找不到org.springframework.security.authentication.encoding.passwordencoder的类文件

Question

我用Spring-boot和spring security制作了一个简单的restAPI，实现了基本的身份验证。我想使用inMemoryAuthentication和bcryptPasswordEncoder，但由于某种原因，我的编译器在错误的地方查找passwordEncoder，请参阅标题vs Security.Crypto.Password.passwordEncoder。

我的基本身份验证如下所示：

import org.springframework.context.annotation.Bean;
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;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;    
Configuration
    @EnableWebSecurity
    public class BasicAuthConfig extends WebSecurityConfigurerAdapter {
      // Authentication : User --> Roles
      // NoOpPasswordEncoder has been deprecated in Spring security so {noop} is being used to avoid errors
      protected void configure(AuthenticationManagerBuilder auth)
        throws Exception {
        auth.inMemoryAuthentication()
          .passwordEncoder(passwordEncoder())
          .withUser("user1")
            .password("{noop}secret1")
            .roles("USER")
          .and().withUser("admin1")
            .password("{noop}secret1")
            .roles("USER", "ADMIN");
      }

      // Authorization : Role -> Access
      protected void configure(HttpSecurity html" target="_blank">http) throws Exception {
        http
          .httpBasic()
          .and().authorizeRequests()
            .antMatchers("/tokenservice/**")
              .hasRole("USER")
            .antMatchers("/**")
              .hasRole("ADMIN")
          .and().csrf()
          .disable()
            .headers()
            .frameOptions()
          .and().disable()
            .sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
      }
      @Bean
      public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
      }
    }

我在尝试编译时遇到以下错误：

错误：（21,7）Java：无法访问未找到org.springframework.security.authentication.encoding.passwordencoder的org.springframework.security.authentication.encoding.passwordencoder类文件

忽略密码前面的{noop}。有没有在没有密码编码器的情况下进行测试。

我对Spring、gradle和java都很陌生。我可能用错了Spring版本吗？如果是这样的话，我该怎么修理呢？

如果您使用的是最新的spring-security版本，您应该在org.springframework.security.crypto.password包中找到passwordencoder类。

已不推荐使用org.springframework.security.authentication.encoding.passwordencoder包中的passwordencoder
