找不到元素'mvc:annotation-driven'的声明
我需要从控制器返回JSON / XML数据。从我发现的结果来看,我需要@ResponseBody
在我的方法中<mvc:annotation-
driven>启用它。我已经尝试过各种RnD,但仍然遇到问题!:(
显然我的问题出在我的servlet.xml文件中(该模式未得到验证!),我正在使用Spring 3.1.1,并且已在我的类路径中明确放入spring-
mvc-3.1.1.jar。
这是我的servlet上下文文件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>
我的控制器类如下所示:
@Controllerpublic 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<mvc:annotation-driven />
给出错误:
cvc-complex-type.2.4.c:匹配的通配符是严格的,但是找不到元素“ mvc:annotation-driven”的声明。
而且,我已经尝试了本网站及其他网站上建议的所有解决方法。使用Spring 3.1.1和更新了我的架构名称空间@ResponseBody
。
回答:
如错误所示,架构声明有问题。您没有xsd
声明。改用它。
