无法找到“org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"类型的bean [英] a bean of type 'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder' that could not be found

问题描述

我想通过创建一个简单的登录屏幕在我的项目中使用 Spring Boot Security，但即使我为 BCryptPasswordEncoder 定义了一个 bean，我也会收到这些错误.完整的错误是

I want to use Spring Boot Security in my project by creating a simple login screen but i get these error even i define a bean for BCryptPassworrdEncoder. The full error is

字段 bCryptPasswordEncoder incom.mahmut.demoemployee.application.dao.Imp.UserDaoImp 需要一个 bean类型'org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder'找不到.

这是我的代码.

package com.mahmut.demoemployee.application.dao.Imp;
    //Some imports

            @Component
        public class UserDaoImp implements UserDao {

            @Autowired
            UserRepository userRepository;

            @Qualifier("roleRepository")
            @Autowired
            RoleRepository roleRepository;

            @Autowired
            private BCryptPasswordEncoder bCryptPasswordEncoder;

            @Override
            public User save(User user) {
                user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));
                user.setActive(1);
                Role userRole = roleRepository.findByRole("ADMIN");
                user.setRoles(new HashSet<Role>(Arrays.asList(userRole)));
                return userRepository.save(user);
            }

            @Override
            public User findUserByEmail(String email) {
                return userRepository.findByEmail(email);
            }

            @Override
            public List<User> findAll() {
                return (List<User>) userRepository.findAll();
            }
        }

这是我的配置类.

    package com.mahmut.demoemployee.application.config;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;


@Configuration
public class WebMvcConfig extends WebSecurityConfigurerAdapter {

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

}

安全配置类

 package com.mahmut.demoemployee.application.config;
//Lots of import here

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

    @Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

    @Autowired
    private DataSource dataSource;



    @Value("${spring.queries.users-query}")
    private String usersQuery;

    @Value("${spring.queries.roles-query}")
    private String rolesQuery;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.
                jdbcAuthentication()
                .usersByUsernameQuery(usersQuery)
                .authoritiesByUsernameQuery(rolesQuery)
                .dataSource(dataSource)
                .passwordEncoder(bCryptPasswordEncoder);
    }

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

        http.
                authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/login").permitAll()
                .antMatchers("/registration").permitAll()
                .antMatchers("/admin/**").hasAuthority("ADMIN").anyRequest()
                .authenticated().and().csrf().disable().formLogin()
                .loginPage("/login").failureUrl("/login?error=true")
                .defaultSuccessUrl("/admin/home")
                .usernameParameter("email")
                .passwordParameter("password")
                .and().logout()
                .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
                .logoutSuccessUrl("/").and().exceptionHandling()
                .accessDeniedPage("/access-denied");
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web
                .ignoring()
                .antMatchers("/resources/**", "/static/**", "/css/**", "/js/**", "/images/**");
    }

}

我尝试的是;

我尝试使用 PasswordEncoder 而不是 BCryptPasswordEncoder 给出了与密码编码器相同的错误.我删除了 @Component 注释并编写了 @Service 它也给出了相同的错误.我不知道是否有必要，但这是我的 pom.xml 文件.只有必要的依赖项.

I tried to use PasswordEncoder instead of BCryptPasswordEncoder gives the same error with Password Encoder. I remove the @Component annotation and write @Service it gives same error as well. I dont know if its necessary but here is my pom.xml file. There are only essential dependencies.

我不知道我还能做什么.我检查了很多有类似错误的网站并做了，但结果是一样的.

I dont know what else i could do. I checked lots of websites with similiar errors and did them but result is same.

推荐答案

您使用了多个扩展 WebSecurityConfigurerAdapter 的类.在 WebMvcConfig 类上设置 order.

You used multiple class which extends of WebSecurityConfigurerAdapter. Set order on WebMvcConfig class.

@Configuration
@Order(1)
public class WebMvcConfig extends WebSecurityConfigurerAdapter {
    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
        return bCryptPasswordEncoder;
    }
}
