在web.xml中添加代码：
<!-- 配置DWR -->
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>classes</param-name>
<param-value>java.lang.Object</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
在WEB-INF目录下加入dwr.xml 代码如下:
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
"http://www.getahead.ltd.uk/dwr//dwr20.dtd">
<dwr>
<allow>
<create creator="spring" javascript="DwrAction" > <!--方法名称-->
<param name="beanName" value="dwrAction"></param> <!--对应applicationContext.xml中bean的名称-->
</create>
</allow>
</dwr>
applicationContext.xml中bean的配置如下:
<!-- DWR 配置 -->
<bean name="dwrdao" class="com.jjq.oa.dao.impl.DwrDaoImpl">
<property name="hibernateTemplate">
<ref bean="hibernateTemplate" />
</property>
</bean>
<bean name="dwrAction" class="com.jjq.oa.web.struts.action.DwrAction">
<property name="dwrdao">
<ref bean="dwrdao" />
</property>
</bean>
action中的代码如下(DwrAction.JAVA)
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:48:07
*/
package com.jjq.oa.web.struts.action;
import java.util.List;
import com.jjq.oa.DwrDao;
import com.jjq.oa.dao.po.Activitiestypes;
public class DwrAction {
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:48:07
* @note
*/
DwrDao dwrdao;
public void setDwrdao(DwrDao dwrdao) {
this.dwrdao = dwrdao;
}
public String [] getActivitiestypes(){
List activitiestypes =dwrdao.activitiestypes();
String result[]= new String[activitiestypes.size() * 2];
Object [] object=null;
int b=0;
for(int i=0,j=0;i<activitiestypes.size();i++){
object = (Object [])activitiestypes.get(i);
result[j]=((Integer)object[0]).intValue()+"";
result[j+1]=(String)object[1];
System.out.println(result[j]+"|"+result[j+1]);
j=j+2;
}
return result;
}
}
接口文件代码如下(DwrDao.java):
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:51:19
*/
package com.jjq.oa.dao;
import java.util.List;
public interface DwrDao {
/**
*
*@author 季枫
*@create-time 2009-2-6 下午02:52:48
*@note 活动类别
*/
public List activitiestypes();
}
Dao的实现类代码如下(DwrDaoImpl.java):
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:53:27
*/
package com.jjq.oa.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.jjq.oa.dao.DwrDao;
import com.jjq.oa.dao.po.Activitiestypes;
public class DwrDaoImpl extends HibernateDaoSupport implements DwrDao{
public List activitiestypes() {
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:53:27
* @note
*/
List rs = getHibernateTemplate().find("select id,name from Activitiestypes");
return rs;
}
/**
* @creator 季枫
* @create-time 2009-2-6 下午02:53:27
* @note
*/
}
前台JSP调用的代码如下:
<script>
DwrAction.getActivitiestypes(back); //活动类别
function back(arr){
alert(arr.length);
var str1="<select><option value=\'999\'>请选择</option>";
for (i=0,j=1;i<arr.length;i++)
{
str1+="<option value=\'"+arr[i]+"\'>"+arr[j]+"</option>";
j=j+2;
i++;
}
str1+="</select>";
alert(str1);
classid.innerHTML=str1;
}
</script>
