Question

我在 spring-servlet.xml 中收到以下错误

通配符匹配严格，但找不到元素“context:component-scan”的声明。

我的 spring-servlet.xml 具有以下内容:

<?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:oauth="http://www.springframework.org/schema/security/oauth2" 
       xmlns:sec="http://www.springframework.org/schema/security"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="

    <!-- Scans the classpath of this application for Spring annotations such 
        as @Component, @Service, @Controller and @Repositry to deploy as beans. For 
        example, the ClaimsService is annotated with @Service("claimsService") which 
        means that spring will automatically create a bean with the name claimsService. 
    -->
    <context:component-scan base-package="org.springframework.security.oauth" />

我已经下载了所有依赖项

问题在于 namespaces 检查添加的 spring jar 的版本和命名空间。特别是对于上下文命名空间的架构位置，

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

请查看spring docs还为 spring security 配置 namespace 。不要添加任何不必要的 namespace
