Struts2接受请求参数2（集合类数据）

效果类似输入多组数据：





输出结果：[User [username=admin, password=123456], User [username=root, password=654321]]

Html代码块：

<form action="loginAction" method="post">
用户名：<input type="text" name="user[0].username"><br>
密 码：<input type="password" name="user[0].password"><br>
<hr>
用户名：<input type="text" name="user[1].username"><br>
密 码：<input type="password" name="user[1].password"><br>
<input type="submit" value="Submit">
</form>

action代码块：
public class LoginAction{
private List<User> user;
public List<User> getUser() {
return user;
}
public void setUser(List<User> user) {
this.user = user;
}

public String execute(){
System.out.println(user);
return "success";
}
}


User实体类：
public class User {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public User(String username, String password) {
super();
this.username = username;
this.password = password;
}

@Override
public String toString() {
return "User [username=" + username + ", password=" + password
+ "]";
}
public User() {
super();
}
}
