4种方法,详情见:http://blog.csdn.net/lutinghuan/article/details/46820023
第一种:
1.新增类,其中有属性为该对象的集合
public class SettingModel {
private List<Setting> sets; public final List<Setting> getSets() {
return sets;
} public final void setSets(List<Setting> sets) {
this.sets = sets;
} @Override
public String toString() {
return "SettingModel [sets=" + sets + "]";
} }
2.表单字段name属性值为数组形式:
<form action="/user/submitUserList_2" method="post">
ID:<input type="text" name="users[0].id"><br/>
Username:<input type="text" name="users[0].name"><br/>
Password:<input type="text" name="users[0].pwd"><br/><br/> ID:<input type="text" name="users[2].id"><br/>
Username:<input type="text" name="users[2].name"><br/>
Password:<input type="text" name="users[2].pwd"><br/><br/>
<input type="submit" value="Submit">
</form>
3.后台接收:
@RequestMapping("/update")
public void update(SettingModel users){
System.out.println(sets);
}
第二种:
1.ajax请求,POST请求、'Content-Type' : 'application/json;charset=utf-8'、data:json(例如:[{"id":"1","content":"14"},{"id":"2","content":"测试修改2"}])
$.ajax({
url:'/update',
type:'POST',
headers : {
'Content-Type' : 'application/json;charset=utf-8'
},
dataType:"json",
data:datastr,//datastr=JSON.stringify(datastr);转换为JSON格式
success: function(data){
alert('111');
}
});
2.后台接收:
@RequestMapping(value="/update")
public void update(@RequestBody List<Setting> sets){
System.out.println(sets);
}
