我在这里问了有关最新的Spring框架和基于代码的配置的问题

initializer

public class AppInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { SecurityConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { MvcConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
}

MVC config

    @EnableWebMvc
    @ComponentScan({ "com.appname.controller" })
    public class MvcConfig extends WebMvcConfigurerAdapter {
        @Bean
        public InternalResourceViewResolver viewResolver() {
            InternalResourceViewResolver resolver = new InternalResourceViewResolver();
            resolver.setPrefix("/WEB-INF/jsp/");
            resolver.setSuffix(".jsp");
            return resolver;
        }

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/res/**").addResourceLocations("/res/");
    }
    }

security config

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true,jsr250Enabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    private CustomUserDetailsService customUserDetailsService;

public SecurityConfig() {
    customUserDetailsService = new CustomUserDetailsService();
}

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth)
        throws Exception {
    auth.inMemoryAuthentication().withUser("user").password("password")
            .roles("USER");
    auth.userDetailsService(customUserDetailsService);
}

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/res/**").permitAll()
            .and().authorizeRequests()
            .anyRequest().hasRole("USER")
            .and().formLogin().loginPage("/account/signin").permitAll()
            .and().logout().permitAll();
    }
}

security initializer

public class SecurityInitializer extends
        AbstractSecurityWebApplicationInitializer {

}

custom login

public class CustomUserDetailsService implements UserDetailsService {

    private AccountRepository accountRepository;

    public CustomUserDetailsService() {
        this.accountRepository = new AccountRepository();
    }

    @Override
    public UserDetails loadUserByUsername(String email)
            throws UsernameNotFoundException {

        Account account = accountRepository.getAccountByEmail(email);

        if (account == null) {
            throw new UsernameNotFoundException("Invalid email/password.");
        }

        Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        authorities.add(new SimpleGrantedAuthority("USER"));

        return new User(account.getEmail(),account.getPassword(),authorities);
    }
}

但是，现在我有关于自定义登录的新问题。

发布到j_spring_security_check时，我会收到http 302。

我正在请求/，但登录后仍保留在登录页面上。

因为我使用的是Spring Security 4.x版本，并且纯粹基于代码的配置，所以在Internet上找不到更多参考。任何人都可以帮助找出原因。

EDIT

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name ''securityConfig'': 
Injection of autowired dependencies failed; 
nested exception is org.springframework.beans.factory.BeanCreationException:
Could not autowire field: 
private org.springframework.security.core.userdetails.UserDetailsService sg.mathschool.infra.SecurityConfig.userDetailsService; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:

{@org.springframework.beans.factory.annotation.Autowired(required=true),@org.springframework.beans.factory.annotation.Qualifier(value=userDetailsService)}

I changed CustomUserDetailsService

@Service("userDetailsService")
public class CustomUserDetailsService implements UserDetailsService {

    private AccountRepository accountRepository;

    public CustomUserDetailsService() {
        this.accountRepository = new AccountRepository();
    }

    @Override
    @Transactional(readOnly = true)
    public UserDetails loadUserByUsername(String email)
            throws UsernameNotFoundException {

        Account account = accountRepository.getAccountByEmail(email);

        if (account == null) {
            throw new UsernameNotFoundException("Invalid email/password.");
        }

        Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        authorities.add(new SimpleGrantedAuthority("USER"));

        return new User(account.getEmail(),authorities);
    }
}

和 security config

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true,jsr250Enabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("userDetailsService")
    private UserDetailsService userDetailsService;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.inMemoryAuthentication().withUser("user").password("password")
                .roles("USER");
        auth.userDetailsService(userDetailsService).passwordEncoder(
                passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/res/**").permitAll()
                .antMatchers("/account/**").permitAll().anyRequest()
                .hasRole("USER").and().formLogin().loginPage("/account/signin")
                .failureUrl("/account/signin?error").usernameParameter("email")
                .passwordParameter("password").and().logout()
                .logoutSuccessUrl("/account/signin?logout").and().csrf();

    }

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