Java Spring安全性-找不到Spring NamespaceHandler--安全性

我有异常：org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题：找不到XML架构命名空间的Spring NamespaceHandler[ 有问题的资源：ServletContext资源[/WEB-INF/spring/security.xml]

在谷歌的几分钟里，比如说我，我需要添加依赖项——spring安全配置。我有最新版本4.2.1，但有一个例外

maven

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>

org.springframework.security
spring安全配置
4.2.1.1发布

这可能是一个未解决的依赖项。如果看不到Maven pom或项目配置，Spring Security的最低要求是：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>

org.springframework.security
spring安全网
4.2.1.1发布
org.springframework.security
spring安全配置
4.2.1.1发布

如果您使用的是Spring工具套件或Eclipse，请确保右键单击您的项目，然后选择

Maven->Update project

，并执行完整的

clean安装
