EasyUI框架 使用Ajax提交注册信息的实现代码
一、服务器代码：
@Controller
@Scope("prototype")
public class StudentAction extends BaseAction<Student> {
private static final long serialVersionUID = -2612140283476148779L;
private Logger logger = Logger.getLogger(StudentAction.class);
private String rows;// 每页显示的记录数
private String page;// 当前第几页
private Map<String, Object> josnMap = new HashMap<>();
// 查询出所有学生信息
public String list() throws Exception {
return "list";
}
public String regUI() throws Exception {
return "regUI";
}
// 查询出所有学生信息
public String listContent() throws Exception {
List<Student> list = studentService.getStudentList(page, rows);
System.out.println("list==" + list);
toBeJson(list, studentService.getStudentTotal());
return "toJson";
}
// 转化为Json格式
public void toBeJson(List<Student> list, int total) throws Exception {
josnMap.put("total", total);
josnMap.put("rows", list);
JSONParser.writeJson(josnMap);// 自定义的工具类
}
public String reg(){
logger.error("kkk");
try {
studentService.save(model);
josnMap.put("success", true);
josnMap.put("msg", "注册成功!");
} catch (Exception e) {
e.printStackTrace();
josnMap.put("success", false);
josnMap.put("msg", "注册失败!");
}
try {
ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
ServletActionContext.getResponse().setCharacterEncoding("utf-8");
ServletActionContext.getResponse().getWriter().print(JSON.toJSONString(josnMap));
} catch (IOException e) {
e.printStackTrace();
}
return "toJson";
}
public void setRows(String rows) {
this.rows = rows;
}
public void setPage(String page) {
this.page = page;
}
public Map<String, Object> getJosnMap() {
return josnMap;
}
public void setJosnMap(Map<String, Object> josnMap) {
this.josnMap = josnMap;
}
}
二、BaseAction代码：
import java.lang.reflect.ParameterizedType;
import javax.annotation.Resource;
import org.apache.struts2.ServletActionContext;
import cn.oppo.oa.service.DepartmentService;
import cn.oppo.oa.service.ForumService;
import cn.oppo.oa.service.PrivilegeService;
import cn.oppo.oa.service.RoleService;
import cn.oppo.oa.service.StudentService;
import cn.oppo.oa.service.UserService;
import com.alibaba.fastjson.JSON;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
public abstract class BaseAction<T> extends ActionSupport implements ModelDriven<T> {
/**
*
*/
private static final long serialVersionUID = 1L;
@Resource
protected RoleService roleService;
@Resource
protected DepartmentService departmentService;
@Resource
protected UserService userService;
@Resource
protected PrivilegeService privilegeService;
@Resource
protected ForumService forumService;
@Resource
protected StudentService studentService;
protected T model;
@SuppressWarnings("unchecked")
public BaseAction() {
try {
// 得到model的类型信息
ParameterizedType pt = (ParameterizedType) this.getClass().getGenericSuperclass();
Class<T> clazz = (Class<T>) pt.getActualTypeArguments()[0];
// 通过反射生成model的实例
model = (T) clazz.newInstance();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
public void writeJson(Object object){
try {
String json = JSON.toJSONStringWithDateFormat(object, "yyyy-MM-dd HH:mm:ss");
ServletActionContext.getResponse().setContentType("text/html;charset=utf-8");
ServletActionContext.getResponse().setCharacterEncoding("utf-8");
ServletActionContext.getResponse().getWriter().write(json);
ServletActionContext.getResponse().getWriter().flush();
ServletActionContext.getResponse().getWriter().close();
} catch (Exception e) {
e.printStackTrace();
}
}
public T getModel() {
return model;
}
}
三、页面代码：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
<title>EasyUI框架</title>
<%@ include file="/WEB-INF/jsp/public/common.jspf" %>
<script type="text/javascript">
$(function(){
if(${"#easyui_regForm"}.form('validate')){
$.ajax({
url:'${pageContext.request.contextPath}/student_reg.action',
data:${"#easyui_regForm"}.serialize(),
dataType:'json',
success:function(obj,status,jqXHR){
if(obj.success){
$("#easyui_regDialog").dialog('close');
