struts2 Action获取表单传值（属性，类)）

1.通过属性驱动式

JSP:

<form action="sys/login.action" method="post">

<input type="text" name="username">

<input type="submit" value="submit">

</form>

Action:直接通过get、set方法获取。

[java]
view plaincopyprint?

public class sysAction extends ActionSupport{
private String username;

public String login() throws Exception {
System.out.println(username);
return SUCCESS;
}

public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username= username;
}
}

2.第二种方式类获取
JSP:

<form action="sys/login.action" method="post">

<input type="text" name="user.username">

<input type="text" name="teacher.level">

<input type="submit" value="submit">

</form>

Action: 必须提供set方法

[java]
view plaincopyprint?

public class sysAction extends ActionSupport{
private User user;
private Teacher teacher;

public String login() throws Exception {
System.out.println(user.getUsername());
System.out.println(teacher.getLevel());
return SUCCESS;
}

public void setUser(User user) {
this.user = user;
}
public void setTeacher(Teacher teacher) {
this.teacher = teacher;
}
}
