Ajax------------- spring+dwr整合

两种方式

一、直接在spring配置文件applictionContext里配置

二、单独的dwr.xml文件配置

测试类:

package com.test;
public class Test {
	public String test(String name) {
		System.out.println("---------");
		return "hello " + name + " !!!!!";
	}
}

第一种方式:

applicationContext.xml

<?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:dwr="http://www.directwebremoting.org/schema/spring-dwr"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
    http://www.directwebremoting.org/schema/spring-dwr
    http://www.directwebremoting.org/schema/spring-dwr-2.0.xsd">
	<bean id="test" class="com.test.Test">
		<dwr:remote javascript="TestDwr">
			<dwr:include method="test"/>
		</dwr:remote>
	</bean>
</beans>

dwr转发用 org.directwebremoting.spring.DwrSpringServlet

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">
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<!--Spring ApplicationContext 载入 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>dwr</servlet-name>
		<servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>
		<init-param>
			<param-name>debug</param-name>
			<param-value>true</param-value>
		</init-param>
	<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dwr</servlet-name>
		<url-pattern>/dwr/*</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

第二种

applicationContext.xml(和一般的spring bean配置一样)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
dwr-2.0.xsd">
	<bean id="test" class="com.test.Test">
	</bean>
</beans>

dwr.xml

<?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 creator="spring" javascript="TestDwr(javascript调用名)">
      <param name="beanName" value="test(spring配置中对应的bean的id)"/>
    </create>
  </allow>
</dwr>

web.xml

dwr转发用
