Struts2温习(1)--最基本的示例

StrutsJSPjsonHTMLXML 
阅读更多

有关Struts1的知识大部分都已经温习完毕，今天开始转向Struts2的温习工作了

 首先解压struts-2.1.8.1的ZIP包，复制struts-2.1.8.1\apps\struts2-blank-2.1.8.1.war中lib下的jar包到项目中去，那么这几个包就是必须包



 复制struts-2.1.8.1\src\core\src\test\resources\struts.xml到项目的src下，然后进行细致的修改


具体示例【还是经典的登录示例】

login.jsp


<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
  <head>
    <title>登录示例</title>
  </head>
  
  <body>
   <form action="login.action" method="post">
   <table>
   <tr><td>用户名:</td><td><input type="text" name="loginname"/></td></tr>
    <tr><td>密码:</td><td><input type="password" name="pwd"/></td></tr>
     <tr><td colspan="2"><input type="submit" value="登录" /></td></tr>
   </table>
   </form>
  </body>
</html>

 success.jsp


<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
  <head>
    <title>主页面</title>
  </head>
  <body>
   登录成功,欢迎${param.loginname}
  </body>
</html>

LoginAction.java


package com.javacrazyer.action;


public class LoginAction {
	private String loginname;
	private String pwd;

	public String getLoginname() {
		return loginname;
	}

	public void setLoginname(String loginname) {
		this.loginname = loginname;
	}

	public String getPwd() {
		return pwd;
	}

	public void setPwd(String pwd) {
		this.pwd = pwd;
	}

	public String execute() throws Exception {
		if (loginname.equals("test") && pwd.equals("test")) {
			return "success";
		} else {
			return "index";
		}
	}

}


 


 src/struts.xml


<!DOCTYPE struts PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
          "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
  <!-- package的属性
	   name:  指定包名。要唯一。方便于其它包的继承。
	   extends: 指定要继承的包名。一般是struts-default
	   namespace: 指定命名空间。不指定时，使用默认命名空间，默认命名空间为""
	   abstract: 指定是否为抽象包。抽象包中不能有Action的配置。
	 -->
    <package name="mystruts"  extends="struts-default">
	
		<!-- action标签用来注册一个Action.常用属性 
		  name: action的名字，用于匹配请求URI。必须的。不能出现"/"
		  class: 指定Action处理类的全限定名。未指定时，默认是ActionSupport。而ActionSupport的execute() 方法默认处理就是返回一个success字符串。
		  method: 指定要调用的处理方法.不指定时，默认调用execute方法
		  converter: 指定本Action类要使用到的转换器的全限定名
		-->
        <action name="login" class="com.javacrazyer.action.LoginAction">
            <result name="success">/success.jsp</result>
            <result name="index">/index.jsp</result>
        </action>
    </package>
   
</struts>

 

总结，本示例中的Action没有继承任何第三方与Struts2有关的类，但在struts2中只要求其提供一个execute方法，并且返回个字符串的值即可。

 

对于比较复杂的实际项目来说，可能struts.xml中需要写非常多的类似代码，那么为了方便管理，可以将相关的写在别的xml文件中，然后再引入到struts.xml中来，效果也是一样

比如，在src/META-INF/struts2文件下有这么几个xml:struts2-login.xml、struts2-deliver.xml、struts2-order.xml、

struts2-member.xml、struts2-system.xml等,这几个xml分别对应为

struts2-login.xml

	</package>
	
</struts>

 

那么针对这么几个xml，在src/struts.xml中就应该像下面这么引用

<?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">

	<constant name="struts.configuration.xml.reload" value="true" />
	<constant name="struts.action.extension" value="action"></constant>
	<constant name="struts.i18n.encoding" value="UTF-8"></constant>  
	<constant name="struts.ognl.allowStaticMethodAccess" value="true" /> 
	

        <!-- 引入struts2其他类似配置文件 -->
	<include file="META-INF/struts2/struts2-login.xml" />

	<package name="default" namespace="/" extends="struts-default, json-default">
		<!-- 定义拦截器 -->

	</package>

	<!-- Add packages here -->
