DWR开发流程

(1)将下载到的dwr.zip解压

(2)将解压路径下WEB-INF/lib路径下的dwr.jar,commons-logging-1.0.4.jar复制到自己的web应用对应路径下

(3)修改web.xml文件

<servlet>
	<servlet-name>dwr-invoker</servlet-name>
	<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
	<init-param>
		<!--指定DWR是否处于调试状态,只有处于调试状态才有调试页面-->
		<param-name>debug</param-name>
		<param-value>true</param-value>
	</init-param>
</servlet>
<servlet-mapping>
	<servlet-name>dwr-invoker</servlet-name>
	<url-pattern>/wangdwr/*</url-pattern>
</servlet-mapping>

(4) 写类

(5)在WEB-INF路径下增加dwr.xml文件

<allow>
	<create creator="new" javascript="hello">
		<param name="class" value="dwr.HelloDwr"/>
	</create>
	<create creator="new" javascript="json">
		<param name="class" value="dwr.JSONShow"/>
	</create>
	<convert match="dwr.Person" converter="bean"/>
	<convert match="dwr.Cat" converter="object">
		<param name="force" value="true"/>
	</convert>
</allow>
<signatures>
	<![CDATA[
	import java.util.List;
	import dwr.HelloDwr;
	import dwr.Person;
	HelloDwr.sendListNoGeneric(List<Person>);
	]]>
		</signatures>

(6)部署到服务器，访问http://localhost:8080/dwr/wangdwr/index.html可看到调试页面

(7)使用生成的javascript对象时要导入对应的javascript代码库:

<script type='text/javascript' src='/dwr/wangdwr/engine.js'></script>
 <script type='text/javascript' src='/dwr/wangdwr/interface/hello.js'></script>

如果要使用工具还要导入相应工具库:

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