Action實現方式:

1.  普通java類

2.  實現action介面實現execute方法

3.  繼承ActionSupport類

取值方式：

1.  成員屬性set方法取值

2.成員實體屬性

Page：

<form action="loginthree">

 username:<input type="text" name="person.name"value=""/>

 userpass:<input type="password" name="person.pass"value=""/>

<input type="submit"  value

</form>

Action：

publicclass LoginActionThree extends ActionSupport {

private Person person;

@Override

public String execute() throws Exception {

System.out.println("LoginActionThree.execute");

System.out.println(person.getName()+":"+person.getPass());

return"successs";

}

public String checkuser(){

System.out.println("LoginActionThree");

System.out.println(person.getName()+":"+person.getPass());

return"successs";

}

public Person getPerson() {

returnperson;

}

publicvoid setPerson(Person person) {

this.person = person;

}

}

Person.java

publicclass Person {

private String name;

private String pass

public String getName() {

returnname;

}

publicvoid setName(String name) {

this.name = name;

}

public String getPass() {

returnpass;

}

publicvoid setPass(String pass) {

this.pass = pass;

}

}
