Two different ways

First, configure directly in the spring configuration file Applictioncontext

Second, separate dwr.xml file configuration

Test class:

Package com.test; public class Test {public string test (string name) {System.out.println ("---------"), return "Hello" + name + "!!!!!"; } }

The first way:

Applicationcontext.xml

<?xml version= "1.0" encoding= "UTF-8"?> <beans "xmlns=" 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 Forwarding with Org.directwebremoting.spring.DwrSpringServlet

Second Kind

Applicationcontext.xml (as with the general Spring bean Configuration)

<?xml version= "1.0" encoding= "UTF-8"?> <beans "xmlns=" 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 Call name)" > <param name= "Beanname" Value= "Test (ID of the corresponding bean in spring configuration)"/> </create> </allow> </dwr>
