Spring安全- BeanCreationException

Question

亲爱的Java专业人士，我正在尝试使用LDAP机制来保护Spring MVC应用程序，使用来自以下链接的说明：https://spring.io/guides/gs/authenticating-ldap/。

但是，我面临的下一个问题是：

通过工厂方法创建名为“org.springframework.beans.factory.BeanCreationException：”的类路径资源org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class: bean实例化的

错误；嵌套异常是org.springframework.beans.BeanInstantiationException:未能实例化javax.servlet.Filter:工厂方法'springSecurityFilterChain‘抛出的异常；嵌套异常为java.lang.NoClassDefFoundError: org/springframework/security/ldap/DefaultSpringSecurityContextSource

我不知道为什么我会犯这个错误。我试着搜索这个论坛，认为发现了类似的问题，但没有成功：https://stackoverflow.com/questions/28616569/error-creating-bean-with-name-springsecurityfilterchain

有人能告诉我我做错了什么吗？提前谢谢。

WebSecurityConfig类是这样的：

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;


@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

 @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
      .authorizeRequests()
      //  .antMatchers("/", "/home").permitAll()
        .anyRequest().authenticated()
        .and()
      .formLogin()
        .loginPage("/login")
        .permitAll()
        .and()
      .logout()
        .permitAll();
  }


  @Override
  public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
        .ldapAuthentication()
        .userDnPatterns("uid={0},ou=people")
        .groupSearchBase("ou=groups")
        .contextSource()
                .url("ldap://localhost:8389/dc=springframework,dc=org")
                .and()
                .passwordCompare()
                .passwordEncoder(new LdapShaPasswordEncoder())
                .passwordAttribute("userPassword");
    }
}

这是MvcConfig类：

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;    

@Configuration
public class MvcConfig implements WebMvcConfigurer {    
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/login").setViewName("login");
  }
}

我遇到了一个类似的问题，尝试了各种方法来消除错误。我想你也遵循了这里的例子：

https://spring.io/guides/gs/authenticating-ldap/

因为我使用的spring引导版本比示例更新，所以没有一个简单的匹配。

最后，经过多次添加和删除依赖项的尝试.我发现缺少的依赖是(对于gradle)：

implementation 'org.springframework.security:spring-security-ldap'

所以在Maven中，应该是这样的：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-ldap</artifactId>
</dependency>
