</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>dwr的配置文件如下：
<dwr>
<allow> <create creator="spring" javascript="login" scope="session">
<param name="beanName" value="validateLog" />
<include method="login"/>
</create>
<convert match="edu.casia.briefing.domain.User" converter="bean">
<param name="include" value="username,password"></param>
</convert>
<!-- this is a bad idea for live, but can be useful in testing -->
<convert converter="exception" match="java.lang.Exception" />
<convert converter="bean" match="java.lang.StackTraceElement" />
</allow>
</dwr>
spring的相应的配置文件如下： <bean id="validateDao" class="edu.casia.briefing.login.dao.impldao.ValidateDaoImpl">

</bean>
<bean id="loginService" class="edu.casia.briefing.login.service.implservice.LoginServiceImpl">

</property>
</bean>
<bean id="validateLog" class="edu.casia.briefing.login.dwr.ValidateLogin">
<property name="lservice" ref="loginService"></property>
</bean> 后台的处理类如下：
package edu.casia.briefing.login.dwr;import edu.casia.briefing.login.service.interservice.LoginService;public class ValidateLogin {
private LoginService lservice;
public ValidateLogin(){}
public LoginService getLservice() {
return lservice;
}
public void setLservice(LoginService lservice) {
this.lservice = lservice;
}
public boolean login(String userName,String password){
System.out.println("haohaohao");
return lservice.validateLogin(userName, password);
}
}
前台：的dwr代码如下：
