本文深入探讨了如何将Spring MVC与Direct Web Remoting（DWR）进行整合，通过配置web.xml和mvc-servlet.xml文件，实现前端与后端的高效交互。重点介绍了如何设置欢迎文件、上下文参数、监听器、servlet及其映射，以及DWR的配置和注解使用，确保前后端数据的无缝传递。

	<bean

</beans>

注意

<dwr:annotation-config id="dwrId" />

要有id

<bean
		class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>

需要加入

java

package com.wxl.app.service;

import org.directwebremoting.annotations.RemoteMethod;
import org.directwebremoting.annotations.RemoteProxy;
import org.springframework.stereotype.Service;

@Service
@RemoteProxy(name = "springService")
public class SpringService {
	@RemoteMethod
	public Person savePerson(Person p) {
		System.out.println(p);
		return p;
	}

	@RemoteMethod
	public String test(String p) {
		System.out.println(p);
		return p;
	}
}
