Action中有对象属性，表单提交后，action自动为对象赋值。
book类：

package com.mm.entity;

import java.util.Date;

public class Book {

	private String name;
	private String author;
	private Date publishDate;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getAuthor() {
		return author;
	}

	public void setAuthor(String author) {
		this.author = author;
	}

	public Date getPublishDate() {
		return publishDate;
	}

	public void setPublishDate(Date publishDate) {
		this.publishDate = publishDate;
	}

	public String toString() {
		return this.name + ":" + this.author + ":" + this.publishDate;
	}

}

action类

package com.mm.action;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;

import com.opensymphony.xwork2.ActionSupport;
import com.mm.entity.Book;

@ParentPackage("struts2Test")
public class BookAction extends ActionSupport {

	private static final long serialVersionUID = 1L;

	private String title;
	private Book book;

	@Action(value = "addBook", results = { @Result(name = SUCCESS, location = "/book.jsp") })
	public String add() {
		System.out.println(book);
		title = "添加成功";
		return SUCCESS;
	}

	@Action(value = "clear", results = { @Result(name = SUCCESS, location = "/book.jsp") })
	public String clear() {
		title = "清空了";
		return SUCCESS;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public Book getBook() {
		return book;
	}

	public void setBook(Book book) {
		this.book = book;
	}

}
