Java BCrypt：使用Spring Security的空编码密码

帮助解决问题的代码示例：

问题

在尝试在Spring引导应用程序中实现jwt安全性时，我遇到了以下问题：

当我尝试通过邮递员使用x-www-form-urlencoded登录时，我收到一个错误“坏客户端凭据”，同时我知道凭据是正确的

当我查看日志时，我看到BCrypt发出了一个“空编码密码”警告。这很奇怪，因为当我通过MySQL解释器查看数据库时，我在数据库中看到了正确加密的密码

信息

我正在使用Hibernate构建一个MySQL数据库

编译“org.springframework.security.oauth:spring-security-oauth2:2.3.6.RELEASE”

编译“org.springframework.security:springsecurity jwt:1.0.10.RELEASE”

编译“org.springframework.boot:springbootstarterdatajpa”

Java 1.8.0_212

我尝试的

在开始实施安全性之前，控制器、存储库和MySQL数据库都正常工作

当我在网上搜索这个问题时，有些人建议它与“loadUserByUsername”函数有关。但是当我调试该函数时，我注意到它根本没有被调用

我还尝试了允许程序中的每一条路径并禁用crsf 以防它与访问权有关，但两者都没有改变任何东西<代码>（http.requestMatchers.andMatcher（“/**”）.permitAll（）和（）.csrf（）.disable（）；）

更新：在数据库中放入无用户时，我仍然会收到相同的错误

一些代码：

loadUserByUsername方法：

@Override
public UserDetails loadUserByUsername(String userName) {
    return userRepository.findByUsername(userName)
            .map(user -> new User(
                        user.getUsername(),
                        user.getPassword(),
                        UserRoleAuthority.getAuthorities(user.getRoles())
                ))
            .orElseThrow(() -> new UsernameNotFoundException("Unknown user: " + userName));

}

authenticationprovider和passwordencoder：

@Bean
public DaoAuthenticationProvider getAuthenticationProvider() {
    DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
    authenticationProvider.setUserDetailsService(userDetailsService);
    authenticationProvider.setPasswordEncoder(passwordEncoder());
    return authenticationProvider;
}

@Bean
PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

签名密钥：

@Bean
public JwtAccessTokenConverter jwtTokenEnhancer() {
    JwtAccessTokenConverter result = new JwtAccessTokenConverter();
    result.setSigningKey(signingKey);
    return result;
}

添加新用户：

            userRepository.save(new User()
                            .withUsername("test")
                            .withPassword(passwordEncoder.encode("password"))
                            .withFirst("Admin")
                            .withLast("Nator")
                            .withEmail("test@notadmin.com")
                            .withRole(new HashSet<>(Arrays.asList(Role.Admin, Role.NotAdmin)))
            );

最后，我的控制台：

您必须在configureGlobal方法中添加bCryptPasswordEncoder

@Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .userDetailsService(userDetailsService)
            .passwordEncoder(bCryptPasswordEncoder());
    }

我发现了问题。我使用的是SpringBoot2.1.4.RELEASE，但此设置仅适用于1.5.12.RELEASE。当然，降级不是很好的做法，所以我仍然会尝试让它与2.1.4一起工作。

我认为@ghazouanbadr的解决方案是正确的。尽管如此，我在我的实践项目中采用了不同的方法：

@EnableWebSecurity
@Configuration
public class WebSecurity extends WebSecurityConfigurerAdapter {
    @Autowired
    UserService userService;
    @Autowired
    BCryptPasswordEncoder bCryptPasswordEncoder;

    public WebSecurity(UserService userService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userService = userService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    } 

    @Override // Authorization
    protected void configure(HttpSecurity http) throws Exception {
        ...
    }

    @Override // Authentication
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userService(userService).passwordEncoder(bCryptPasswordEncoder);
   }
}

请注意，创建这个类时，我学习Java才一个月左右。我不太记得安全问题，所以我不该告诉你这是最好的方法。因为我记得曾经处理过同一个问题，所以我认为它可能会指引您正确的方向。

您尝试过基本身份验证吗？您能详细说明一下吗？您是否有以下方法：@Override public void configure（AuthorizationServerEndpoints配置器端点）在类扩展中：AuthorizationServerConfigurerAdapterYes，使用

.tokenStore（tokenStore（））.accessTokenConverter（jwtTokenEnhancer（））.authenticationManager（authManager）其中authManager只是
私有最终身份验证管理器authManager@Suwappertjes拥有一个样本可能会有所帮助。你能把一个样本发布到GitHub吗？我很乐意看一看。谢谢你的提示！我添加了这段代码，但不幸的是没有任何更改
@EnableWebSecurity
@Configuration
public class WebSecurity extends WebSecurityConfigurerAdapter {
    @Autowired
    UserService userService;
    @Autowired
    BCryptPasswordEncoder bCryptPasswordEncoder;

    public WebSecurity(UserService userService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userService = userService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    } 

    @Override // Authorization
    protected void configure(HttpSecurity http) throws Exception {
        ...
    }

    @Override // Authentication
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userService(userService).passwordEncoder(bCryptPasswordEncoder);
   }
}
