spring mvc：注释驱动未绑定

mvc:annotation-driven is not bound

提问by Pieter

I get this error when I run a certain Spring Web 3 project in NetBeans:

在 NetBeans 中运行某个 Spring Web 3 项目时出现此错误：

org.xml.sax.SAXParseException; lineNumber: 11; columnNumber: 30; The prefix "mvc" for element "mvc:annotation-driven" is not bound.

org.xml.sax.SAXParseException; 行号：11；列数：30；元素“mvc:annotation-driven”的前缀“mvc”未绑定。

Here's dispatcher-servlet.xml:

这是dispatcher-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:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"

       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <mvc:annotation-driven />
    <context:component-scan base-package="net.myproject.controllers"/>

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/"
          p:suffix=".jsp" />

</beans>

I think I did the appropriate namespace declarations, but obviously I'm still overlooking something. Why am I getting this error?

我想我做了适当的命名空间声明，但显然我仍然忽略了一些东西。为什么我收到这个错误？

It should work like that, and it works for me. The problem might be in your IDE / xml editor. Try ignoring the xml error and run the application.

它应该像那样工作，它对我有用。问题可能出在您的 IDE/xml 编辑器中。尝试忽略 xml 错误并运行应用程序。

This is an IDE Error, Which can be resolved by adding the following to your Spring Dispatcher Servlet

这是一个 IDE 错误，可以通过将以下内容添加到 Spring Dispatcher Servlet 来解决

xmlns:mvc="http://www.springframework.org/schema/mvc"

xmlns:mvc="http://www.springframework.org/schema/mvc"

And also add the following snippet if it is not included in your xml file

如果您的 xml 文件中未包含以下代码段，请添加以下代码段

xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"

xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"

You are probably missing some significant portion of the namespace declaration, as discussed here: http://forum.springsource.org/showthread.php?100397-The-prefix-mvc-for-element-mvc-annotation-driven-is-notbound

您可能遗漏了命名空间声明的一些重要部分，如下所述：http: //forum.springsource.org/showthread.php?100397-The- prefix-mvc-for-element-mvc-annotation-driven-is-未绑定

It does not effect runtime, but the development environment will suffer with similar problems as you describe.

它不会影响运行时，但开发环境会遇到与您描述的类似问题。

I guess it should go this way: http://www.springframework.org/schema/aop/spring-aop-3.0.xsd

我想它应该这样：http: //www.springframework.org/schema/aop/spring-aop-3.0.xsd

Add: xmlns:p="http://www.springframework.org/schema/p"

添加：xmlns:p="http://www.springframework.org/schema/p"

Otherwise xml will not understand the p annotation.

否则 xml 将无法理解 p 注释。
