springmvc controller中返回已经生成的xml数据

1.上代码

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class XmlController {

@RequestMapping(value = "/xml", produces={"application/xml; charset=UTF-8"}, method = { RequestMethod.GET,
RequestMethod.POST })
@ResponseBody
public String xml(HttpServletRequest request, HttpServletResponse response)
throws Exception {
String xmlData = "<person>"
+ "<name>tom</name>"
+ "<age>17</age>"
+ "</person>";
return xmlData;
}
}

2.springmvc配置文件如下：<?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:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.yitong.controller"/>
<mvc:annotation-driven/>

<!-- 通过mvc:resources设置静态资源，这样servlet就会处理这些静态资源，而不通过控制器 -->
<!-- 设置不过滤内容，比如:css,jquery,img 等资源文件 -->
<mvc:resources location="/*.html" mapping="/**.html" />
<mvc:resources location="/css/*" mapping="/css/**" />
<mvc:resources location="/js/*" mapping="/js/**" />
<mvc:resources location="/images/*" mapping="/images/**" />
<!--
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
-->
</beans> 3.访问：
