DWR Ext 加载数据

复制代码 代码如下:

public class CustomerManagerImpl extends HibernateDaoSupport implements CustomerManager {
public PageModel allCustomers() {
PageModel pageModel = new PageModel();
List datas = new ArrayList();
int total ;

String hql = "from Customer";
datas = this.getHibernateTemplate().find(hql);
String countHql = "select count(*) from Customer";
total = ((Long)this.getSession().createQuery(countHql).uniqueResult()).intValue();

pageModel.setDatas(datas);
pageModel.setTotal(total);
return pageModel;
}
}

复制代码 代码如下:

var store = new Ext.data.Store({
/https://img.qb5200.com/download-x/data:... 这里有DWR调用直接得到
reader:new Ext.data.JsonReader({id:"sn"},fields), //List数据
sortInfo:{field:'name', direction:'ASC'}// 排序信息
});

//DWR+EXT整合的句子， store.loadData(dataslist);加载数据
/https://img.qb5200.com/download-x/data返回的是PageModel类，属性为total,datas(List数据类型)
//这里不用建立函数，直接执行
JCustomerManager.allCustomers(function(data) {
var total = data.total;
var dataslist=data.datas; //数据为List类型
store.loadData(dataslist); //加载数据
});

复制代码 代码如下:

<dwr>
<allow>
<!-- dwr+spring 注入方式-->
<create creator="spring" javascript="JCustomerManager">
<param name="beanName" value="customerManager"/>
</create>
<!-- 使用到的类要用到转换器-->
<convert match="com.graduate.crm.PageModel" converter="bean"></convert>
<convert match="com.graduate.crm.model.CompanyCustomer" converter="bean"></convert>
</allow>
