从前台传数组进入后台使用ajax
前台代码:
如果Post是string数组或者int数组,则ajax中traditional: true,
如果Post是对象数组,则ajax中traditional: false,否则对象将为空
/ajax中 需要设置 traditional:true,
$.ajax({url:"http://localhost:8085/computer/answer",
dataType:'json',
type:"post",
traditional:true,
data:{
answer:answer,
questionid:questionIds,
tid:this.test[0].tid
},
success:function(data){
}
后台代码
@RequestMapping(value="answer")
public List dealAnswer(String [] answer,Integer [] questionid,Integer tid){
System.out.println(answer.length);
System.out.println(questionid.length);
System.out.println(tid);
return null;
}
