新建一个工程struts2工程teaweb(因为现在所做的项目是一个关于茶叶，茶文化的)，导入jar包(基本的几个jar包：commons-logging-1.0.4.jar，freemarker- 2.3.8.jar，ognl-2.6.11.jar，struts2-core-2.0.10.jar，xwork-2.0.4.jar)，配置 struts.xml配置内容如下
注意此处的：extends="json-default" ，
配置web.xml,内容如下：
struts2
org.apache.struts2.dispatcher.FilterDispatcher
struts2
*.ph
struts2
*.jsp
/WEB-INF/struts-tags.tld
/WEB-INF/struts-tags.tld
index.jsp
新建一个java类为TestAction，java代码为：
package com.teaweb.action;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.List;
import com.teaweb.bean.TestBean;
import com.teaweb.dao.TestDAO;
public class TestAction extends PublicAction {
private TestBean testBean;
private long results;
private TestDAO testDAO=new TestDAO();
private List list;
public String select() {
// TODO Auto-generated method stub
response.setCharacterEncoding("gb2312");
list=testDAO.select();
results=list.size();
return SUCCESS;
}
public String login() {
// TODO Auto-generated method stub
try {
request.setCharacterEncoding("utf-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
response.setCharacterEncoding("gb2312");
TestBean result=testDAO.selectbyname(testBean);
if(result!=null){
outString("{success:true,msg:'"+result.getName()+"登录成功'}");
}else{
outString("{failure:true,msg:'登录失败'}");
}
return null;
}
public TestBean getTestBean() {
return testBean;
}
public void setTestBean(TestBean testBean) {
this.testBean = testBean;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
public long getResults() {
return results;
}
public void setResults(long results) {
this.results = results;
}
}
其中TestBean 是一个实体类，还有一个连接数据库查询的方法，只要能查出为List结果就可以了
我这里做了一个登陆和查询所有TEST表里的信息两个方法
其中login.jsp代码为：
My JSP 'login.jsp' starting page
Ext.onReady(function(){
Ext.QuickTips.init();
var form1=new Ext.FormPanel({
renderTo:"panel1",
width:500,
height:300,
frame:true,
title:"ajax提交",
collapsible:true,
minButtonWidth:60,
labelAlign:"right",
defaultType:"textfield",
url:"test!login.ph",
items:[{
fieldLabel:"用户名",
id:"txtName",
name:'testBean.name',
allowBlank:false,
blankText:"用户名不能为空!"
},{
fieldLabel:"密码",
allowBlank:false,
blankText:"密码不能为空!",
name:'testBean.password',
inputType:'password'
},{
fieldLabel:"备注"
}],
buttons:[{
text:"提交",
handler:function(){
if(form1.getForm().isValid()) {
form1.getForm().submit({
success:function(from,action) {
Ext.Msg.alert("返回提示",action.result.msg);
window.location = 'index.jsp';
},
failure:function(form,action) {
Ext.Msg.alert("返回提示",action.result.msg);
}
});
}
}
},{
text:"重置",
handler:function() {
form1.getForm().reset();
}
}]
});
});
其中index.jsp页面代码为：
index
Ext.onReady(function(){
var store=new Ext.data.JsonStore({
url:"test!select.ph",
totalProperty: "results",
root: "list",
fields:[{name:'id',mapping:'id'}, {name:'name',mapping:'name'},{name:'password',mapping:'password'}]
});
store.load();
var gird=new Ext.grid.GridPanel({
renderTo:"hello",
title:"欢迎登录",
height:150,
width:300,
columns:[
{header:"编号",dateindex:"id"},
{header:"账号",dateindex:"name"},
{header:"密码",dateindex:"password"}
],
store:store,
autoExpandColumn:2
})
})
