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();
	}
}
