DWR Spring 注解 整合

1、添加相应jar包

2、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
 xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 <servlet>
  <servlet-name>dwr-invoker</servlet-name>
  <servlet-class>
   org.directwebremoting.servlet.DwrServlet
  </servlet-class>
  <init-param>
   <param-name>config-dwr</param-name>
   <param-value>
    /WEB-INF/dwr.xml
   </param-value>
  </init-param>
  
  <init-param>
   <param-name>debug</param-name>
   <param-value>true</param-value>
  </init-param>
  <!--
  <init-param>
   <param-name>activeReverseAjaxEnabled</param-name>
   <param-value>true</param-value>
  </init-param>
  <init-param>
     <param-name>org.directwebremoting.extend.Remoter</param-name>
     <param-value>
      com.eastcom.sspm.servlet.DWRSessionService
     </param-value>
   </init-param>
    -->
 </servlet>
 <servlet-mapping>
  <servlet-name>dwr-invoker</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
 </servlet-mapping>

 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/applicationContext.xml</param-value>
 </context-param>
 <listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
 </listener>

 <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 

3、增加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>

<!-- 创建实体bean 供DWR转换成js-->
 <convert converter="bean"
  match="com.eastcom.sgs.bean.user.UserInfo">
 </convert>
 <convert converter="bean"
   match="com.eastcom.sgs.common.AllistRange">
 </convert>
 
<!--  <create creator="new" javascript="UserInfoAction">
  <param name="class"
   value="com.eastcom.sgs.action.user.UserInfoAction" />
 </create>
 -->

<!-- 因为此处是整合spring 来做的，所以creator = 'spring'  javascript="UserInfoAction"

       表示实例转换成javascript语言后以UserInfoAction 命名,前台页面可以通过(<script type="text/javascript"

       src=<%=basePath%>'/dwr/interface/UserInfoAction.js'/>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中的某个bean的id值，此处使用spring注解来自动生成bean，默认为类名字 首个字母小写

-->

 <create creator="spring" javascript="UserInfoAction">
  <param name="beanName"
   value="userInfoAction" />
 </create>
 </allow>
</dwr>

 

4、创建一个实体bean 供DWR转换成js，

 

5、

在类中使用注解驱动ioc

@Controller
public class UserInfoAction {

 

 @Autowired
 private IUserInfoManager userInfoManager;

 

无需写 setter/getter方法 spring 容器 自动生成id为 userInfoAction 的bean

 

}

 

 

@Service
public class UserInfoManagerImpl implements IUserInfoManager {
 @Autowired
 private IUserInfoDao userinfoDao;

 

}

 

@Repository
public class UserInfoDaoImpl implements IUserInfoDao {

 

}

 

在applicationContext.xml 中配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop" xmlns:task="http://www.springframework.org/schema/task"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
       http://www.springframework.org/schema/task
       http://www.springframework.org/schema/task/spring-task-3.0.xsd
       http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

<!-- 对web包中的所有类进行扫描，以完成bean创建和自动依赖注入的功能-->

 <context:component-scan base-package="com.eastcom.sgs" />
 <context:annotation-config /><!-- 隐藏注册了多个对注释进行解析处理的处理器-->

</beans>

6、前台页面处理
