手工创建Struts项目的简单例子

来源：互联网发布：鹏为软件e5 编辑：程序博客网时间：2024/05/03 04:43

1、在Tomcat中建立一个空站点

2、将必须的包放入WEB-INF/lib下，有
jstl.jar
standard.jar
commons-beanutils-1.8.0.jar
commons-chain-1.2.jar
commons-digester-1.8.jar
struts-core-1.3.10.jar

3、修改web.xml文件，如：
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
        xmlns="http://java.sun.com/xml/ns/j2ee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
        <display-name>webapp</display-name>
        <welcome-file-list>
                <welcome-file>index.html</welcome-file>
                <welcome-file>index.htm</welcome-file>
                <welcome-file>index.jsp</welcome-file>
                <welcome-file>default.html</welcome-file>
                <welcome-file>default.htm</welcome-file>
                <welcome-file>default.jsp</welcome-file>
        </welcome-file-list>
        <servlet>
                <servlet-name>action</servlet-name>
                <servlet-class>
                        org.apache.struts.action.ActionServlet
                </servlet-class>
                <init-param>
                        <param-name>config</param-name>
                        <param-value>/WEB-INF/struts-config.xml</param-value>
                </init-param>
        </servlet>
        <servlet-mapping>
                <servlet-name>action</servlet-name>
                <url-pattern>*.do</url-pattern>
        </servlet-mapping>
</web-app>

4、新建登录网页index.jsp，内容为：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!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>Insert title here</title>
</head>
<body>
<form action="login.do" method="POST">
<input type="text" name="loginName">
<input type="password" name="loginPass">
<input type="submit" value="submit" >
</body>
</html>

5、创建LoginForm.java，内容为：
package app;

import org.apache.struts.action.ActionForm;

public class LoginForm extends ActionForm {
String loginName;

String loginPass;

public LoginForm() {

}

        public LoginForm(String user, String pass) {
                setLoginName(user);
                setLoginPass(pass);
        }

        public String getLoginName() {
                return loginName;
        }

        public void setLoginName(String loginName) {
                this.loginName = loginName;
        }

        public String getLoginPass() {
                return loginPass;
        }

        public void setLoginPass(String loginPass) {
                this.loginPass = loginPass;
        }
}

编译方法为（将struts-core-1.3.10.jar文件放入当前目录）：
javac -d . -classpath .;struts-core-1.3.10.jar LoginForm.java

将编译后的包类放入WEB-INF/classes

6、创建LoginAction.java，内容为：
package app;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class LoginAction extends Action {
        public ActionForward execute(ActionMapping mapping, ActionForm form,
                        HttpServletRequest arg2, HttpServletResponse arg3) throws Exception {
                LoginForm lf = (LoginForm) form;
                if (lf.getLoginName().trim().equals(lf.getLoginPass().trim()))
                        return mapping.findForward("success");
                else
                        return mapping.findForward("failure");

}
}

编译方法为（将struts-core-1.3.10.jar和servlet-api.jar文件放入当前目录）：
javac -d . -classpath .;struts-core-1.3.10.jar;servlet-api.jar LoginAction.java

将编译后的包类放入WEB-INF/classes

7、新建struts-config.xml，放入WEB-INF目录下，内容为：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config SYSTEM "http://struts.apache.org/dtds/struts-config_1_3.dtd" >
<struts-config>
        <form-beans>
                <form-bean name="loginForm" type="app.LoginForm" />
        </form-beans>

        <action-mappings>
                <action path="/login" type="app.LoginAction"
                        name="loginForm" validate="false" scope="request">
                        <forward name="success" path="/success.html" />
                        <forward name="failure" path="/failure.html" />
                </action>
        </action-mappings>
</struts-config>

8、创建success.html文件，内容为：
<HTML>
<HEAD>
   <TITLE>SUCCESS</TITLE>
</HEAD>
<BODY>
   Registration succeeded!
   <P><A href="index.jsp">try another?</A></P>
</BODY>
</HTML>

9、创建failure.html文件，内容为：
<HTML>
<HEAD>
   <TITLE>FAILURE</TITLE>
</HEAD>
<BODY>
   Registration failed!
   <P><A href="index.jsp">try again?</A></P>
</BODY>
</HTML>

10、即可运行，因为Tomcat自动缓存，所以每次修改后要及时将<Tomcat>/work目录下的内容清空
