问题

当尝试在 Spring Boot 应用程序中实现 jwt-security 时，我遇到了以下问题：

当我尝试通过 Postman 使用 x-www-form-urlencoded 登录时，我收到 "Bad client credentials" 错误，但我知道凭据是正确的.

当我查看我的日志时，我看到 BCrypt 发出了 “空编码密码”警告。这很奇怪，考虑到当我通过 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 MySQL 数据库。

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

编译'org.springframework.security:spring-security-jwt:1.0.10.RELEASE'

编译'org.springframework.boot:spring-boot-starter-data-jpa'

Java 1.8.0_212

我尝试了什么

在开始实施安全之前，控制器、存储库和 MySQL 数据库都运行正常。

当我在网上搜索这个问题时，有人认为它与“loadUserByUsername”功能有关。但是当我调试该函数时，我注意到它根本没有被调用。

我还尝试允许程序中的每条路径并禁用 crsf 以防它与访问权限有关，但两者都没有改变任何东西。 (http.requestMatchers.andMatcher("/**").permitAll().and().csrf().disable();)

更新：将 NO users 放入数据库时，我仍然收到相同的错误。

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));

}

身份验证提供者和密码编码器：

@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)))
            );

以及Http配置：

@Override
public void configure(HttpSecurity http) throws Exception {

    http.requestMatchers()
            .antMatchers("/iungo/*/**")
            .and()
            .authorizeRequests()
            .antMatchers("/iungo/system/**")
            .permitAll()
            .antMatchers("/iungo/**");
}

@Override
public void configure(HttpSecurity http) throws Exception {
    // We don't use this endpoint but we have to define it anyway in order to not enable web security on the whole application.
    http
            .userDetailsService(userDetailsService)
            .requestMatchers()
            .antMatchers("/oauth/authorize");
}

最后，我的控制台：

【解决方案1】：

我面临着完全相同的问题。在我的情况下，原因是我的 CustomUserDetails 类构造函数，它没有为类设置密码，所以它总是为空。

此回答者的功劳： why spring security gives empty password to password encoder?

【解决方案2】：

我认为@ghazouanbadr 的解决方案是正确的。虽然，我在实践项目中的实现方式有所不同：

@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，当我创建这个课程时，我才刚开始学习 Java 一个月。不要对安全性有太多了解，所以我不能告诉你这是最好的方法。因为我记得处理过同样的问题，所以我认为它可能会引导您朝着正确的方向前进。

【解决方案3】：

我发现了问题。我使用的是 Spring boot 2.1.4.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 一起使用。

【解决方案4】：

你必须在 configureGlobal 方法中添加 bCryptPasswordEncoder

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