Question

尊敬的Java专业人员，我正在尝试使用来自以下链接的说明使用LDAP机制保护Spring-boot MVC应用程序：https://spring.io/guides/gs/authenticating-ldap/

但是，我面临下一个问题：

org.springframework.beans.factory.BeanCreationException：在类路径资源[org / springframework / security / config / annotation / web / configuration / WebSecurityConfiguration.class]中创建名称为'springSecurityFilterChain'的bean时出错：通过工厂实例化Bean方法失败；嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[javax.servlet.Filter]：工厂方法'springSecurityFilterChain'抛出了异常；嵌套的异常是java.lang.NoClassDefFoundError：org / springframework / security / ldap / DefaultSpringSecurityContextSource

我不知道为什么会出现此错误。我试图在这个论坛上搜索，以为发现了类似的问题，但是没有成功： https://stackoverflow.com/questions/28616569/error-creating-bean-with-name-springsecurityfilterchain

有人能建议我做错了吗？预先感谢。

这是WebSecurityConfig类的外观：

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");
  }
}

我遇到了类似的问题，并尝试了各种方法来消除错误。我想您也遵循此处给出的示例：

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

由于我使用的spring boot版本比示例新，因此没有直接的匹配。

最终，在尝试添加和删除依赖项之后，我发现缺少的依赖项是（用于gradle）：

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

因此在Maven中，它应该类似于：

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