我想通过创建一个简单的登录屏幕在我的项目中使用Sping Boot Security,但在运行y应用程序时出现这些错误

说明:com.panchmeru_studio.controller.UserController中构造函数的参数1需要一个类型为“org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder”的Bean,但找不到该Bean。
**操作:考虑在您的配置中定义一个类型为org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder的bean。**以下是我的代码。

用户控制器

package com.panchmeru_studio.controller;

import com.panchmeru_studio.entities.ApplicationUser;
import com.panchmeru_studio.repository.ApplicationUserRepository;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/users")
public class UserController {

    private ApplicationUserRepository applicationUserRepository;
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public UserController(ApplicationUserRepository applicationUserRepository,
                          BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.applicationUserRepository = applicationUserRepository;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @PostMapping("/record")
    public void signUp(@RequestBody ApplicationUser applicationUser) {
        applicationUser.setPassword(bCryptPasswordEncoder.encode(applicationUser.getPassword()));
        applicationUserRepository.save(applicationUser);
    }
}

SecurityConfiguration.java

package com.panchmeru_studio.security;

import com.panchmeru_studio.filter.AuthenticationFilter;
import com.panchmeru_studio.filter.AuthorizationFilter;

import com.panchmeru_studio.service.ApplicationUserDetailsService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
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.password.PasswordEncoder;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.CorsConfigurationSource;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;

import static com.panchmeru_studio.constants.SecurityConstants.SIGN_UP_URL;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    private ApplicationUserDetailsService userDetailsService;
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    public SecurityConfiguration(ApplicationUserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder) {
        this.userDetailsService = userDetailsService;
        this.bCryptPasswordEncoder = bCryptPasswordEncoder;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable().authorizeRequests()
                .antMatchers(HttpMethod.POST, SIGN_UP_URL).permitAll()
                .anyRequest().authenticated()
                .and()
                .addFilter(new AuthenticationFilter(authenticationManager()))
                .addFilter(new AuthorizationFilter(authenticationManager()))
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }
    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
        return source;
    }

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

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

}

在“安全配置”类中,不需要以下行:

private BCryptPasswordEncoder bCryptPasswordEncoder;

将其替换为以下方法。下面的方法向Spring容器提供密码编码器bean以实施安全性。

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

在您的控制器中,现在您可以将其自动关联为:

@Autowired    
private BCryptPasswordEncoder bCryptPasswordEncoder;

thigvfpy2#

该错误显示,您没有任何带有密码编码器的Bean。
在您的配置类中,添加该Bean并从SecurityConfiguration的构造函数中删除BCryptPasswordEncoder

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

Replace it with this. The below method is providing the Password Encoder bean to spring container to enforce security.
@Bean
public PasswordEncoder passwordEncoder()
{
    return new BCryptPasswordEncoder();
}
In your controller, now you can autowire this as:
@Autowired    
private PasswordEncoder passwordEncoder;
