java-web交流群：132607763
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;}}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;}}<%@ page language="java" contentType="text/html" pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %><%@ taglib uri="/struts-dojo-tags" prefix="sd" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>${title}aa</title><sd:head parseContent="true"/></head><body><s:form action="addBook"><s:label value=" 添加图书"></s:label><s:textfield name="book.name" label="书名："></s:textfield><s:textfield name="book.author" label="作者"></s:textfield><sd:datetimepicker name="book.publishDate" label="出版时间"></sd:datetimepicker><s:submit value="提交"></s:submit></s:form></body></html>
