DWR+SPRING整合

 

1 dwr.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd">

<dwr>

 <allow>
  <create javascript="DWRUser" creator="spring">
   <param name="beanName" value="userBiz"></param>

   <include method="loadById"/><!--需要对外暴露的方法-->
  </create>
 </allow>

</dwr>
 

creator属性的值可以是new,struts,spring......  spring类型允许你通过spring来创建实例.因为此处是整合spring来做的，所以设置成“spring”，javascript="DWRUser" 表示实例转换成javascript语言后以DWRUser来命名，前台页面可以通过代码（<script type='text/javascript' src='../../dwr/interface/DWRUser.js'></script>）来调用。param元素的name属性值可以是class,beanName等，此处用beanName,value的值是定义在applicationContext.xml中某个bean的id值。

 

 <bean id="userBiz" class="com.shaccp.biz.UserBizImpl">
  <property name="userDAO" ref="userDAO"></property>
 </bean>

 

2 实体类  userDAO是spring注入进来

public class UserBizImpl implements UserBiz {

 private UserDAO userDAO;

 

 public void setUserDAO(UserDAO userDAO) {
  this.userDAO = userDAO;
 }

 

 public List getByPage(String name, int pageNo, int pageSize) {
  return userDAO.findByPage(name, pageNo, pageSize);
 }

 public void add(User u) {
  userDAO.add(u);

 }

 public User loadById(int id) {
  return userDAO.getUserById(id);
 }

 public void update(User user) {
  userDAO.update(user);

 }

 public void delete(int uid) {
  userDAO.delete(uid);

 }

}

 

 

3 在视图页面中调用
先导入javascript，每个文件的功能这里不再详述

<script type='text/javascript' src='/userssh/dwr/interface/DWRUser.js'></script>
  <script type='text/javascript' src='/userssh/dwr/engine.js'></script>

  <script type='text/javascript' src='/userssh/dwr/util.js'></script>

具体调用代码略
