嗨，我正在尝试按照本教程http://www.baeldung.com/2011/10/31/securing-a-restful-web-service-with-spring-security-3-1在我的项目中实现 Spring Security -part-3/#config，运行程序时出现以下异常-

org.springframework.beans.factory.BeanCreationException：创建名为“org.springframework.security.filterChains”的bean时出错：bean初始化失败；嵌套异常是 java.lang.NoSuchFieldError: NULL at 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"
    xsi:schemaLocation="

    <!-- <welcome-file-list> -->
    <!-- <welcome-file>index.html</welcome-file> -->
    <!-- </welcome-file-list> -->

</web-app>

我的 webSecurityConfig.xml 看起来像 -

http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd http://www.springframework.org/schema/beans http:// /www.springframework.org/schema/beans/spring-beans-3.2.xsd ">

<http use-expressions="true" entry-point-ref="restAuthenticationEntryPoint">
    <intercept-url pattern="/api/**" access="isAuthenticated()" />

    <sec:form-login authentication-success-handler-ref="mySuccessHandler" />

    <logout />
</http>

<beans:bean id="mySuccessHandler" class="org.baeldung.security.MySavedRequestAwareAuthenticationSuccessHandler" />

<authentication-manager alias="authenticationManager">
    <authentication-provider>
        <user-service>
            <user name="temporary" password="temporary" authorities="ROLE_ADMIN" />
            <user name="user" password="userPass" authorities="ROLE_USER" />
        </user-service>
    </authentication-provider>
</authentication-manager>

我知道这可能是org.springframework.beans.factory.BeanCreationException: Error created bean with name 'org.springframework.security.filterChains' 的重复，但我尝试了该解决方案但无济于事，这可能是因为我仍然是春天的新手。非常感谢任何帮助。

我正在从 org.baeldung.spring 框架中的 SecSecurityConfig.java 加载 websecurityconfig.xml，它看起来像 -

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();
    }

}

查看堆栈跟踪信息，就好像您的类路径中有冲突的框架 jar。当使用 maven usemvn dependency:tree来确定使用了哪些依赖项时，我怀疑您的类路径中有一个较旧的 spring-beans.jar。
