java.lang.IllegalArgumentException:没有为id“null”映射PasswordEncoder[重复]

Question

我是springsecurity的新手，尝试在我的项目中使用springstecurity，因为这个错误不断出现

这是我的道课

package com.voicechat.dao;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;

import com.voicechat.entities.Credentials;
import com.voicechat.entities.Robi_nav;

public interface Robi_Dao_logIn extends JpaRepository<Credentials, Integer> {

    @Query("select c from Credentials c where c.uname = :uname")
    public Credentials getbyUname(@Param("uname") String uname);

}

这是我的凭证类

package com.voicechat.entities;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "credentials")
public class Credentials {

    @GeneratedValue
    @Id
    private int Id;
    private String uname;
    private String password;
    private String role;
    public int getId() {
        return Id;
    }
    public void setId(int id) {
        Id = id;
    }
    public String getUname() {
        return uname;
    }
    public void setUname(String uname) {
        this.uname = uname;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    
    
    
    
    
    public String getRole() {
        return role;
    }
    public void setRole(String role) {
        role = role;
    }
    
    
    public Credentials(int id, String uname, String password, String role) {
        super();
        Id = id;
        this.uname = uname;
        this.password = password;
        role = role;
    }
    public Credentials() {
        super();
        // TODO Auto-generated constructor stub
    }
    @Override
    public String toString() {
        return "Credentials [Id=" + Id + ", uname=" + uname + ", password=" + password + ", role=" + role + "]";
    }
}

我认为错误存在于此代码中

package com.voicechat.config;

import org.springframework.security.crypto.factory.PasswordEncoderFactories;

import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableWebSecurity
public class MyConfig extends WebSecurityConfigurerAdapter {
    
    @Bean
    public UserDetailsService getUserDetailService() {

        return new UserDetailsServiceImpl();

    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();

    }

    @Autowired
    public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception {

        auth.jdbcAuthentication().passwordEncoder(new BCryptPasswordEncoder());

    }

    @Bean
    public DaoAuthenticationProvider provider() {
        DaoAuthenticationProvider daoautpro = new DaoAuthenticationProvider();
        daoautpro.setUserDetailsService(this.getUserDetailService());
        return daoautpro;

    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(provider());

    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("//**").hasRole("ADMIN").and().formLogin().and().csrf().disable();

    }

}

        }
        CustomUserDetails custom=new CustomUserDetails(cred);

最后，这是我的数据库，其中存储了用户名和密码的数据库表

这个错误让我发疯，我做了一切事情来阻止这一点，但这是一次又一次的弹出，基本上我的项目是logIn系统，其中一个uname和密码被手动存储，uname和密码用于登录Web服务

Answer 1

从你的代码中，我可以看到你正在使用Bcrypt编码器。你告诉Spring Security密码是使用它编码的（但实际上你并没有对其进行编码）。

 @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();

    }

在这种情况下，您需要使用BCrypt密码编码器对密码进行编码，就像loadUserByUsername方法中这样

cred.setPassword(bCryptPasswordEncoder.encode(cred.getPassword()))

也在同一个类中自动连接BCryptPasswordEncoder。

@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder

注意：最好在将密码保存到数据库的同时对其进行编码（使用Bcrypt编码器）。所以loadUserByUsername中不需要这样做。

Answer 2

您已经将密码定义为纯字符串，但随后您说要使用BCrypt密码编码器。

如果您阅读密码格式的官方Spring引导留档，您可以看到在数据库中存储密码时需要使用的格式是：

{id}encodedPassword

这意味着在括号中，您需要定义解码密码时要使用的编码器的ID。

下面是som示例密码，其编码器id写在括号之间。

{bcrypt}$2a$10$dXJ3SW6G7P50lGmMkkmwe.20cQQubK3.HZWzG3YB1tlRy.fqvM/BG 
{noop}password 
{pbkdf2}5d923b44a6d129f3ddf3e3c8d29412723dcbde72445e8ef6bf3b508fbf17fa4ed4d6b99ca763d8dc 
{scrypt}$e0801$8bWJaSu2IKSn9Z9kM+TPXfOc/9bdYSrN1oD9qfVThWEwdRTnO7re7Ei+fUZRJ68k9lTyuTeUp4of4g24hHnazw==$OAOec05+bXxvuu/1qZ6NUR+xQYvYv7BeL1QxwRpY5Pc=  
{sha256}97cde38028ad898ebc02e690819fa220e88c62e0699403e94fff291cfffaf8410849f27605abcbc0

这意味着在您的情况下，您的密码需要以以下格式存储：

{bcrypt}YourLongEncryptedPasswordAndNotPlainText.

您得到的错误是因为spring获取您的用户，然后检查用户密码以查看其前缀是什么，所以它可以使用相同的加密对传入密码进行编码，然后与数据库中的密码进行匹配。但是当它查看定义的密码时，没有定义的编码器（没有括号定义编码器），因此它抛出一个异常，表示找不到。

最简单的解决方案是使用bcrypt使用在线服务或在Spring启动中加密密码，然后将加密版本打印到控制台。获取该密码，确保它以 {bcrypt} 开头，然后将其插入数据库。
