**一 action**

package org.crazyit.app.action;
    
    import com.opensymphony.xwork2.*;
    
    
    public class LoginAction extends ActionSupport
    {
        // 下面定义了两个成员变量，用于封装请求参数
        private String username;
        private String password;
    
        // username的setter和getter方法
        public void setUsername(String username)
        {
            this.username = username;
        }
        public String getUsername()
        {
            return this.username;
        }
    
        // password的setter和getter方法
        public void setPassword(String password)
        {
            this.password = password;
        }
        public String getPassword()
        {
            return this.password;
        }
    
        // 处理用户请求的execute方法
        public String execute() throws Exception
        {
            ActionContext ctx = ActionContext.getContext();
            if (getUsername().equals("crazyit.org")
                && getPassword().equals("leegang"))
            {
                ctx.getSession().put("user" , getUsername());
                // 获取国际化消息
                ctx.put("tip" , getText("succTip"));
                return SUCCESS;
            }
            // 获取国际化消息
            ctx.put("tip" , getText("failTip"));
            return ERROR;
        }
    }

**二 校验文件**

<?xml version="1.0" encoding="GBK"?>
    <!DOCTYPE validators PUBLIC
        "-//Apache Struts//XWork Validator 1.0.3//EN"
        "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
    <validators>
        
        <field name="username">
            
            <field-validator type="requiredstring">
                <param name="trim">true</param>
                <message key="username.required"/>
            </field-validator>
        </field>
    </validators>

**三 配置文件**

<?xml version="1.0" encoding="GBK" ?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
    <struts>
        <constant name="struts.i18n.encoding" value="GBK"/>
        
        <constant name="struts.custom.i18n.resources" value="mess"/>
        
           <package name="lee" extends="struts-default">
            <action name="login" class="org.crazyit.app.action.LoginAction">
                <result name="input">/WEB-INF/content/loginForm.jsp</result>
                <result>/WEB-INF/content/result.jsp</result>
                <result name="error">/WEB-INF/content/result.jsp</result>
            </action>
            <action name="*">
                <result>/WEB-INF/content/{1}.jsp</result>
            </action>
        </package>
    </struts>

**四 资源文件**

# 在JSP页面使用的JSP范围的资源文件
    loginPage=Global Message:Login Page
    user=Global Message:User Name
    pass=Global Message:User Pass
    login=Global Message:Login
    resultPage=Log In Result
    # 在Action中使用的国际化消息
    failTip=Global Scope:Sorry,You can't log in!
    succTip=Global Scope:welcome,you has logged in!
    # 在Action校验规则文件中使用的国际化消息
    username.required=Global Scope: User Name is required!

**五 视图**
