Struts JSP XML UP HTML

在包下建立名为pageckage.properties的文件.我这里的包是com.内容如下:

requiredstring = $\{getText(fieldName)} is required.

password = Password

username = User Name

这里我们需要改一下我们的LoginAction-validation.xml:

<message>Username is required</message>

<message>Password is required</message>

红色-号标志的为原先内容,+号内容为现在修改后的内容.

<%@ page language="java" pageEncoding="GB18030"%>

<%@taglib prefix="s" uri="/struts-tags"%>

<html>

<head>

<title>My JSP 'login' starting page</title>

</head>

<body>

<s:form action="login" method="post">

<s:textfield name="username" label="%{getText('username')}" />

<br />

<s:textfield name="password" label="%{getText('password')}" />

<br />

<s:submit />

</s:form>

</body>

</html>

struts.xml文件:

<result name="input">/login.jsp</result>

<result>/success.jsp</result>

</action>

</package>

</struts>

LoginAction文件:

package com;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport

{

private static final long serialVersionUID = 4771028725069625041L;

private String username;

private String password;

public String getUsername()

{

return username;

}

public void setUsername(String username)

{

this.username = username;

}

public String getPassword()

{

return password;

}

public void setPassword(String password)

{

this.password = password;

}

@Override

public String execute()

{

System.out.println(getText("username") + ":" + username);

System.out.println(getText("password") + ":" + password);

return SUCCESS;

}

properties文件的内容按以下顺序检索:

Resource bundles are searched in the following order:

ActionClass.properties
BaseClass.properties (all the way to Object.properties)
Interface.properties (every interface and sub-interface)
ModelDriven's model (if implements ModelDriven), for the model object repeat from 1
package.properties (of the directory where class is located and every parent directory all the way to the root directory)
search up the i18n message key hierarchy itself
global resource properties
