前端页面表单提交多个name相同的input框，后台接收方法

一、以字段数组接收

<form action="/user/submitUserList_1" method="post">
        ID:<input type="text" name="id"><br/>
        Username:<input type="text" name="name"><br/>
        Password:<input type="text" name="pwd"><br/><br/>

        ID:<input type="text" name="id"><br/>
        Username:<input type="text" name="name"><br/>
        Password:<input type="text" name="pwd"><br/><br/>
        <input type="submit" value="submit">
    </form>

①

private List<String> id = new ArrayList<String>();
private List<String> name = new ArrayList<String>();
private List<String> pwd = new ArrayList<String>();
//对应的getter 和setter

//或者

private String[] id;
private List<String> name;
private List<String> pwd;

②

String[] ids = request.getParameters("id");
String[] names = request.getParameters("name");
String[] pwds = request.getParameters("pwd");

注意：参数名称需与页面中name的值一致，获得的参数为数组，在方法中遍历即可

二、以List集合Model接收

<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>

Java代码：

public class User{

    private Integer id;
    private String name; 
    private String pwd; 

    //对应 getter setter
}

private List<Users> users;
//对应 getter setter
