struts2 结合extjs实现的一个登录实例

二、再导入extjs所需的库文件。

三、写一个实体类User

package com.ext.model;

public class User {
private Integer id;
private String username;
private String password;
public Integer getId() {
    return id;
}
public void setId(Integer id) {
    this.id = id;
}
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;
}
}

四、写LoginAction

package com.ext.action;

import com.ext.model.User;
import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport    {
private boolean success;
private String message;
private User user;

@Override
    public String execute() throws Exception {
        // TODO Auto-generated method stub
        if(user.getUsername().equals("admin")&&user.getPassword().equals("admin")){
            this.success= true;
            //this.message="你的账号是："+user.getUsername()+"密码是："+user.getPassword();
        }else{
            this.success=false;
            this.message="对不起，未授权的用户不能登录改系统";
        }
        return SUCCESS;
    }

public boolean isSuccess() {
    return success;
}

public void setSuccess(boolean success) {
    this.success = success;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

public User getUser() {
    return user;
}

public void setUser(User user) {
    this.user = user;
}

}

五、struts.xml如下所示：

六、login.jsp

七、login.js

Ext.onReady(function(){
Ext.QuickTips.init();
Ext.form.Field.prototype.msgTarget="side";

var form1=new Ext.FormPanel({
    labelWidth:40,
    baseCls:‘x-plain‘,
    defaults:{width:180},
    items:[{
        xtype:‘textfield‘,
        fieldLabel:"用户名",
        id:"txtName",
        name:‘user.username‘,
        allowBlank:false,
        blankText:"用户名不能为空!"
        },{
        xtype:‘textfield‘,
        fieldLabel:"密码",
        allowBlank:false,
        blankText:"密码不能为空!",
        name:‘user.password‘,
        inputType:‘password‘
        }],
    buttons:[{
        text:"提交",
        type:‘submit‘,
        handler:function(){
            if(form1.getForm().isValid()) {
            Ext.MessageBox.show({
                title:‘请等待‘,
                msg:‘正在加载‘,
                progressText:‘‘,
                width:300,
                progress:true,
                closable:‘false‘,
                animEl:‘loding‘
            });    
            var f = function(v){
                return function(){
                    var i=v/11;
                    Ext.MessageBox.updateProgress(i,‘‘);
                }
            }
            for(var i=1;i

八、登录成功的index页面就不写了。
用extjs实现页面间的跳转开始学有点麻烦，注意红色部分。
