菜鸟学struts2，高手指点下，老是报错：The requested resource is not available
1、login.jsp
<form action="login.action" method="post">
userName:<input type="text" name="username"><br>
passWord:<input type="text" name="password"><br>
<input type="submit" value="submit">
</form>
2、result.jsp
<body>
userName:${requestScope.username }<br>
password:${requestScope.password }
</body>
3、类LoginAction
package com.test.action;
public class LoginAction {
private String username;
public String getUserName() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
private String password;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String execute() throws Exception
{
return "success";
}
}
4、struts配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="struts2" extends="struts-default">
<action name="login" class="com.test.action.LoginAction">
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
5、过滤
<?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">
<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>
</web-app>
[解决办法]
userName:${requestScope.username }<br>
password:${requestScope.password }
改为
userName:${username }<br>
password:${password }
[解决办法]
getUserName 是不是应该改为 getUsername比较好？
[解决办法]
2楼说对了，，定义的get方法不能随心所欲。。
如果是getUserName 程序会去找userName 这个属性，没有就报错了
