Java Spring安全性-org.springframework.beans.factory.BeanCreationException:创建名为'；org.springframework.security.filterChains'；

您好，我正试图通过遵循本教程在我的项目中实现spring安全性，我在运行程序时遇到以下异常-

org.springframework.beans.factory.BeanCreationException:错误 正在创建名为“org.springframework.security.filterChains”的bean： bean初始化失败；嵌套异常是 java.lang.NoSuchFieldError:在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean（AbstractAutowireCapableBeanFactory.java:532）

我的web.xml看起来像-

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

查看stacktrace信息，似乎类路径中存在冲突的框架JAR。当使用maven使用

mvn dependency:tree

来确定使用了哪些依赖项时，我怀疑在您的类路径中有一个旧的spring-beans.jar

在加载webSecurityConfig.xml文件时，是否可以显示/发布？根据当前信息判断，它没有被加载。

package org.baeldung.spring;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

@Configuration
@ImportResource({ "classpath:webSecurityConfig.xml" })
@ComponentScan("org.baeldung.security")
public class SecSecurityConfig {

    public SecSecurityConfig() {
        super();
    }

}
