Struts2基础框架搭建
【功能概述】
1. 搭建Struts2应用框架, 实现由UI层向控制器的数据传递;
2. 手工加载Struts2的jar包;
【配置说明】
IDE: MyEclipse 6.0
DB: Oracle 10g
Struts version: Struts 2.1.6
Struts Library: < struts2-core-2.1.6.jar
xwork-2.1.2.jar
ognl-2.6.11.jar
freemarker-2.3.13.jar
commons-logging-api-1.1.jar
commons-fileupload-1.2.1.jar >
【源代码】
1. UI层：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><html><head><title>Add Employee</title></head><body><!-- 注意: .action后缀不写亦可 --><form action="EmployeeAction.action" method="post"><input type="text" name="empno"><br><input type="text" name="ename"><br><input type="text" name="hiredate"><br><input type="submit" value="submit"></form></body></html>
2. web.xml
<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><!-- Struts2 Configuration --><filter><filter-name>FilterDispatcher</filter-name><filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class></filter><filter-mapping><filter-name>FilterDispatcher</filter-name><url-pattern>/*</url-pattern></filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>
3. Struts2核心配置文件: struts.xml
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN""http://struts.apache.org/dtds/struts-2.0.dtd"><struts><!-- 注意: name属性是必须的, 值可以任意 --><!-- extends属性非必须, 但如果不写的话, 无法将UI层的输入值注入到控制器属性中. --><package name="default" extends="struts-default"><!-- result的配置不是必须的(此处没有配置result) --><action name="EmployeeAction" name="code">package com.howin.action;import com.opensymphony.xwork2.Action;//★注意: Struts2控制器可以不实现任何接口//也可实现Action接口//或者继承ActionSupport(输入校验使用)public class EmployeeAction{//★注意: 属性名必须与UI层页面输入标签的name保持一致private String empno;private String ename;private String hiredate;//注意:属性的setter方法是必须的, 否则无法将UI层输入的值注入到属性中public void setEmpno(String empno){this.empno = empno;}public void setEname(String ename){this.ename = ename;}public void setHiredate(String hiredate){this.hiredate = hiredate;}public String execute(){System.out.println(empno+ename+hiredate);return null;}}
