Question

这是我唯一的配置类：

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled=true, jsr250Enabled=true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .ldapAuthentication()
                .userSearchBase("cn=users,cn=accounts")
                .userSearchFilter("uid={0}")
                .contextSource()
                    .url("ldap://1.2.3.4/dc=dev");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // TODO: fix frontend
        http.csrf().disable();
    }
}

我没有其他配置类或注释。我的application.properties只设置server.port和一些日志记录级别。如果我注释掉ldap代码并使用，例如inMemoryAuthentication，那么一切正常。

我已经尝试过使用.ldapAuthentication()在线我可以找到的每个例子，包括这里的一些相关问题，并且它们都会导致此错误。有什么问题？

我相信所有相关的依赖都来自这些方面：

compile 'org.springframework.boot:spring-boot-starter-security'
compile 'org.springframework.boot:spring-boot-starter-web'

堆栈跟踪的一小部分：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is org.springframework.security.config.annotation.AlreadyBuiltException: This object has already been built

添加<?php echo $_GET['Confirm']; //Get value of the choosen 'Confirm' input ?>将按照Ali的建议解决。
