私はSpringプロジェクトで認証プロバイダとしてmongodbを実装しようとしています。 これはinMemory認証の魅力のように機能します。ここ は私がやったことです:Springセキュリティ:mongodb認証プロバイダ

セキュリティ設定:

package com.myBlog.Config; 

import org.springframework.beans.factory.annotation.Autowired; 
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 SecurityConfig extends WebSecurityConfigurerAdapter { 

    @Autowired 
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception { 
     auth.userDetailsService(userDetailsService()); 
    } 

    @Override 
    protected void configure(HttpSecurity http) throws Exception { 
     http.authorizeRequests() 
       .antMatchers("/login", "/style/**").permitAll() 
       .antMatchers("/", "/**/**").permitAll().and() 
       .formLogin() 
       .defaultSuccessUrl("/home"); 


    } 


} 

ユーザーモデル:

package com.myBlog.Models; 

import org.springframework.data.mongodb.core.index.Indexed; 
import org.springframework.data.mongodb.core.mapping.Document; 

@Document(collection="user") 
public class User { 

    private String id; 
    @Indexed(unique = true) 
    private String username; 
    private String password; 

public String getUsername() { 
    return username; 
} 

public void setUsername(String username) { 
    this.username = username; 
} 

public String getPassword() { 
    return password; 
} 

public void setPassword(String password) { 
     this.password = password; 


    } 
} 

POJO

package com.myBlog.Services; 

import com.myBlog.Models.User; 
import org.springframework.security.core.GrantedAuthority; 
import org.springframework.security.core.userdetails.UserDetails; 

    import java.util.Collection; 

/** 
* Created by root on 25/09/16. 
*/ 
public class SecUserDetails implements UserDetails { 

    private User user; 
    public SecUserDetails(User user) { 
     this.user = user; 
    } 
@Override 
public Collection<? extends GrantedAuthority> getAuthorities() { 
    return null; 
} 

@Override 
public String getPassword() { 
    return null; 
} 

@Override 
public String getUsername() { 
    return null; 
} 

@Override 
public boolean isAccountNonExpired() { 
    return false; 
} 

@Override 
public boolean isAccountNonLocked() { 
    return false; 
} 

@Override 
public boolean isCredentialsNonExpired() { 
    return false; 
} 

@Override 
public boolean isEnabled() { 
    return false; 
} 

}

ユーザーレポsitory:

package com.myBlog.Services; 


import com.myBlog.Models.User; 
import org.springframework.data.repository.CrudRepository; 
import org.springframework.stereotype.Service; 

@Service 
public interface UserRepository extends CrudRepository<User, String> { 

    User findByUsername(String username); 

}

任意のアイデアをしてください? それが認証プロバイダとしてMongodbを実装する正しい方法であるかどうかも知っていますか?

あなたの設定ではUserRepositoryが検出されていないようですが、提供された情報から理由を理解するのは難しいです。 –

必要な情報はどうですか?私はそれを提供することができます –

UserRepositoryは、春には、このインタフェースのプロキシインスタンスを作成しない限り、直接初期化することはできませんだけのインタフェースです。設定クラスに@EnableMongoRepositoriesと注釈を付けます。
