java - cvc-复杂类型.2.4.a : Invalid content was found starting with element 'beans'

Question

我是这个概念的新手，我不知道错误是什么，所以有人帮我纠正这个错误。我在我的 xml 中使用与在我的 pom 文件中相同的版本。 (我正在使用 maven，spring boot 和 eclipse 之间)。

错误是

Answer 1

您已将 bean 添加到 pom.xml，而应该将其添加到 spring.xml。您的 POM 应如下所示

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

你的 spring.xml 应该是这样的:

 <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"

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

<context:component-scan base-package="com.example.springmvcforms" />
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>
