struts2 入门

先把 struts2里的lib包中commons-logging.jar  freemarker.jar   ognl.jar  struts2-core.jar  、xwork.jar拷到web-inf/lib里。废话少说：

首先编写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" 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">
<filter>
 <filter-name>struts2</filter-name>
 <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

编写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>
        <package name="ActionDemo" extends="struts-default">
        <action name="Login" class="skycliff.Login">
        <result name="success">/login.jsp</result>
        <result name="false">/login.jsp</result>
        </action>
        </package>
       </struts>

 

action的代码 Login .java

package skycliff;

import com.opensymphony.xwork2.ActionSupport;

public class Login  {
private String name;
private String password;
public String message;
public String getName() {
 return name;
}
public void setName(String name) {
 this.name = name;
}
public String getPassword() {
 return password;
}
public void setPassword(String password) {
 this.password = password;
}
public String execute(){
 if(name.equals("skycliff")&&password.equalsIgnoreCase("syit"))
 {message=name+"，您应经登陆成功！";
 return "success";}
 
 else{
  message="登录失败";
  return "false";
 }
 
}
}

 

测试用例的代码LoginTest.java

package skycliff;

import junit.framework.TestCase;

public class LoginTest extends TestCase {

 public void testExecute() {
  Login login=new Login();
  login.setName("skycliff");
  login.setPassword("syit");
  assertTrue("deteceted the result","success".equalsIgnoreCase(login.execute()));
  login.setPassword("sdfasdf");
  assertTrue("deteceted the result","false".equalsIgnoreCase(login.execute()));
 }

}

好了，享受struts2带给我们的快乐吧！
