map.put("msg", "error");
} catch (jsonmappingexception e) {
e.printstacktrace();
map.put("msg", "error");
} catch (ioexception e) {
e.printstacktrace();
map.put("msg", "error");
}
return new modelandview(new mappingjackson2jsonview(),map);
}
这里是通过modelandview的方式进行返回json的。另外：mappingjackson2jsonview使用的package是
import org.springframework.web.servlet.view.json.mappingjackson2jsonview;
