没有声明可以为元素找到'MVC：注解驱动“

问题描述

我从controller.From返回JSON / XML数据，我需要 @ResponseBody 在我的方法和什么我发现我需要的要求<$ C 启用;注解驱动＆GT：$ C>＆LT MVC。我已经试过各种RND，但我还是坚持！ （

I have the requirement of returning JSON/XML data from my controller.From what i found,I needed @ResponseBody in my method and for that I need <mvc:annotation-driven> enabled. I have tried all sorts of RnD but am still stuck! :(

显然，我的问题出在我servlet.xml文件（该架构得到心不是验证！）
我使用Spring 3.1.1和放大器;已经明确提出春天-MVC-3.1.1.jar在类路径。

Apparently my problem lies in my servlet.xml file (the schema isnt getting validated!)I am using Spring 3.1.1 & have explicitly put in spring-mvc-3.1.1.jar in my classpath.

下面是我的servlet上下文文件样本servlet.xml中：

Here's my servlet-context file sample-servlet.xml:

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/tx                      http://www.springframework.org/schema/tx/spring-tx.xsd
         http://www.springframework.org/schema/mvc-3.1  http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
         http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd">


  <context:component-scan base-package="com.sample.controller"/>
  <mvc:annotation-driven/>

  <!--Use JAXB OXM marshaller to marshall/unmarshall following class-->
  <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" />

  <bean id="xmlViewer"
        class="org.springframework.web.servlet.view.xml.MarshallingView">
    <constructor-arg>
      <bean class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
          <list>
            <value>com.sample.model.SampleClass</value>
          </list>
        </property>
      </bean>
    </constructor-arg>
  </bean>

  <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">

  <property name="viewResolvers">
    <list>
      <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
      </bean>
    </list>
  </property>
</bean>

我的控制器类看起来是这样的：

My controller class looks like this :

@Controller
public class XmlController {

  @RequestMapping(value="/getXml",method = RequestMethod.POST)
  public @ResponseBody AssociateDetail getXml(){
    System.out.println("inside xml controller.....");
    AssociateDetail assoBean=null;

    try{
      AssociateService add=new AssociateService();
      assoBean=add.selectAssociateBean();
    }catch(Exception e){
      e.printStackTrace();
    }

    return assoBean;
  }
}

现在的问题是＆LT; MVC：注解驱动/＆GT; 给出了错误：

Now the problem is <mvc:annotation-driven /> gives error:

CVC-复杂type.2.4.c：匹配通配符是严格的，但没有声明可以为元素被发现。MVC：注解驱动

我试图在这个网站，并建议以后所有的解决方法。已经更新我的架构命名空间，使用Spring 3.1.1和 @ResponseBody 。

And I have tried all the workarounds suggested on this site and beyond. Have updated my schema namespaces, using Spring 3.1.1 and @ResponseBody.

推荐答案

由于错误表明有一些错误的模式声明。您不必在 XSD 申报的。
使用这个来代替。

As the error suggests there's something wrong with the schema declaration. You do not have the xsd s declared.Use this instead.

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"

xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