}
$.message.show({
title:'提示',
msg:obj.msg
});
}
});
}else{
alert('验证失败');
}
});
</script>
</head>
<body class="easyui-layout">
<p data-options="region:'north',split:true" style="height:100px;">aa</p>
<!-- <p data-options="region:'south',split:true" style="height:100px;">bb</p>-->
<p data-options="region:'east',title:'East',split:true" style="width:200px;">cc</p>
<p data-options="region:'west',title:'West',split:true" style="width:200px;">dd</p>
<p data-options="region:'center',title:'center title'" style="padding:5px;background:#eee;">kk</p>
<p class="easyui-dialog" data-options="title:'登陆', modal:true,
closable:false,
toolbar:[{
text:'Edit',
iconCls:'icon-edit',
handler:function(){alert('edit')}
},{
text:'Help',
iconCls:'icon-help',
handler:function(){alert('help')}
}],
buttons:[{
text:'登陆',
handler:function(){alert('登陆')}
},{
text:'注册',
handler:function(){
$('#easyui_regForm input').val('');
$('#easyui_regDialog').dialog('open');
}
}]" >
<table>
<tr>
<td>登陆名称：</td>
<td><input type="text" name="name"/></td>
</tr>
<tr>
<td>登陆密码：</td>
<td><input type="password" name="password"/></td>
</tr>
</table>
</p>
<p id="easyui_regDialog" class="easyui-dialog" data-options="title:'注册', modal:true,
closable:true,
closed:true,
buttons:[{
text:'注册',
handler:function(){
$('#easyui_regForm').form('submit',{
url : '${pageContext.request.contextPath}/student_reg.action',
success : function(data) {
var obj = jQuery.parseJSON(data);
if (obj.success) {
$('#easyui_regDialog').dialog('close');
}
$.messager.show({
title : '提示',
msg : obj.msg
});
}
});
}
},{
text:'取消',
handler:function(){alert('注册')}
}]" >
<form id="easyui_regForm" method="post">
<table>
<tr>
<td>登陆名称：</td>
<td><input type="text" name="loginName" class="easyui-validatebox" data-options="required:true,missingMessage:'用户名称不能为空'"/></td>
</tr>
<tr>
<td>登陆密码：</td>
<td><input id="reg_pwd" type="password" name="password" class="easyui-validatebox" data-options="required:true,missingMessage:'用户密码不能为空'"/></td>
</tr>
<tr>
<td>确定密码：</td>
<td><input type="password" name="repassword" class="easyui-validatebox" data-options="required:true,missingMessage:'确认密码不能为空',validType:'equals[\'#reg_pwd\']'" /></td>
</tr>
</table>
</form>
</p>
</body>
</html>
四、struts2.xml配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 配置为开发模式 -->
<constant name="struts.devMode" value="true" />
<!-- 配置扩展名为action -->
<constant name="struts.action.extension" value="action" />
<!-- 配置主题 -->
<constant name="struts.ui.theme" value="simple" />
<package name="default" namespace="/" extends="json-default">
<interceptors>
<!-- 声明一个拦截器 -->
<interceptor name="checkePrivilege" class="cn.oppo.oa.interceptor.CheckPrivilegeInterceptor"></interceptor>
<!-- 重新定义defaultStack拦截器栈，需要先判断权限 -->
<interceptor-stack name="defaultStack">
<interceptor-ref name="checkePrivilege" />
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
<!-- 配置全局的Result -->
<global-results>
<result name="loginUI">/WEB-INF/jsp/user/loginUI.jsp</result>
<result name="noPrivilegeError">/noPrivilegeError.jsp</result>
</global-results>
<!-- 测试用的action，当与Spring整合后，class属性写的就是Spring中bean的名称 -->
<action name="test" class="testAction">
<result name="success">/test.jsp</result>
</action>
<action name="*_*" class="{1}Action" method="{2}">
<result name="{2}">/WEB-INF/jsp/{1}/{2}.jsp</result>
<!-- 跳转到添加与修改页面 -->
<result name="saveUI">/WEB-INF/jsp/{1}/saveUI.jsp</result>
<!-- 返回list页 -->
<result name="toList" type="redirectAction">{1}_list?parentId=${parentId}</result>
<!-- 返回主页 -->
<result name="toIndex" type="redirect">/index.jsp</result>
<!-- 返回论坛主题 -->
<result name="toShow" type="redirectAction">topic_show?id=${id}</result>
<result name="toTopicShow" type="redirectAction">topic_show?id=${topicId}</result>
<!-- json解析 -->
<result name="toJson" type="json">
<param name="root">josnMap</param>
</result>
<result name="reg">/easyui.jsp</result>
</action>
</package>
</struts>
