Question

我想进行身份验证，并使用密码加密，当我使用PasswordEncoder（）和setPasswordEncryptor（）时，出现以下错误：PasswordEncoder（）：无法实例化PasswordEncoder和setPasswordEncryptor（）：方法setPasswordEncryptor未为类型PasswordEncoder定义（StrongPasswordEncryptor）。我不知道该怎么办，所以我搜索太多了。感谢大伙们！

    this.authenticationProvider = authenticationProvider;

    DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
    daoAuthenticationProvider.setPasswordEncoder(passwordEncoder);
    daoAuthenticationProvider.setUserDetailsService(userDetailsService);

    httpSecurity.csrf().disable();
    httpSecurity.headers().frameOptions().disable();
}




}

Answer 1

尝试以下代码段。应该可以。

@Bean
public PasswordEncoder encoder() {
    return new BCryptPasswordEncoder(11);
}

@Bean
public DaoAuthenticationProvider authProvider(UserDetailsService userDetailsService) {
    final DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
    authProvider.setUserDetailsService(userDetailsService);
    authProvider.setPasswordEncoder(encoder());
    return authProvider;
}

Answer 2

使用它：Spring Boot 2

@Bean(name = "passwordEncoder")
@Qualifier("passwordEncoder")
public PasswordEncoder passwordEncoder() {
    return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}

Spring Boot Security中的密码编码器
